Key Features

The Canon Mark III comes with a sensational 22mp full frame CMOS sensor providing it with an incredible resolution. Another selling point for the mark III is the 14-bit DIGIC 5 image processor. That combined with eight-channel readout gives Canon Mark III a shooting power of up to 6fps. Users can now enjoy more storage space with the dual card slot feature for both the CF and the SD.

It has its sensitivity ranging from ISO 100 to 25600 for the standard version and an extended ISO of fifty to 102800. The Mark III brags of the 150000 frames rated shutter. It is also capable of video recording in a 1080p30 resolution as well as stereo sound recording trough an external microphone.

Image Quality and Performance

The ability of the Mark III to fill a subject with 61 autofocus points, cross type in nature, plays a great role in enhancing its shooting accuracy. You can swap between sing AF point to multiple points and at the same time orientate left or right. The Mark III automatic lens correction gives it top performance. The qualities that can be corrected in-camera include darkened corners, corner color fringes, and distortion. Hence, you can save on cost and weight on extra correction lenses.

The DIGIC 5 processor has ensured better start up and incredible processing speeds. It is possible to take over 100 JPEG shots and 15 to 20 images in the Raw Mode. The high ISO performance on the Mark III provides a significant variation in the image texture and resolution. The standard setting produces appealing, vibrant and punchy color. For impressive sharp results, you can integrate it with the Canon EF 24-70 f/2.8 or Canon EF 70-200 f/2.8 zoom lenses.

The HDR function enables consecutive images that can then be blended into a single fantastic image.

Design and Controls

Just like the EOS 7D, the Canon 5D Mark III combines live view or movie control just beside the viewfinder. The power button lies below the mode dial. The build material, magnesium alloy shell, gives it that strong, durable feel. The on and off button is strategically positioned to allow easy accessibility especially when supporting a heavier lens, and also to avoid accidental pressing.

The main control dial behind the shutter changes the primary exposure parameter. The customizable M-Fn dial lies amidst the two and performs functions such as Flash Exposure Lock. Immediately behind this button is a row of 3 knobs which are metering mode, Auto Focus mode and ISO exposure compensation. There exists another button beside them that illuminates the top-plate display.

On the left side of the camera, beside the pentaprism lies the power switch and mode dial buttons. It has the standard modes, which are the program, aperture priority, shutter priority and the manual. The Auto+ mode available offers an array of creative controls based on the image results. The new effects button, multiple exposures, and HDR mode are usually at the bottom of the picture.


The Mark III has the whole package that a professional photographer would require while in practice. They include:

• A very high resolution with an incredible hue and color accuracy.

The remarkable viewfinder experience, in addition to the improved autofocus coverage area, makes it a great camera for professional use. The default settings for auto correction and noise reduction play a significant role of taking raw fantastic JPEG images, also making it a great family or personal camera.


The Mark III was the most awaited camera in its 5D line. It hasn’t disappointed and improved significantly on the weaknesses of its predecessor Mark ii. With the six frames per second and the powerful autofocus system on this camera makes it applicable in a plethora of photography environments.
