The new PowerShot G1 X Mark III is the first Canon point-and-shoot to feature a larger APS-C CMOS sensor with DIGIC 7 Image Processor and Dual Pixel technology.

Upgrading to the larger APS-C sensor is a smart move as it allows Canon to offer a lot of the same technologies normally found in their more recent non full-frame DSLRs in a pocket sized body.

PowerShot G1 X Mark III Features

As mentioned, the G1 X Mark III features a 24.3-megapixel APS-C CMOS sensor and Dual Pixel CMOS AF system which Canon states is “popular amongst enthusiast and professional users, provides extremely fast and smooth autofocus capabilities across nearly the entire focal plane, allowing for more creative compositions when framing a subject away from the center of a shot.

The first Canon compact digital camera to feature a large 24.2 Megapixel APS-C sensor for detailed images and Dual Pixel CMOS AF for fast autofocus.

The lens is a wide-angle 24-72mm (3 x Zoom) with Optical Image Stabilization and a wide f/2.8-5.6 aperture range providing “maximum brightness and increased sharpness in images”, and the ISO range of 100 – 25,600 provides lots of versatility to shoot in low-light situations.

Continuous shooting speed is up to 9fps when shooting with the Dual Pixel system and fixed AF and 7fps otherwise.

The G1 X Mark III will also capture 1080p/60p HD video in MP4, MPEG-4 AVC/H.264 formats.


The back of the camera features a 2.36-million -dot OLED electronic viewfinder (EVF) and a 3-inch vari-angle touchscreen LCD which provides touch and drag AF control when composing and shooting without having to take your eyes away from the EVF.
