The EOS C300 is a digital cinema camera in the Cinema EOS range. It was announced by Canon on November 3, 2011.
60-599: The camera is offered with the option of Canon EF or Arri PL mounts. It has been available since January 2012. In September 2015, Canon released an updated version, the Canon EOS C300 Mark II . In 2011, the Canon EOS C300 was originally announced with the following characteristics: Vincent Laforet was given access to a pre-release version of the EOS C300 to shoot the short film Möbius (2011). In addition,
120-522: A CPU enabled lens; the aperture of G designated lenses cannot be controlled without an electronic camera body; non-AI lenses (manufactured prior to 1977) can cause mechanical damage to later model bodies unless they are modified to meet the AI specification; and AF-P lenses (introduced in 2016) will not focus, even manually, on cameras introduced before roughly 2013. Many manual focus lenses can be converted to allow metering with consumer Nikon bodies by adding
180-560: A Dandelion chip to the lens. Most Nikon F-mount lenses cover a minimum of the standard 36×24 mm area of 35mm format and the Nikon FX format , while DX designated lenses cover the 24×16 mm area of the Nikon DX format , and industrial F-mount lenses have varying coverage. DX lenses may produce vignetting when used on film and FX cameras. However, Nikon lenses designed for film cameras will work on Nikon digital system cameras with

300-406: A PC-E lens operates like a PC lens. The PC Micro-Nikkor 85 mm f / 2.8D lens offers only preset aperture control, actuated mechanically by pressing a plunger. In July 1962, Nikon released the first interchangeable perspective-control lens available for a single-lens reflex camera , the 35mm f / 3.5 PC-Nikkor. This was followed in 1968 by a redesigned 35mm f / 2.8 PC-Nikkor in which
360-476: 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
420-633: 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
480-511: 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
540-462: 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. Nikon F mount The Nikon F-mount is a type of interchangeable lens mount developed by Nikon for its 35mm format single-lens reflex cameras . The F-mount was first introduced on
600-602: 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
660-530: A new optical design. This was the last of the completely manual PC-Nikkors to be offered. Nikkor lenses designated AF-S, AF-I and AF-P have integrated autofocus motors, but other manufacturers included in the list do not designate it as clearly. These lenses are needed for autofocus on certain newer low-end Nikon cameras which lack an autofocus motor . Without autofocus motor are the Nikon D40 , D40X , D60 , D3xxx (most recent: D3500 ), D5xxx (most recent: D5600 ),

#1732884873139720-481: 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
780-429: 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
840-655: 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
900-450: 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
960-445: 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
1020-482: 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
1080-403: 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
1140-415: 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
1200-523: Is opposite of the direction normally used by Canon . F-mount lenses also typically have aperture rings that turn clockwise to close. The aperture rings have two sets of f-stop numbers. On cameras equipped with Nikon's Aperture Direct Readout (ADR) system, a small window under the pentaprism reads the smaller scale and displays the selected f-stop in the viewfinder . Nikon has introduced many proprietary designations for F-mount Nikkor lenses, reflecting design variations and developments both in lenses and
1260-493: 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
1380-548: 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
1440-405: 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
1500-574: 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
1560-408: Is useful to the photographer for determining, or setting, the lens's focus distance. It is used in conjunction with the Focusing ring . When rotated, the distance scale will also rotate to show the changing focus distance. On some lenses the distance scale also has an infrared index. These are shown as red markings below the distance scale. This is used for making focus adjustments when the photographer
1620-469: The Canon EF-S 18-200mm lens , are able to detect if they are being panned in either axis and will automatically disable the stabilization for the axis parallel to movement and therefore do not require this switch. Autofocus stop buttons: These buttons are found on some super telephoto EF lenses, evenly spaced around the front collar of the lens. They are used for temporarily stopping the autofocus feature of
1680-589: 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 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,
1740-493: 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 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

They are manufactured by Cosina to Zeiss specifications. Four design variations are designated ZF, ZF.2, ZF-I, and ZF-IR. ZF is the original product line. ZF.2 lenses are CPU-enabled (similar to Nikon AI-P lenses) offering full metering compatibility with
1860-478: The Nikon F camera in 1959, and features a three-lug bayonet mount with a 44 mm throat and a flange to focal plane distance of 46.5 mm. The company continues, with the 2020 D6 model, to use variations of the same lens mount specification for its film and digital SLR cameras . The Nikon F-mount successor is the Nikon Z-mount . The Nikon F-mount is one of only two SLR lens mounts (the other being

1920-472: The Pentax K-mount ) which were not abandoned by their associated manufacturer upon the introduction of autofocus , but rather extended to meet new requirements related to metering , autofocus , and aperture control. The large variety of F-mount compatible lenses makes it the largest system of interchangeable flange-mount photographic lenses in history. Over 400 different Nikkor lenses are compatible with
1980-436: The 200–400mm f/4L IS and 100–400mm f/4–5.6L IS II, have a third setting, Mode 3. Mode 1 is normal mode, used for typical photography, where the subject does not move. 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
2040-508: The C300 was used along with Canon EOS DSLRs (such as an infrared-modified Canon EOS 5D Mark II ) on the short film When You Find Me (2011), directed by Bryce Dallas Howard and produced by her father Ron Howard . A Canon EOS C300 was used with a drone to shoot aerial footage on the "small-budget" Kevin Macdonald film How I Live Now (2013). The 2013 feature film Blue Ruin was shot on
2100-475: 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
2160-527: The EOS electronics—except Zeiss, which does not have the rights to use the autofocus or the electronic aperture control of EOS cameras . 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
2220-638: The F-mount in non-photographic imaging applications. The F-mount has a significant degree of both backward and forward compatibility . Many current autofocus F-mount lenses can be used on the original Nikon F , and the earliest manual-focus F-mount lenses of the 1960s and early 1970s can, with some modification, still be used to their fullest on all professional-class Nikon cameras. Incompatibilities do exist, however, and adventurous F-mount users should consult product documentation in order to avoid problems. For example, many electronic camera bodies cannot meter without
2280-484: The F-mount itself. There are also "unofficial" designations used by collectors and dealers to differentiate similar lenses. Nikon PC lenses, like other perspective control lenses , offer adjustments that duplicate certain view camera movements . The 28mm and 35mm PC lenses support shifting the lens in relation to the film or sensor plane, while Nikon's 19mm, 24mm, 45mm, and 85mm PC-E lenses also support tilting . Nikon currently offers four different PC lenses for sale:
2340-406: 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
2400-435: 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
2460-503: 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

2520-452: The four PC-E Nikkors (2008 and 2016), and the 85mm PC-Nikkor (1999). The 45 mm and 85 mm "Micro" lenses offer close focus (0.5 magnification) for macrophotography . The PC- E lenses (the "E" designates an electromagnetic diaphragm) offer automatic aperture control with all DSLRs with CMOS image sensor except the Nikon D90 . With earlier DSLRs and all "analog" film camera models,

ZF-IR lenses are adapted to infrared imaging, with coatings that transmit wavelengths up to 1100 nm, and focus scales marked for infrared. CP.2 lenses are a series of Zeiss "CompactPrime" cinema lenses which present F-mount as one of three mounting options. The lenses cover
2640-588: 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
2700-526: 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
2760-444: 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 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
2820-487: 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
2880-401: 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,
2940-403: The limitations noted above. F-mount lenses lock by turning counter-clockwise (when looking at the front of lens) and unlock clockwise. Nearly all F-mount lenses have zoom and focus controls that rotate in the clockwise direction (as viewed from behind the camera) to increase focal length and focus distance respectively. This convention is also used in Pentax K-mount and Sony A-mount lenses but
3000-698: 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
3060-421: 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

#17328848731393120-473: The shifting portion of the lens was further from the camera's body, in order to clear the new "Photomic" meters. The last optical redesign of this 35mm lens was released in 1980. The 35mm PC-Nikkor did not meet the need of photographers for a wider-angle lens, so in July 1975 Nikon released the 28mm f / 4 PC-Nikkor. In February 1981 Nikon released an improved version of this lens, the 28mm f / 3.5 PC-Nikkor, with
3180-538: 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
3240-610: 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
3300-600: The system. The F-mount is also popular in scientific and industrial applications, most notably machine vision . The F-mount has been in production for over 60 years, the only SLR lens mount with such longevity. In addition to Nikon's own range of " Nikkor " lenses, brands of F-mount photographic lenses include Zeiss , Voigtländer , Schneider , Angénieux , Samyang , Sigma , Tokina , Tamron , Hartblei , Kiev-Arsenal , Lensbaby , and Vivitar . F-mount cameras include current models from Nikon , Fujifilm , Sinar , JVC , Kenko and Horseman. Numerous other manufacturers employ

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
3420-465: 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
3480-409: 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
