The G9 X has the same 20.2 MP 1 inch type back illuminated CMOS sensor as the PowerShot G7 X, which impressed us when we tested it back in 2014. Once again this sensor is coupled with Canon’s Digic 6 processor and this combination enables a sensitivity range of ISO 125-12,800. the G9 X has a 3x zoom lens with a focal length range equivalent to 28 84-mm and a maximum aperture range of f/2-4.9.
The smaller maximum aperture will also mean that it will not be quite so easy to soften backgrounds and shutter speed will drop further in low light so you need to take care to avoid blur. Thankfully the lens based image stabilization system will help with this, offering a claimed 3EV of compensation.
The G9 X is very similar to the G7 X but Canon has managed to shrink it down by 25% and it’s actually very similar in size to the popular Canon S120, which has a much smaller 1/1.7-inch sensor. While this shrinking has had a negative impact upon the lens specification.
Control wise the G9 X is very straightforward. On the top-plate there’s a mode dial for setting the exposure mode, which gives a quick route to aperture priority, shutter priority, program and manual mode, along with options to access fully automatic and scene modes.
There is a ring around the lens on the front of the camera to adjust key settings and a spring lever around the shutter release to zoom the lens in and out. The G9 X are very good; the lens focuses quickly even in low light, exposure seems accurate and colors pleasant. As it has the same sensor and processing engine as the G7 X we can also be moderately confident that images will have a good level of detail and noise that is controlled well.
