The Canon PowerShot G7 X III is the third in a series of 1"-type sensor compacts aimed at smartphone camera upgraders and enthusiast photographers looking for a small second camera. Its core photography features - notably its fast 24-100mm equivalent F1.8-2.8 lens - are very similar to the G7 X II that preceded it, but Canon has given the Mark III a new Stacked CMOS sensor and Digic 8 processor that together promise better image quality and performance.
The biggest changes in the G7 X Mark III are to its suite of video features, which now includes the option to live stream video: a useful feature for vloggers. Resolution has been bumped up to 4K, with 30p available out of the box and 24p coming via a future firmware update.
