94-469: The EF lens mount is the standard lens mount on the Canon EOS family of SLR film and digital cameras. EF stands for "Electro-Focus": automatic focusing on EF lenses is handled by a dedicated electric motor built into the lens. Mechanically, it is a bayonet-style mount , and all communication between camera and lens takes place through electrical contacts; there are no mechanical levers or plungers. The mount

188-548: A mirrorless interchangeable-lens camera ( Mirrorless ILC) , or digital single-lens mirrorless , DSLM ) is a digital camera which, in contrast to DSLRs , does not use a mirror in order to ensure that the image presented to the photographer through the viewfinder is identical to that taken by the camera. They have come to replace DSLRs, which have historically dominated interchangeable lens cameras. Other terms include electronic viewfinder interchangeable lens ( EVIL ) cameras and compact system cameras ( CSCs ). Lacking

282-442: A 52mm or 58mm "accessory/filter" screw thread. Canon's close-up, wide- (WC-DC), and tele-conversion (TC-DC) lenses have 2, 3, and 4-element lenses respectively, so they are multi-element lenses and not diopter "filters". Lens mount adapters are designed to attach a lens to a camera body with non-matching mounts. Generally, a lens can be easily adapted to a camera body with a smaller flange focal distance by simply adding space between

376-752: A 6K capture at up to 60p. Nikon then released the Z8 in May 2023, which has the same CMOS sensor, 8K video, and 20-30fps shooting rate modes as the Z9 in a smaller body. Meanwhile, Sony announced the a9 III in November 2023, the first modern mirrorless camera with a global shutter. The shutter allows less lag or motion blur by capturing each pixel of the image at the same time. The 24-megapixel CMOS full-frame shutter can also shoot at 120 frames per second, while being able to capture at shutter speeds as fast as 1/80000 second. A full-frame camera

470-631: A DSLR as possible. There are other terms that were created, too, but mirrorless became the most popular. The first mirrorless camera commercially marketed was the Panasonic Lumix DMC-G1 , released in Japan in October 2008. It was also the first camera of Micro Four Thirds system , developed exclusively for the mirrorless ILC system. The Ricoh GXR (November 2009) had a radically different design. The mirrorless camera featured interchangeable lens units –

564-579: A Panavision rental house, whereas the PL-mount style is favored with most other cameras and cine lens manufacturers. Both of these mounts are held in place with locating pins and friction locking rings. Other mounts which are now largely historical or a minority in relation to current practices are listed below. For small camera modules, used in e.g. CCTV systems and machine vision , a range of metric thread mounts exists. The smallest ones can be found also in e.g. cellphones and endoscopes. The most common by far

658-538: A built-in optical viewfinder. Its hybrid viewfinder overlaid electronic information, including shifting frame-lines, to compensate for the parallax effect. Its 2016 successor, the X-Pro2 , had an updated version of this viewfinder. Beyond just consumer interest, mirrorless lens systems created significant interest from camera manufacturers as a possible alternative to high-end camera manufacturing. Mirrorless cameras have fewer moving parts than DSLRs, and are more electronic, which

752-476: A camera or the camera is switched off, changing the focus is impossible. All stepping-motor lenses are marked with the letters "STM" on the front of the lens as part of the model designation. The image stabilization (IS) technology detects handheld motion and optically corrects it. It only corrects handheld motion; if the subject of the photograph is moving, IS will not stop it. It also can only stabilize so much motion, ranging from two to five stops, depending on

846-632: A constant maximum aperture. All L lenses are supplied complete with a hood and a pouch or case, which are not generally included with non-L lenses. Distinctive visual cues include a red ring around the lens and an off-white colour on longer-focal-length models. The latter also helps to reflect light and reduce heat absorption and subsequent internal expansion of lens components that can affect the image quality of long focal length lenses. All L lenses include at least one fluorite , ultra-low- dispersion glass element, super ultra-low- dispersion glass element, and/or certain types of aspherical elements . (Note that

940-545: A focus of innovation, cameras like the Canon EOS R7 or the R10 , alongside Fujifilm's X-H2 and X-H2S , highlighted how APS-C cameras could offer professional-grade specs like high burst rates and advanced autofocus, all while remaining compact and more affordable than full-frame systems. These systems have leaned more on a emphasis on Content Creators such as vlogging and YouTube. In 2022, mirrorless systems continued to dominate

1034-511: A gold ring and the word "Ultrasonic" printed in gold on the lens barrel. L lenses with USM don't have the gold ring, but they still have the word "Ultrasonic" printed on the lens barrel. Canon announced stepping motor (STM) lenses first in June 2012, alongside the EOS 650D/Rebel T4i/Kiss X6i . Canon stated that this technology allows smooth and silent autofocus, and with compatible bodies (the first of which

1128-607: A leader in hybrid photo-video equipment. The EOS R6 was viewed as the affordable sibling, offered 20 MP stills, 4K 60 fps video, and 8 stops of image stabilization, appealing to enthusiasts and professionals alike. Also in July 2020, Sony announced the A7S III and this camera was a much-anticipated camera as it was aimed at professionals, especially videographers, as it retained a focus on low-light performance and video features. Throughout 2020 there had been major improvements with achieving

1222-456: A lens with Fluoride coating. That lens was the Canon EF 70-300mm f/4-5.6L IS USM. Canon in 2011 made the first fisheye zoom lens, both circular and rectangular. That lens was the Canon EF 8-15mm f/4L Fisheye USM. Lens mount A lens mount may be a screw-threaded type, a bayonet -type, or a breech-lock (friction lock) type. Modern still camera lens mounts are of the bayonet type, because

1316-602: A manual connection, the aperture and focus controls of the lens cannot be controlled or read from the camera; the lens must be focused manually. Since the only possible metering is through-the-lens, the lens must be manually stopped down to accurately meter at anything less than full aperture. (This is called stop-down metering .) Compatible third-party lenses with the EF lens mount are manufactured by Yongnuo , Samyang , Schneider , Sigma , Tamron , Tokina , Cosina and Carl Zeiss . The manufacturers of these lenses have reverse engineered

1410-453: A mirror system allows the camera to be smaller, quieter, and lighter. In cameras with mirrors, light from the lens is directed to either the image sensor or the viewfinder . This is done using a mechanical movable mirror which sits behind the lens. By contrast, in a mirrorless camera, the lens always shines light onto the image sensor, and what the camera sees is displayed on a screen for the photographer. Some mirrorless cameras also simulate

1504-481: A number of controls, switches and physical features, used by the photographer to control the lens. The types and number of the controls can vary from lens to lens. With the most basic lenses having only a few, to the most complex having over a dozen different controls and switches. This is a list of the different controls and switches found on most Canon EF lenses, along with a detailed description on what they are used for. Lens mount index: This raised, round red mark

1598-428: A number of non-L lenses also use aspherical elements, and at least one non-L lens has a Super UD element.) Most L lenses feature an ultrasonic motor (USM) for focusing. In 1987 Canon was the first to use USM (Ultra Sonic Motor) with the Canon EF 300mm f/2.8L USM. In 1989 Canon was the first to create a full frame f/1.0 AF (AutoFocus) lens and the only one until today with the Canon EF 50mm f/1.0L USM. In 1993 Canon

1692-426: A primary lens mount. Various lensmakers also offer optical accessories that mount in front of the lens; these may include wide-angle , telephoto , fisheye , and close-up or macro adapters. Canon PowerShot A and Canon PowerShot G cameras have a built-in or non-interchangeable primary (zoom) lens, and Canon has "conversion tube" accessories available for some Canon PowerShot camera models which provide either

1786-520: A sealed unit of a lens and sensor, instead of the lens only being interchangeable. This design was different from other mirrorless cameras, and received mixed reviews, primarily due to its higher cost. The 2010's Following the introduction of the Micro Four Thirds system, several other cameras were released by Panasonic and Olympus, with the Olympus PEN E-P1 (announced June 2009) being

1880-492: A successor to the earlier and successful Mark I. The Mark II model retains a Micro Four Thirds image sensor of 17.3x13 mm and features a 20.4 megapixel resolution sensor, representing a new generation of mirrorless cameras competitive with and in many respects superior to DSLR cameras. In early 2017, Sony announces the Alpha-9 mirrorless camera, offering 693 autofocus points, and 20 frame-per-second shooting. In October Sony announces

1974-465: A traditional viewfinder using a small screen, known as an electronic viewfinder (EVF). DSLRs can act like mirrorless cameras if they have a " live view " mode, in which the mirror moves out of the way so the lens can always shine onto the image sensor. Many mirrorless cameras retain a mechanical shutter . Like a DSLR, a mirrorless camera accepts interchangeable lenses. Mirrorless cameras necessarily have shorter battery life because they need to power

Mirrorless interchangeable-lens camera A mirrorless camera (sometimes referred to as

2162-435: Is a digital camera with a digital sensor the same size as 35 mm format ( 36 mm × 24 mm ) film. Cameras that have a smaller sensor than full-frame (such as APS-C and Micro Four Thirds ) differ in having a crop factor . Digital cameras with a larger sensor than full-frame are called medium format, after medium format film cameras that use the 120 and 220 film formats (although their sensors are generally much smaller than

2256-469: Is an advantage to electronic manufacturers (such as Panasonic, and Samsung), while reducing the advantage that dedicated camera manufacturers have in precision mechanical engineering . Sony's entry level full frame mirrorless α7 II camera has a 24- megapixel 5-axis stabilised sensor, but is more compact and less expensive than any full-frame sensor DSLR. Canon was the last of the major manufacturer of DSLRs to announce their own mirrorless camera, announcing

2350-450: Is desired. The "set" button is used for saving the focus distance into memory. The focus preset ring is used for recalling the memory save point. It is a thin knurled ring, usually located in front of the Focusing ring . To use this feature, one must set the switch to either "on" or "on with sound", focus the lens to the desired distance, then press the "set" button. After this, when the feature

2444-445: Is doing infrared photography, as lenses typically focus infrared light at a different point than visible light, and therefore achieving correct focus using visible light will result in an out-of-focus infrared image. To make an adjustment, first focus the subject, then turn the Focusing ring so it matches the corresponding infrared index mark. Focus mode switch: This switch is found on most EF lenses that have an autofocus feature. It

2538-478: Is found on all EF lenses that feature an image stabilizer. It is used for turning the image stabilizer "on"( | ), or "off"( o ). Image stabilizer mode switch: This switch is found on many EF lenses that feature an image stabilizer, particularly those of longer focal lengths. The switch has two settings on most lenses: Mode 1 and Mode 2. The newest IS Mark II versions of certain EF super telephoto lenses (the 300mm f/2.8L, 400mm f/2.8L, 500mm f/4L, and 600mm f/4L), plus

2632-403: Is found on all EF lenses. It is used for matching the EF lens mount to the mount on an EOS body, so one can connect the lens to the body quickly. Focusing ring: This control, found on most EF lenses, is used for focusing the lens. It is usually a ring on the lens body, that can be turned. Zoom ring: This control is found on most EF zoom lenses . It is used for changing the focal length of

2726-415: Is found on most super telephoto EF lenses. The focus preset feature uses one switch, one button, and one ring. It is used for presetting a given focus distance into memory, so that the photographer can quickly recall the focus distance, without the need for autofocus. The switch has three settings "off"( o ), "on"( | ), or "on with sound"( ( ( - ), and is used for turning on the feature, and deciding if sound

2820-674: Is partially or entirely missing for the autofocus "pixels", which can cause banding artifacts in the final image. The 2000's The first digital rangefinder camera commercially marketed was the Epson R-D1 (released in 2004), followed by the Leica M8 in 2006. They were some of the first digital lens-interchangeable cameras without a reflex mirror, but they are not considered mirrorless cameras because they did not use an electronic viewfinder for live preview, but, rather, an optical viewfinder. Compact cameras with large sensors, technically akin to

2914-500: Is possible to have a camera so compact and relatively affordable (comparing to traditional cinema cameras ) could meet the high standards of a professional camera for film making. The 2020s In July 2020, Canon announced both the EOS R5 and R6 as a way to bring more Mirrorless cameras to their line up. The EOS R5 camera was so significant as it was the first camera to be capable of 8K RAW video recording at up to 30 fps, positioning it as

3008-493: Is possible to mount lenses using the Nikon F mount , Olympus OM, Leica R and universal M42 lens mounts (among others) by the use of a mechanical adapter without electronic control of the aperture or autofocus. In contrast, parfocal adaptation of EF lenses to non-EF camera bodies is not possible with only a mechanical adapter that does not contain optical elements. EF mount lenses are somewhat compatible with newer Canon bodies, though

Two main disadvantages are linked to focus-by-wire: First, the need to computationally process the input before the intended action is executed leads to a sometimes perceptible lag. Second, using the motor requires power, so when an STM lens is not connected to

So some manufacturers (e.g. Linhof ) offered special focusing lens mounts, so-called wide-angle focusing accessories for their cameras. With such a device, the lens could be focused precisely without moving

3290-548: Is turned on, the photographer can turn the focus preset ring, and the lens will recall and focus quickly to the distance that was saved. This feature is useful for sports and birding photography (for instance, to allow rapid focusing on the goal or on a spot where the birds may perch). Filter mounting: This mount is used for attaching filters to EF lenses. There are three types: front threaded mount, inner drop-in mount, and rear gelatin holders. Front threaded filters are used on most lenses, and are attached by threading and tightening

3384-405: Is used for setting the lens to either autofocus mode, or manual focus. When set to autofocus mode (AF), the lens will autofocus when directed to by the camera. When set to manual focus (MF), the lens is focused using the Focusing ring . Some lenses support full-time manual focusing (FT-M), which allows the photographer to focus the lens manually even with the mode switch set to AF, without damaging

3478-574: Is used to bring down the cost of the lens. It is possible to implement FT-M even with micromotor USM; however, it requires additional mechanical components, and the vast majority of micro-USM lenses do not offer such capability. Nano USM was introduced in 2016 with the release of Canon's latest iteration of the EF-S 18–135mm lens . It is intended to offer the AF speed of ring-type USM with the quietness of STM mechanisms (see below). Some older USM lenses are identified with

The Alpha 1 was aimed to unify both photography and videography at a professional level. A day later, Fujifilm releases the GFX 100s and it had a smaller and lighter body holding a 102 MP medium-format sensor. This camera is compared to the original GFX 100 with 6 stops of in-body image stablization (IBIS) and 4K video recording at 30 fps. Nikon, towards

Mode 2 is used for panning; this is useful for sports or wildlife photography, where the subject moves constantly and one will need to pan. Mode 3, intended to track action, is similar to Mode 2 in that it ignores panning; however, it only applies stabilization when

4230-498: The Americas in 2015, DSLR annual sales fell by 16% per annum, while mirrorless sales over the same 12-month period have increased by 17%. In Japan, mirrorless cameras outsold DSLRs during some parts of the year. In 2015, mirrorless-cameras accounted for 26 percent of interchangeable-lens camera sales outside the Americas, although a lesser share of 26 percent was in the U.S. In late 2016, Olympus announced their OM-D E-M1 Mark II camera,

4324-533: The Americas, and 16 percent within the United States. As of 2023, mirrorless cameras have come to overtake DSLRs as the dominant kind of interchangeable lens camera, with them gaining market share over DSLRs, and nearly all camera manufactures have switched entirely and exclusively to making mirrorless cameras and lenses. Until the mid 2010s, mirrorless cameras were dismissed by many photographers, because of their laggy and low resolution screens, when compared with

4418-474: The EF 400 mm f / 4 DO IS USM, its updated Mark II version, and the EF 70–300 mm f / 4.5–5.6 DO IS USM contain DO elements. DO lenses have a green ring on the barrel. Top range Canon EF lenses are designated "L-series", or "Luxury" lenses. L series lenses are compatible with the full range of EF or EF-S mounts and, as they are aimed at the high-end user, most also include environmental or weather sealing and

The use of these third-party lenses is not supported by Canon. Sometimes compatibility problems arise, as no third party has access to Canon's specifications for camera-to-body communication. These compatibility issues mostly occur when using a newer body with an older third-party lens. Over time, most of these issues have been resolved by

4606-710: The NAB Show in April 2018, Blackmagic Design announced and demonstrated the Pocket Cinema Camera 4K at a price of $ 1,295 USD. In early 2019, Canon officially announces their second full-frame mirrorless camera following the EOS R introduced in 2018. That said camera is the EOS RP as it was made to be an entry-level for a mirrorless. In July 2019, Sony announces the A7R IV with a ground breaking 61-megapixel full-frame sensor, making it

4700-757: The Panasonic LUMIX BS1H earned Netflix approval, further highlighting the growing acceptance of mirrorless cameras in high-end filmmaking. Additionally, the Nikon Z9 was honored with the prestigious "Camera of the Year" and "Readers Award" at the Camera Grand Prix 2022, recognizing its groundbreaking performance and impact on the camera industry. In April 2023, Canon released the EOS R8 , and it contains various autofocus capabilities for recognizing subjects and 4K video from

4888-472: The ability to shoot in low light to being able to record in 8K RAW, 2020 was one of the most impactful years as it introduced new things to both photography and videography. The year 2021 marked a turning point for mirrorless cameras, as they surpassed DSLRs in shipments, accounting for over 67% of total camera sales. On January 26, 2021, Sony announced the Alpha 1 and it had set the benchmark as it competed with

4982-406: The additional setting usually being near focus range (from minimum focus distance to halfway point of focus range). Longer focal length lenses and macro lenses have a relatively long travel distance for the focusing mechanism inside the lens; this feature shortens the autofocus time. When the photographer knows they will not need a certain part of the focus distance range, limiting it will help shorten

5076-435: The autofocus time, and possibly prevent "focus hunting". Soft focus ring: This ring is found only on the 135 mm 'Soft Focus' prime lens, and enables a variable soft focus effect from completely sharp (0) to very soft (2), although it has little effect when used with apertures over f/5.6. Although the ring can be set to any position, two 'stops' are implemented at positions 1 and 2. Image stabilizer switch: This switch

5170-410: The base of the lens, which fit into appropriately sized recesses in the lens mounting plate on the front of the camera. The tabs are often "keyed" in some way to ensure that the lens is inserted in only one orientation, often by making one tab a different size. Once inserted the lens is fastened by turning it a small amount. It is then locked in place by a spring-loaded pin, which can be operated to remove

5264-449: The bayonet mechanism precisely aligns mechanical and electrical features between lens and body. Screw-threaded mounts are fragile and do not align the lens in a reliable rotational position, yet types such as the C-mount interface are still widely in use for other applications like video cameras and optical instrumentation. Bayonet mounts generally have a number of tabs (often three) around

5358-457: The boundaries of image quality, autofocus, and video capabilities. Some exapansions to the mirrorless camera is that hybrid cameras had gained a dominance as cameras like the Canon EOS R5 C and Fujifilm X-H2S are catered to professionals going for high-resolution photo performance alongside 8K recording and internal ProRes capabilities. Some more improvements are how the APS-C format had become

5452-521: The camera and the lens. When attempting to adapt a lens to a camera body with a larger flange focal distance, the adapter must include a secondary lens in order to compensate. This has the side effect of decreasing the amount of light that reaches the sensor, as well as adding a crop factor to the lens. Without the secondary lens, these adapters will function as an extension tube and will not be able to focus to infinity. ^   A:  The authoritative normative source for 4/3 standards information

5546-844: The camera body, and each FD lens provided a breech-lock receptacle to register and fasten the lens to the bayonet. The EF mount reverses this logic, providing the bayonet on each lens, and a receptacle on the camera body. When the EF mount was introduced in 1987, it had the largest mount diameter (54 mm internal) among all 35 mm SLR cameras. The EF series includes over eighty lenses, encompassing focal lengths from 8 to 1200 mm. Many EF lenses include such features as Canon's ultrasonic motor (USM) drive, an image stabilization system (IS), diffractive optics (DO) and, particularly for L-series lenses, fluorite and aspherical lens elements. Its large diameter and relatively short flange focal distance of 44.0 mm allows mechanical adaptation of EF camera bodies to many types of non-EF lenses. It

5640-464: The camera included LA-EA1 and LA-EA2 adapters for the legacy Minolta A-mount . In June 2011, Pentax announced the 'Q' mirrorless interchangeable lens camera and the 'Q-mount' lens system. The original Q series featured a smaller 1/2.3 inch 12.4 megapixel CMOS sensor. The Q7, introduced in 2013, has a slightly larger 1/1.7 inch CMOS sensor with the same megapixel count. In September 2011, Nikon announced their Nikon 1 system which consists of

5734-516: The clarity and responsiveness of the optical viewfinders used on DSLRs, especially under strong sunlight or when photographing the sky at night. In addition, mirrorless cameras were known for having worse autofocus performance compared to DSLRs, and much worse battery life. This negative perception of mirrorless cameras began to change around 2013, when the Sony α7 was released. It was the first professional, full frame mirrorless camera, and, although not

5828-474: The current mirrorless cameras, were also marketed in this period. Cameras like Sony Cyber-shot DSC-R1 and Sigma DP1 proved that live preview operation is possible, and useful with APS-C sized sensors. The term mirrorless came into use in order to describe Micro Four Thirds cameras when they were announced in 2008, especially as the first Micro Four Thirds camera, the Lumix G1 , was designed to be as similar to

5922-517: The digital camera market, accounting for 69% of interchangeable lens camera shipments—a 31% increase from the previous year, as reported by CIPA. Among the most impactful releases of the year were the Canon EOS R7 (June 2022), and the Sony FX30 (September 2022), both of which offer 4k video up to 60 fps but the FX30 to it further to 120fps. The R7 featured one of the highest performing APS-C sensors of

6016-565: The end of the year in October, released the Z9 , its flagship full frame mirrorless model. It featured some Nikon's best autofocus performance with 3d tracking, 8k video, 60 fps RAW shooting as well as offering cutting-edge speed and reliability with its stacked CMOS sensor. In 2021, Sony led the market with a 32% share, followed closely by Canon at 28.2%, reflecting the growing preference for compact, versatile, and professional-grade systems. These cameras catered to both photographers and filmmakers, pushing

6110-413: The entire front standard. Secondary lens refers to a multi-element lens mounted either in front of a camera's primary lens, or in between the camera body and the primary lens. (D)SLR camera & interchangeable-lens manufacturers offer lens accessories like extension tubes and secondary lenses like teleconverters , which mount in between the camera body and the primary lens, both using and providing

6204-503: The filter. Inner, drop-in filter mounts are used on super telephoto EF lenses. They are attached by first pressing the two buttons on the filter mount, and pulling it out. Then either a round threaded filter is attached, or one can use a gelatin filter. Rear gelatin filter holders are used by cutting out a sheet of gelatin, to the size shown on the back of the lens and then sliding it into the holder. Filter mounts are useful for all types of photography, and every EF lens has either one or two of

6298-497: The first mirrorless camera in a compact size (pocketable with a small lens). The Samsung NX10 (announced January 2010) was the first camera in this class not using the Micro Four Thirds system, instead utilizing a new, proprietary lens mount ( Samsung NX-mount ). The Sony Alpha NEX-3 and NEX-5 (announced May 14, 2010, and released in July 2010) saw Sony enter the market with a new, proprietary lens mount (the Sony E-mount ), though

6392-495: The first nine months of 2013, and 10.5% of those shipped to the U.S. in the same period. An industry researcher found that mirrorless camera sales in the U.S. fell by about 20% in the three weeks leading up to December 14, 2013—which included the key Black Friday shopping week; in the same period, DSLR sales went up 1%. In 2013, mirrorless system cameras constituted about five percent of total camera shipments. In 2015, they accounted for 26 percent of system camera sales outside of

6486-517: The first with depth aware autofocus, included small additional sensors on the main sensor to detect depth in the scene, for fast autofocus ("phase-detect"). 2015 sales statistics showed that overall camera sales have fallen to one third of those of 2010, due to compact cameras being substituted by camera-capable mobile phones. Within camera sales, Mirrorless ILCs have seen their market share increasing, with ILCs being 30% of overall camera sales, of which DSLRs were 77% and mirrorless cameras were 23%. In

6580-654: The frame size of medium format film cameras). Sony was the first to introduce a full-frame mirrorless camera, the α7 , in 2013. It was followed by the Leica SL (Typ 601) in 2015. Nikon and Canon each launched full-frame mirrorless cameras in September 2018. Panasonic and Sigma, under the L-Mount Alliance , announced that they will be using the Leica L-Mount for their own full-frame mirrorless cameras. Panasonic announced its S1R and S1 cameras, and Sigma announced

6674-409: The highest-resolution full-frame camera at the time, other improvements included 15 stops of dynamic range and 576-point phase-detection autofocus for exceptional detail and precision. On October 2019, Panasonic's Lumix S1H Became the first hybrid full-frame mirrorless camera certified by Netflix for use in its Original productions. This became a giant milestone in the camera industry by showing that it

6768-515: The indirect focusing system of the DSLR (which relies on a separate autofocus sensor located below the reflex mirror), and as of 2018 mirrorless cameras could shoot with phase-detect autofocus at up to 20 frames per second using up to 693 focus points—a number far exceeding what was available on any DSLR. However, on-sensor phase detection autofocus (except for Canon's Dual Pixel Autofocus ) repurposes pixel sites for autofocus acquisition, so that image data

6862-655: The interchangeable lens market in Japan, 18% in Europe, and 23% worldwide. Since then, Nikon and others entered the mirrorless market. Due to the downward trend of the world camera market, mirrorless camera sales suffered, but not as drastically and was compensated with increase by about 12 percent in the Japanese mirrorless camera market. However, mirrorless cameras took longer to catch on in Europe and North America. According to Japanese photo industry sources, mirrorless made up only 11.2% of interchangeable-lens cameras shipped to Europe in

6956-588: The introduction of the EF 300 mm f / 2.8L USM lens in 1987. Canon was the first camera maker to successfully commercialise the USM technology. EF lenses equipped with USM drives have fast, silent and precise autofocus operations, and consume less power compared to other AF drive motors. There are three types of USMs: ring-type USM , micromotor USM , and Nano USM . Ring-type USM allows for full-time manual focus (FT-M) operations without switching out of AF mode. Micromotor USM

7050-526: The lens (as could happen if a lens without FT-M is manually focused while in AF mode). Focusing distance range limiter switch: This switch is found on most longer focal length lenses, and macro lenses. It is used for limiting the focusing distance range of the lens when using it in autofocus mode. Most lenses have two settings; these are usually full focus range (from minimum focus distance to infinity), and distant focus range (from halfway point of focus range to infinity ). Other lenses have three settings, with

7144-438: The lens. Lens mounts of competing manufacturers (Sony, Nikon, Canon, Contax/Yashica, Pentax, etc.) are almost always incompatible. In addition to the mechanical and electrical interface variations, the flange focal distance from the lens mount to the film or sensor can also be different. Many allege that these incompatibilities are due to the desire of manufacturers to " lock in " consumers to their brand. In movie cameras,

7238-487: The lens. Only one button needs to be pressed to activate the feature. To use this button, one must first have the autofocus active, then when one wishes to halt autofocus, one presses and holds the button. To resume autofocus, one releases the button. Some newer bodies allow these buttons to be assigned to perform other functions; for instance, the Canon EOS 7D allows the photographer to set these buttons to perform any of six functions. Focus preset: The focus preset feature

7332-401: The lens. The zoom ring usually has certain, common, focal lengths marked on it. To set the zoom ring to any given focal length, one must turn the ring so that the marked focal length matches the zoom index. The zoom index is typically a white, or black, line found next to the zoom ring. Distance scale window: This feature is found on many EF lenses. This feature, while not a control or switch,

7426-698: The major third-party brands. Due to the high market penetration of EF-mount lenses, other camera manufacturers began to offer EF-mount cameras. Since the EF-mount was created for SLR cameras with their long focal flange distance, mirrorless interchangeable-lens cameras can use EF lenses with a mechanical adaptor that bridges the distance. Red Digital Cinema Company offers various camera models that can be equipped with an electronic EF-mount. Many Blackmagic Design cameras are sold in EF-mount variants. For Sony E-mount various adaptors enable using EF-mount lenses with full electronic control. Canon EF lenses typically have

7520-406: The mirror is locked up into "live view" mode. This includes the ability to show a focus-peaking display, zebra patterning , and face or eye tracking . The electronic viewfinder can provide live previews of depth of field , exposure, white balance and picture style settings, as well as offer a real time view of camera settings even in extremely low or bright light levels, making it easier to view

7614-408: The results. With the latest phase-detect autofocus available on some mirrorless cameras, the autofocus speed and accuracy of some models has been shown to be as good as DSLRs. But mirrorless cameras have shorter battery life than DSLRs due to prolonged use of LCD and/or OLED viewfinder displays, and often smaller buffers (to save battery). On-sensor autofocus is free of the adjustment requirements of

7708-466: The reverse is not true: Lenses for the earlier Canon FD lens mount are not usable for general photography on an EF mount cameras, unless adapters with optical elements are used because they are made for a flange focal distance of only 42.0 mm. Infinity focus would be lost with an adapter which lacks optical elements. The Canon FD-EOS adapter is rare and is only usable with certain FD telephoto lenses. With

7802-515: The screen and sensor at all times. Mirrorless cameras are mechanically simpler than DSLR cameras, and are smaller , lighter , and quieter due to the elimination of the moving mirror. While nearly all mirrorless cameras have a mechanical shutter, many also have an electronic shutter, allowing completely silent operation. As the image from the lens is always projected onto the image sensor, features can be available which are only possible in DSLRs when

7896-537: The shutter is released—the viewfinder image is not stabilized. One should not use Mode 1 for panning as this will typically cause blurred photographs; the image stabilizer will attempt to correct for all motion, including the panning motion, but cannot do so due to the limited range of motion of the IS mechanism. Older lenses that have an image stabilizer, but do not feature this switch, are permanently in Mode 1. Some newer lenses, such as

7990-610: The specific IS in the lens. Canon has released several versions of the IS system, including the following: All EF lenses that support IS have the words "Image Stabilizer" written on the lens. On some of Canon's larger telephoto lenses, the words "Image Stabilizer" are etched onto a metal plate affixed to the lens. Diffractive optics (DO) are special lens elements that are used in some lenses. DO lenses are usually smaller and lighter and are better at handling chromatic aberration , compared to conventional lenses of similar focal length and aperture value. They are more expensive to make. Only

8084-407: The three types used. Lens hood mount: This feature is found on most EF lenses. This mount is used for attaching the lens hood . The hood mount is of a bayonet style on most EF lenses, though a clip-on style hood mount is used for a small selection of current lenses. Tripod collar: This feature is found on most longer focal length lenses, and macro lenses. The tripod collar is used for attaching

8178-465: The tripod ring matches the index mark on the distance scale. The tripod ring is used for attaching a tripod/monopod near to the point of balance of the lens-body combination, more conveniently than the camera body. In the case of larger and heavier lenses, there is also less strain on the lens mount if the body is supported by the tripod-mounted lens than if the lens were to be supported by a tripod-mounted body. Ultrasonic motor (USM) lenses appeared with

8272-409: The tripod ring. There are two main styles of tripod rings. One type is opened up, placed on the lens' tripod collar, then closed and tightened. The other type does not open, but instead is slid up the lens from the mount end (which can only be done when the lens is not mounted on a camera body) and tightened. To set the tripod ring so that it is level with the lens, rotate the ring until the index mark on

8366-450: The two most popular mounts in current usage on professional digital cinematography cameras are Arri 's PL-mount and Panavision 's PV-mount . The PL-Mount is used both on Arri and RED digital cinematography cameras, which as of 2012 are the most used cameras for films shot in digital . The Panavision mounts are exclusively used with Panavision lenses, and thus are only available on Panaflex cameras or third-party cameras "Panavised" by

8460-556: The year with 32 megapixels only slightly surpassed by the Fujifilm X-T5 (November 2022) with 40 megapixels. The X-T5 was also a top perfromer in video quality with 6.2k at 30fps and 7 stops of IBIS. Nikon’s Z30 catered to content creators with its user-friendly video-centric design. The OM System OM-1 pushed the boundaries of Micro Four Thirds with a stacked BSI Live MOS sensor and up to 50 fps of continuous shooting, appealing to wildlife and action photographers. In March of 2022,

8554-446: Was first introduced in 1987. Canon claims to have produced its 100-millionth EF-series interchangeable lens on April 22, 2014. The EF mount replaces its predecessor, the FD mount . The standard autofocus lens mounting technology of the time used a motor in the camera body to drive the mechanics of the focus helicoid in the lens by using a transfer lever. The key innovation of the EF series

8648-404: Was the Canon EF 400mm f/4 DO IS USM. Canon in 2008 created the first lens with SWC technology (Subwavelength Structure Coating). That lens was the Canon EF 24mm f/1.4L II USM. Canon in 2009 created the first lens with Hybrid IS (Image Stabilization) which compensates both angle camera shake and shift camera shake with the Canon EF 100mm f/2.8L Macro IS USM. Canon in 2010 was the first to create

8742-473: Was the first to create an interchangeable 10× superzoom lens for SLR cameras. That lens was Canon EF 35-350mm f/3.5-5.6L USM. In 1993 Canon created the first Super UD (Ultra low Dispersion) lens with the Canon EF 400mm f/5.6L USM. In 1995 Canon created the first lens with IS (Image Stabilization). That lens was the Canon EF 75-300mm f/4-5.6 IS USM. Canon in 2001 was the first to create a lens with DO (multi layered Diffractive Optical element) element. That lens

8836-426: Was to use a motor inside the lens itself for focusing. This allowed for autofocusing lenses which did not require mechanical levers in the mount mechanism, only electrical contacts to supply power and instructions to the lens motor. The motors were designed for the particular lens they were installed in. The EF mount reversed the mechanical logic of the FD mount. The FD mount provided the three-eared bayonet fitting on
