The Canon PowerShot S90 is a high-end 10.0-megapixel compact digital camera originally announced in 2009. The PowerShot S90 is the successor of the Canon PowerShot S80 .
73-561: The almost four-year gap between the S80 and the S90, compared with intervals of six months to one year between prior versions, led to the line being popularly considered discontinued, and thus the S90 as a revival, rather than a strict successor. The S90 has received good, in some cases excellent reviews, with reviewers praising its image quality, small size, and ease of using manual mode, particularly due to its distinctive control ring. The fast (f/2) lens and

Viewing is achieved on all models by live view electronic displays with LCD screens. In addition, some models feature a built-in electronic viewfinder (EVF), while others may offer optional detachable electronic viewfinders. An independent optical viewfinder typically matched to
219-462: A hot shoe (except the G7 X and G9 X ) for an external flash , including Canon's EX range . New models in the series (all containing "X" in their name) have larger sensors than most other point-and-shoot cameras. In recent years, smartphones and interchangeable-lens cameras have squeezed the compact point-and-shoot market, and as of February 2024 the vlogger-friendly G7 X Mark II and G7 X Mark III remain
292-447: A 122 mm filter. Olympus and Panasonic have both produced cameras with sensor-based stabilization, and lenses with stabilization. However, the lens stabilization will only work together with body stabilization for cameras of the same brand. Before 2013, Olympus and Panasonic approached image stabilization (IS) differently. Olympus used sensor-shift image stabilization only, which it calls IBIS ( I n- B ody I mage S tabilization),
365-569: A DSLR-like form factor much similar to the G5 X. It also is the first PowerShot (with the exception of waterproof D-series) to have weather sealing. G3 X is the only superzoom model in the G-series. It offers a 25x zoom (24–600 mm equivalent) with aperture f/2.8-5.6. It offers an alternative to the Canon Powershot SX-series cameras with much better image quality. Because of the lens, the camera

511-663: A commitment to the Micro Four Thirds system. The first Micro Four Thirds system camera was Panasonic Lumix DMC-G1 , which was launched in Japan in October 2008. In April 2009, Panasonic Lumix DMC-GH1 with HD video recording added to it. The first Olympus model, the Olympus PEN E-P1 , was shipped in July 2009. Blackmagic Design sells cameras made for cinematography, some of which use
584-477: A common autofocus system for mirrorless compact or "point-and-shoot" . By comparison, DSLRs use phase-detection autofocus (PDAF). The use of separate PDAF sensors has been favored in DSLR systems because of mirror box and pentaprism design, along with better performance for fast-moving subjects. The (non-Micro) Four Thirds system design standard specifies a 40 mm flange focal length distance, which allowed for using
657-485: A contrast-based system called DFD (Depth from Defocus) until the release of the G9 II in 2023. Both systems today provide focusing speeds to rival or even surpass many current DSLRs. The image sensor of Four Thirds and MFT measures 18 mm × 13.5 mm (22.5 mm diagonal), with an imaging area of 17.3 mm × 13.0 mm (21.63 mm diagonal), comparable to the frame size of 110 film . Its area, ca. 220 mm ,
730-618: A custom grip to make the camera easier to grip, and a plastic ring to surround the control dial, making the dial less likely to be accidentally moved. In the high-end compact camera market, its main competitor is the Panasonic Lumix DMC-LX3 (and the Lumix's sister camera, the Leica D-Lux 4); one significant difference being that the S90 is significantly slimmer due to the fully collapsible lens, hence more portable. The Canon PowerShot S95
803-513: A fast zoom lens, for better shallow depth of field throughout the maximum-aperture range, and sharp shots even in low light, a DIGIC 6 processor with capability to take 1080/60p MP4 video shoots. The camera lacks a built-in viewfinder but supports an external electronic one. It has no microphone input or headphone jack. In October 2017, Canon introduced the third model of the G1 X-series: Canon PowerShot G1 X Mark III. It replaced

#1733085918421876-520: A feature included all of its cameras. Until 2013, Panasonic used lens-based stabilization only, called Mega OIS or Power OIS ( O ptical I mage S tabilization). These stabilize the image by shifting a small optical block within the lens. In 2013, Panasonic began including sensor-based stabilization in its cameras, beginning with the Lumix DMC-GX7. Panasonic called the combination of lens and body stabilization "Dual IS," and this function won an award of
949-408: A few identical image parameters for some popular image sensor classes compared to Micro Four Thirds. The smaller the focal length, the smaller the displacement in the image space between the last principal plane of the lens and the image sensor needed to focus a certain object. Therefore, the energy needed for focusing as well as the appropriate delay for shifting the focusing lens system are shorter,
1022-559: A flange focal distance greater than or marginally less than 20 mm can often be used on MFT bodies via an adapter. While MFT cameras can use many of these "legacy" lenses only with manual focus and manual aperture control mode, hundreds of lenses are available, even those designed for cameras no longer in production. While lens manufacturers seldom publish lens mount specifications, the MFT mount has been reverse-engineered by enthusiasts, with CAD files available. Until 2013, MFT cameras exclusively used contrast-detection autofocus (CDAF),

With the hot-shoe for external flash, the Powershot G series can accept not only compatible flash units but also various connecting cords and wireless triggers. However, the Powershot G series is sensitive to the voltage produced by certain flash units, particularly older designs. Canon recommends that
1168-424: A new model — the G5 X Mark II — that replaced the micro USB port with a USB-C port and offered 4K video recording. The G5 X Mark II also included a new lens and a pop-up electronic viewfinder that required manual operation like on older Sony RX100 models. This update returned the line to a rangefinder-like body shape and emphasized its photography focus, compared to the more vlogging-oriented G7 X line. With
1241-466: A particular non-zoom prime lens is sometimes an option. The throat diameter is about 38 mm, 6 mm less than that of the Four Thirds system. Electrically, MFT uses an 11-contact connector between lens and camera, adding to the nine contacts in the Four Thirds system design specification. Olympus claims full backward compatibility for many of its existing Four Thirds lenses on MFT bodies, using
1314-480: A purpose built adapter with both mechanical and electrical interfaces. The shallow but wide MFT lens mount also allows the use of existing lenses including Leica M , Leica R , and Olympus OM system lenses, via Panasonic and Olympus adapters. Aftermarket adapters include Leica Screw Mount , Contax G , C mount , Arri PL mount, Praktica , Canon, Nikon, and Pentax, amongst others. In fact, almost any still camera, movie or video camera interchangeable lens that has

Micros differ however in being significantly larger (with lens attached), and significantly higher-end, featuring much larger sensors and interchangeable lenses. Canon PowerShot G The Canon PowerShot G is a series of digital cameras introduced by Canon in its PowerShot line in 2000. The G series cameras are Canon's flagship compact models aimed at photography enthusiasts desiring more flexibility than
1460-427: A single lens reflex design, with mirror box and pentaprism. Four Thirds DSLR cameras designed by Olympus and Panasonic initially used exclusively PDAF focusing systems. Olympus then introduced the first live view DSLR camera, which incorporated both traditional DSLR phase focus and also optional contrast detection focus. As a result, newer Four Thirds system lenses were designed both for PDAF and contrast focus. Several of

Therefore, 100% crops from the lenses do not usually represent the same level of pixel-level sharpness as they would on their native formats. Another slight disadvantage of using adapted lenses can be size. By using a 35mm film lens, one would be using a lens that casts an image circle that

The G series has a lithium-ion battery , full manual exposure control, an articulated LCD screen (G7, G9, G10, G15, and G16 have a fixed screen), Raw image format capture (all models except the G7), a lens with a wider maximum aperture than standard PowerShot models, remote capture (except the G11), and faster image processing. The range also includes
1679-450: Is approximately 30% less than the APS-C sensors used in other manufacturers' DSLRs ; it is around 9 times larger than the 1/2.3" sensors typically used in compact digital cameras . The Four Thirds system uses a 4:3 image aspect ratio , like compact digital cameras. In comparison, DSLRs usually adhere to the 3:2 aspect ratio of the traditional 35 mm format. Thus, "Four Thirds" refers to both
1752-406: Is equivalent to a 2.0 crop factor when compared to a 35 mm film (full frame) camera. This means that the field of view of an MFT lens is the same as a full frame lens with twice the focal length. For example, a 50 mm lens on a MFT body would have a field of view equivalent to a 100 mm lens on a full frame camera. For this reason, MFT lenses can be smaller and lighter because to achieve
1825-417: Is far larger than what is required by Micro Four Thirds Sensors. The main disadvantage of using adapted lenses however, is that focus is manual even with natively autofocus lenses. Full metering functionality is maintained however, as are some automated shooting modes (aperture priority). A further disadvantage with some LM and LTM lenses is that lenses with significant rear protrusions simply do not fit inside
1898-613: Is much larger than other G-series cameras - weighing 739 grams. The camera also supports an optional electronic viewfinder: either the EVF-DC1 or the EVF-DC2. The G3 X matches the Sony RX10 III and IV for the longest zoom range available on a large-sensor bridge camera but in a much smaller package than its Sony counterparts. In Q3 2015, Canon introduced the PowerShot G5 X as the successor to
1971-703: Is omitted in the Panasonic Lumix DMC-GF3 design. Similar to Olympus, the LVF1 is usable on high-end Panasonic compact point and shoot cameras, such as the Panasonic Lumix DMC-LX5 . Due to the short native flange distance of the Micro Four Thirds System, the usage of adapted lenses from practically all formats has become widely popular. Because lenses can be used from old and abandoned camera systems, adapted lenses typically represent good value for

Therefore, most adapted glass from the 35mm film era and current DSLR lineups provide effective fields of view varying from normal to extreme telephoto. Wide angles are generally not practical for adapted use from both an image quality and value point of view. Using older adapted lenses on Micro Four Thirds sometimes leads to
2117-510: The Canon PowerShot G16 . The G5 X uses a 1-inch sensor, significantly larger than the G16's 1/1.7" sensor. The G5 X is essentially a G7 X with a built-in electronic viewfinder , whereas the G16 had an optical viewfinder. The G5 X also has a DSLR-like form factor with the viewfinder in the center instead of the rangefinder-like offset viewfinder on the G16. In 2019, the G5 X line was updated with

As of mid-2011, Panasonic G and GH series cameras have built in EVF's, while two of the three GF models are able to use the add-on LVF1 hotshoe EVF. The LVF1 must also plug into a proprietary port built into the camera for power and communication. This proprietary port and the accessory

Because the flange focal distance of Micro Four Thirds cameras are shorter than DSLRs, most lenses are smaller and cheaper. Of particular interest in illustrating this fact are the Panasonic 7–14 mm ultra-wide angle (equivalent to 14–28 mm in

As a consequence, the equivalent exposure indexes (respectively equivalent ISO speeds) are different in order to get the identical shutter speeds (i.e., exposure times) with the same levels of motion blur and image stabilisation . Furthermore, for a given guide number of a photoflash device all systems have the same exposure at the same flash-to-subject distance. The following table shows

The Panasonic G9 II is the first micro four thirds camera from Panasonic which has phase detect autofocus. The much shorter flange focal distance enabled by the removal of the mirror allows normal and wide angle lenses to be significantly smaller because they do not have to use strongly retrofocal designs.

In 2015, DJI released the Zenmuse X5 and X5R, which are gimbal-mounted cameras with a MFT lens mount, as optional upgrades for its Inspire drone line. Both cameras can capture 16MP stills and up to 4K/30fps video using one of four interchangeable lenses, ranging from 12mm to 17mm. In 2016, Xiaoyi introduced

In August 2013, SVS Vistek GmbH in Seefeld, Germany introduced the first high-speed industrial camera with a MFT lens mount, using 4/3" sensors from Truesense Imaging, Inc (formerly Kodak sensors, now part of ON Semiconductor ). The SVS Vistek Evo "Tracer" cameras have resolution-dependent shutter speeds, ranging from 147 frames per second (fps) at 1 megapixel (model evo1050 TR) to 22 fps at 8 megapixels (model evo8051 TR). In 2014, JK Imaging Ltd., which holds

However, unlike Four Thirds, the MFT system design specification does not require lens telecentricity , a parameter which accommodated for the inaccurate sensitivity to off-angle light due to the geometry of the photodetectors of contemporary image sensors. Later improvements in manufacturing capabilities enabled
3285-510: The Micro Four Thirds system (body and lenses) is smaller and lighter. However, their sensors are smaller than full-frame or even APS-C systems . The small lenses do not allow the noise depth-of-field tradeoffs of larger lenses in other systems. Many, but not all Micro Four Thirds cameras use an electronic viewfinder. Resolutions and refresh speeds on these EVF displays were originally compared negatively to optical viewfinders, but today's EVF systems are faster, brighter and much higher resolution than

The 400 mm focal length in Micro Four Thirds has the same angle of view as an 800 mm focal length in full frame cameras. When compared to a full frame camera lens providing a similar angle of view, rather than weighing a few kilograms (several pounds) and generally having a length exceeding 60 cm (24 in) end to end,
3431-852: The PowerShot G9 X as the successor to the Canon PowerShot S120 . Even with the 1-inch sensor, G9 X is similar in size to the S120. The larger sensor necessitated that the zoom range be reduced from 5x to 3x, that is from 24-120 mm to 28-84 mm. With the introduction of the G9 X, the S-series was discontinued. It also meant the end of the use of 1/1.7" (9.5 mm diagonal) sensors in Canon cameras. Higher-end models henceforth used 1-inch (16 mm diagonal) sensors or larger, and whereas other models using 1/2.3" (7.7 mm diagonal) sensors. In 2017 Canon updated

Olympus has four available add-on hotshoe viewfinders. The Olympus VF-1 is an optical viewfinder with an angle of view of 65 degrees, equivalent to the 17mm pancake lens field of view, and was designed primarily for the EP-1. Olympus has since introduced

Canon's removal of RAW shooting support was heavily criticized. DPReview expressed their disappointment with the loss of RAW format, while Luminous Landscape stated that the removal of RAW required too many technical decisions had to be made while shooting instead of during post-processing. RAW support can be enabled on

The primary criticisms, beyond the general limitations of small sensor and small size, are that its ergonomics are lacking, and in particular that the rear dial moves too easily, changing exposure and often ruining photos. To address the ergonomic criticisms, third parties have developed

There are many lenses available. On top of this, a large number of other lenses (even from the analogue film era) can be fitted using an adapter. Different lenses yield greater creative possibilities. However, Micro Four Thirds cameras also tend to be slightly larger, heavier and more expensive than compact cameras. Compared to most digital SLRs ,

In 2016 Canon announced the Canon PowerShot G7 X Mark II which follows the original G7 X. It retains the same sensor and lens as its predecessor. The main improvement is the new DIGIC 7 Processor. In fact the G7 X Mark II is the first Canon camera to use this new chip. This new chip leads to better AF performance, object tracking, reduced ISO noise and higher speed burst shooting. Some other improvements are that

Such a lens, however, would eliminate the room necessary to accommodate the mirror box of the single-lens reflex camera design, and would be incompatible with SLR Four Thirds bodies. Micro Four Thirds reduced

However, the chip diagonal is shorter than 4/3 of an inch; the 4/3 inch designation for this size of sensor dates back to the 1950s and vidicon tubes, when the external diameter of the camera tube was measured, not the active area. The MFT design standard also specifies multiple aspect ratios: 4:3, 3:2, 16:9 (the native HD video format specification), and 1:1 (a square format). With
4891-402: The smaller the focal length is. Micro Four Thirds has several advantages over larger format cameras and lenses: Though many DSLRs also have "live view" functionality, these often function relatively poorly compared to a Micro Four Thirds electronic viewfinder (EVF), which has the following advantages: Olympus and Panasonic approached the implementation of electronic viewfinders in two ways:
4964-499: The specified flange focal distance from 38.67mm to 19.25mm. This reduction facilitates smaller body and lens designs, and enables the use of adapters to fit almost any lens ever made for a camera with a flange distance larger than 19.25mm to a MFT camera body. Still-camera lenses produced by Canon, Leica, Minolta, Nikon, Pentax and Zeiss have all been successfully adapted for MFT use – as well as lenses produced for cinema, e.g. , PL mount or C mount . For comparison of
5037-588: The tables under Fixed Focal Length Lenses, below), and there are certainly many lenses faster than f/4.8 for full frame. Although they can have shallower depth of field than a Nikon 1 at f/1.7, it can be seen as advantageous. However, a further aspect of image resolution is limitation by optical aberration , which can be compensated the better the smaller the focal lengths of a lens is. Lenses designed for mirrorless camera systems such as Nikon 1 or Micro Four Thirds often use image-space telecentric lens designs, which reduce shading and therefore light loss and blurring at
5110-411: The weight up to G12 is for the camera without the battery and from G1 X on the camera including the battery and the memory card. The Powershot G series can employ several photographic accessories: Starting from the G7, there is a bayonet mount on the front of the camera around the lens to directly attach lenses and accessories. Powershot G series cameras have a standard threaded socket for mounting to
5183-485: Was announced and released in 2010. It was designed as the successor to the Canon PowerShot S90. The Canon PowerShot G series (as of June 2010, the G11) are similar in terms of target market, but feature a larger body and slower optics at the wide angle end. A similar category to high-end compact cameras are mirrorless interchangeable lens cameras ("micros"), some of which are in a compact form factor (with
5256-445: Was significant that it did not replace the older G12 but created a parallel model in the first time in G-series. Later that trend would continue with five parallel models from 2015 on. The camera is also bigger and heavier than the other G-series cameras, and the zoom range in equivalent 35 mm is only 28-112 mm (4x). With its maximum aperture over its zoom range being F2.8-5.8, and with its sensor smaller than Canon APS-C sensor,
5329-706: Was the successor to the G12 as the cheaper G series model. It marked a return to a lens faster than those of early G cameras. It also has: The G16 offered only minor improvements over the G15, for example: The G1 X was introduced in February 2012 and is the first large-sensor entry in the series as designated by the "X" after the model number. It is also the first model in the series with a CMOS sensor. The G1 X's sensor measures 18.7 mm × 14.0 mm (1.5 in), which makes it 16 percent larger than Micro Four Thirds (MFT) sensors and 20 percent smaller than Canon's APS-C sensors. G1 X
