The Canon PowerShot G1 X Mark III is a camera that leaves me with very mixed feelings. It puts an APS-C sensor and zoom lens into a form factor we haven't seen before-one that's pocketable-and both the lens and sensor are quite good.

Big, APS-C image sensor; Compact body; Dual Pixel AF; EVF; Vari-angle touch LCD; Dust and moisture resistant

Expensive; Short, narrow aperture zoom lens; Disappointing battery life; Eye sensor active with LCD away from body; Video limited to 1080p

Canon's G1 X Mark II was almost a great camera. It had a solid, wide aperture zoom lens, paired with a bigger sensor than competing models. But there was no built-in EVF, and its 13MP image sensor didn't offer as much resolution as competitors like the Sony RX100 III. Its replacement, the G1 X Mark III ($1,299), ups the sensor size to APS-C, the same as you get in an SLR, while at the same time sizing down the body. But it comes at the cost of zoom range—the Mark II's 24-120mm f/2-3.9 zoom has been replaced by a shorter 24-70mm f/2.8-5.6 lens. Image quality is strong, but I question its value and place in the Canon line, especially when the G5 X delivers a longer zoom range with a brighter lens for a lot less money, albeit it with a smaller image sensor. Design and Features The big selling point of the the G1 X Mark III ($999.00 at Amazon) is its size. It's just a little bit bit bigger all around than the G5 X, which has a smaller 1-inch sensor and boasts an almost identical desig...

The Canon PowerShot G1 X Mark III is the smallest zooming APS-C camera we've seen, but it feels like a step back from the Mark II.

Advanced bridge cameras such as the Canon PowerShot G1 X Mark III ($1,299) can make great travel companions, because they have large image sensors and high-quality optical-zoom lenses.

Compact and lightweight; Very good for travel; Offers many scene modes; Excellent in low light and challenging lighting; Responsive swiveling touch screen

Lacks 4K video recording; Only 3x optical zoom; Slightly less versatile than other high-end bridge cameras; Very pricey for its class

The G1 X Mark III is an impressively compact camera with a large APS-C sensor and a zoom lens with a versatile focal range. It has tons of direct controls and can produce great image quality, but is expensive and the permanently attached lens has a slow aperture range and hampers an otherwise capable, pocketable camera.

General photography, landscapes and world travelers who don't mind bringing along an extra battery or two.;

Those who want to be able to photograph sports or work primarily in low light.;

With budget compacts more or less killed off by the ever-advancing phone camera, dedicated cameras play a very different role these days. And as not everyone wants to lug around a massive lump, mirrorless and DSLR cameras simply won't suit all photographers all of the time.

It's so small considering the sensor size; great image quality from APS-C size sensor; Dual Pixel AF is a capable autofocus system; built-in EVF and vari-angle toucshcreen controls; solid dust/drip-proof construction

Maximum aperture quickly drops to f/5.6 which is limiting; zoom could be snappier through the range; autofocus won't rival a DSLR; it's obviosuly expensive

Canon's PowerShot G1 X Mark III exists in somewhat of a vacuum. It has a large APS-C sized sensor, is small enough to be considered pocketable, and has a permanently attached zoom lens with a versatile focal range.

I'm upgrading my original G1X and this camera has fixed all my little issues with it. The G1X3 has a very sharp lens, as good or better than my G1X or 15-85. I compared the G1X3 at the wide end with my 16-35f4L and 24-105f4L at 24mm on my 5D3 and found it equally sharp in the center andclose to the...

The Canon Powershot G1 X Mark III has taken the great usability of a Canon DSLR, and the 24mp APS-C CMOS sensor with phase-detection AF built-in, and squished it into a compact camera, whilst maintaining excellent handling and usability.

24mp APS-C CMOS sensor in a compact camera; Excellent noise performance for class; 3x optical zoom lens with f/2.8 aperture; 3inch vari-angle touch-screen; A number of control wheels; Compact for the size of sensor; Auto Panoramic mode!

FullHD video - no 4K or high-speed video; Short battery life (200-250)

What Canon has done with the G1X Mark III is pretty remarkable. Although there are lots of compromises, having an (almost) DSLR in your pocket is pretty damn cool. It would make the ideal travel companion, for somebody who craves all the manual control, RAW format shooting and large sensor image quality that a camera like this brings, without being bogged down with a bulky DSLR. In fact, even the smallest compact system cameras are generally bigger than the G1X Mark III. Of course, you do pay a pretty penny for this miniaturisation, making it unlikely to be the camera of choice for those on a tight budget. In short - this isn’t a camera that lets you abandon your DSLR completely, but it’s a very good backup for shooting on the go.
