Canon 5D Mark III has a new DIGIC V + processor, which is 17 times faster than the processor installed in the previous model. This made it possible to apply algorithms for correcting chromatic aberration (only for shooting in JPEG) and suppressing moire, and also to increase the speed of serial shooting.

No less impressive changes have been made to the autofocus system. The 9-point system of the 5D Mark II looked very modest even at the time of presentation, and this fact exacerbated the output of the Canon 7D model with 19-point autofocus. Of course, there was a need for serious improvement and the novelty did not disappoint. The manufacturer installed a block with 61 sensors. Exactly the same unit is located in the flagship EOS-1D X. The only difference is that 1D X additionally uses information from the 100,000-zone exposure metering system to operate the AF system and track objects. There is no such system in 5D Mark III, just as there is no DIGIC IV processor specially dedicated for working with autofocus. However, the autofocus of the Canon 5D Mark III is also very powerful (one of the best).

The illustration below shows the 5D Mark III AF unit. Light streaks are photosensitive areas. During the focusing process using the mounted lens, the pattern of these stripes intersects, is combined and forms the same template with 61 sensors – for a more detailed discussion of the system, see the “Autofocus system” section.

The mechanism for raising the mirror and shutter has been completely redesigned (however, despite the increased speed of burst shooting, the specification still says about 150 thousand operations). Updated mechanics provide a more accurate return of the auxiliary mirror (which sends part of the rays down to the AF sensor), this improves the quality of autofocus when shooting continuously.

In addition to the AF unit, the Canon 5D Mark III borrowed a “silent shutter” mode from the flagship 1D X, which allows you to take single shots or take continuous shots with a noticeable reduction in noise produced by mirror movements and the shutter — a useful mode for situations where it is desirable to maintain silence.

Controls and Design

The chassis is made of magnesium alloy. The camera body has a waterproof design. Thanks to the high-quality exterior, the Canon EOS 5D Mark III looks like a reliable and solid tool. Despite the fair weight, the camera lies perfectly in the hand and does not tire even after many hours of work. However, when installing the battery grip, telephoto lens and flash, everything can change.

On the handle is the receiver window of the remote control system. Between the window and the lens – there is an indicator of the timer for automatic descent. The 5D Mark III does not have an AF backlight. The button under the right hand (near the bayonet mount) enables a preview of the depth of field. Above the EOS 5D logo you can see the holes under which there is a monaural microphone (the interface for connecting an external stereo microphone is located on the left side of the camera in the common connector block).

Since we are talking about connectors, it is worth emphasizing that Mark III provides surprisingly rich opportunities for communication with the outside world.

On the right side of the microphone jack is a jack for connecting stereo headphones (both connectors are standard 3.5 mm mini-jacks). On the left, the PC-sync connector for controlling studio flashes and the interface for connecting a wired remote control found their place. On the right you can see the combined AV / USB connector, as well as a mini-HDMI connector.

The lid of the communication compartment is made of rubber (it closes tightly and confidently).

The Canon 5D Mark III has no built-in flash – quite a standard situation for high-end cameras. As a result, the Canon EOS 5D Mark III cannot control third-party flashes without a wired connection – you need to either use transmitters or install an external on-camera flash.

The new version of the most popular professional camera from Canon. The fourth generation was equipped with a 30 megapixel sensor, and the display became touch-sensitive and in its characteristics is similar to the screen of the older model Canon 1DX Mark II. The electronic filling of the camera allows you to shoot 4K video, and the shutter provides a continuous shooting speed of up to 7 frames per second.

The focusing sensor is equipped with a 61st point, which are evenly distributed over the frame area. The dual slot allows the use of CompactFlash and Secure Digital memory cards. To communicate with a computer, USB 3.0 or the built-in Wi-Fi module is used. The hull and control system have also undergone changes.

The sensor of this camera can process ISO values ​​from 100 to 32000, and in enhanced mode, this range expands to ISO 50-102400. Thanks to the use of a very high-quality matrix with large physical dimensions, the camera forms a low-noise picture even at high ISO values.

A powerful DIGIC 6+ graphics processor in tandem with a proprietary shutter allows you to take photos at up to 7 frames per second. Exposure is measured using an RGB sensor with a resolution of 150,000 pixels and an infrared sensor, which provides additional accuracy when evaluating scenes with complex lighting.

In video mode, support for 4K shooting in the resolution of 4096 x 2160 and a frequency of 30 frames per second is implemented, with the subsequent possibility of using the video sequence for taking photos with a resolution of 8.8 MP. The updated automatic focus system provides the photographer with 61 points, of which 41 are cross-type. The camera focuses equally effectively when taking photos and videos.

The camera is equipped with a 3.2-inch display with a resolution of 1620000 pixels. The touchscreen function allows you to not only work efficiently in the camera menu, but also to focus using the touch of a finger.

The ergonomics of the new case has been substantially redesigned, according to the manufacturer, the camera has become much stronger and more resistant to difficult weather conditions. Additional features and ease of communication are provided by the built-in Wi-Fi (NFC) and GPS modules.
