The Canon G7 X Mark III takes the features that made its predecessor a solid camera: its fast 24-100mm equiv. lens, very good image quality and tilt-up screen - and tried to make the camera into even more appealing to the vlogging crowd. Canon added support for 4K video with no crop, live streaming over YouTube (a first for any camera), an external mic socket and support for vertical video capture. Video quality is good, though not best-in-class, as long as you stay away from the 'high' image stabilization setting.

Ironically, Canon did disappoint video fans when the G7 X III was released, leaving out 24p capture (pending a promised firmware update) and having a 10 minute recording limit (presumably to reduce overheating). Autofocus doesn't compete with the Sony RX100 VA, its closest competitor, even after a quick firmware update, but it's important to keep in mind that the Sony is considerably more expensive. The live streaming feature does work, but you'll likely be banging your head against the wall trying to get it set up (and actually function reliably once you've done so).

Stepping away from video, the G7 X III feels like a premium camera, with good build quality and subtle yet stylish red accents under its dials. While it lacks an electronic viewfinder (Canon offers the G5 X II if you want one), the tilting LCD is selfie-friendly, and Canon's touch interface is well done. The Mark III continues to offer a built-in ND filter: a nice extra for shooting video outdoors or taking advantage of the lens' capability for shallow depth-of-field.

The camera's Digic 8 processor gave the G7 X III a big speed bump compared to the Mark II, with a 30 fps Raw burst mode (with AF locked) and 8.3 fps with continuous AF. The autofocus system is responsive when shooting stills, and it can track subjects fairly well, but you can't use continuous tracking AF and burst mode at the same time, which is disappointing. Something that didn't get a bump is battery life, which is about average. While the camera can charge over its USB Type-C port, it only supports chargers and power banks that support USB Power Delivery.

Taken as a whole, the PowerShot G7 X Mark III is a very good camera. As a stills camera, it's one of the best enthusiast compacts on the market, and a good value considering its feature set. Its video specs are impressive, though its autofocus and video recording limit are not. The lack of 24p support is frustrating, but at least it's being added very soon. It's not a product we're jumping up and down about, but it still earns our recommendation.

Compared to its peers

Sony Cyber-shot DSC-RX100 VA - The closest competitor to the G7 X III offers a superior autofocus system, and its ability to shoot 24 fps bursts with continuous autofocus is amazing. Its pop-up EVF is great for when you're shooting in bright outdoor light. The RX's lens doesn't have as much reach as the G7 X III's, it lacks a touchscreen, and battery life is poor. It's also considerably more expensive.

Canon PowerShot G5 X Mark II - The G5 X II sacrifices live video streaming and a mic input for a longer lens (that tops out at 120mm equiv., compared to 100mm) and a pop-up EVF. If you don't need those video features and can spend a bit more, then we think these extra features make the G5 X II is the better choice.

Panasonic Lumix DMC-LX10 - The lens on the LX10 is slightly faster at wide-angle than that of the G7 X III (F1.4 vs F1.8), and its focal range is about the same. It handles well and also has a flip-up LCD, and can produce attractive images, though JPEG image quality is a step behind the Canon. It also has a very small buffer and an AF system that likes to hunt, especially in video. Based on that, we give the G7 X III the edge.

The Canon PowerShot G7 X III is a compact, well-priced camera which offers very good image quality, a fast lens, good ergonomics and the ability to stream live video straight to YouTube. Its lens isn't super-sharp at wide-angle, video autofocus is so-so, and live streaming is difficult to get working, but overall, it's a good value for the money and well worth considering.
Good for
Those seeking a pocketable camera with a versatile lens that will perform better in low light than a typical compact. Vloggers.
Not so good for
Action and landscape photographers. Those who want an EVF for shooting outdoors.
