To bring theup to date for 2017, Canon gave the Mark II the latest version of its imaging engine, Digic 7, plus improved wireless connection options.
Canon plans to ship the G9 X Mark II in February for $530. (We don't have UK or Australian pricing, but that converts directly to about £430 and AU$730.)
Digic 7 arrived in the G7 X Mark II last year, and in the G9 X M2 it brings a variety of small improvements to the camera. They include better automatic scene detection and Picture Styles, tracking autofocus, image stabilization and low-light photo quality. You'll also be able to shift exposures while shooting time lapse movies.
The other addition is low-energy Bluetooth for maintaining a persistent connection to devices, the first time it's been implemented in a Canon camera (everyone else has had it for a while).
