Over the last five years Canon has been refining its G7 X series, cumulating in the third release in the series: the G7 X Mark III. This latest model continues the form set by its two predecessors, pairing an all-new 1-inch sensor - which is larger than typical in most cameras, designed for better image quality - with a tried-and-tested 24-100mm zoom lens.
But where the G7 X III differs compared to its previous duo is with the introduction of a 3.5mm microphone input. Because Canon has the vlogging community in its sights with this camera; a niche yet sensible move given the camera's flip-forward self-facing screen feature to make recording - even in 4K Ultra-HD quality - a cinch.
G7 X 3: What's new?
New stacked construction CMOS sensor
Adds 3.5mm mic jack and 4K video
EOS-like menu system
Unlike the G5 X II, which is announced in tandem, the G7 X III doesn't really change the base make-up of what it's all about. The Mark III has the same footprint, screen, lens and physical layout of the Mark II model from before it. There is new DSLR-style menu system, though, which will feel familiar to Canon users looking for a pocketable carry-around camera.

Where the G7 X III really differs is in two key areas, which we've already touched upon: the introduction of a new 20.1-megapixel CMOS sensor, which has a stacked construction rather than back-side illuminated form, said to allow for cleaner signal and better quality than before; and the arrival of that 3.5mm microphone input jack, which makes recording audio via a wired or wireless mic pickup far easier when capturing those (also new) 4K Ultra-HD clips.
