Canon Powershot G7 X Mark II Performance

The performance section is where we look at the image quality performance of the camera. Additional sample photos and product shots are available in the Equipment Database, where you can add your own review, photos and product ratings.

Speed - We took a number of shots to test the camera's responsiveness, from switch on to first photo, shot to shot, focusing speed etc. We take a number of shots and then use the average to ensure accurate and consistent tests, making it easy to compare with other cameras.

Shutter Response <0.05secs
Wide - Focus / Shutter Response 0.125secs
Full zoom - Focus / Shutter Response  0.125secs
Switch on Time to Taking a Photo 2.0secs
Shot to Shot without Flash 0.6secs
Shot to Shot with Flash 3.1secs
Continuous Shooting - JPEG
(shots before slow down)
8fps (30 shots*)
Continuous Shooting - Flash 2.9secs
Continuous Shooting - RAW 8fps (21 shots**)


Focus and shutter response are both fast, and slightly faster than the G7 X the camera replaces. It's possible to shoot up to 30 shots in continuous shooting mode, at 8fps when shooting JPEG images, and we managed to shoot 21 shots when shooting raw, although the camera then took 23 seconds to clear the image buffer before we could review the images. *Before slowdown, **before stopping.

Canon PowerShot G7 X Mark II Sample Photos

Sample Photos - Portrait photos taken with flash show no signs of red-eye, and skin tones are very good. The camera is capable of producing images with excellent colour, that is pleasingly bright and punchy without being overly saturated. Exposure is reliable, without much need for the exposure compensation dial. You can expand the dynamic range captured by the camera by using Canon's Auto Lighting Optimiser (ALO), without having to resort to the HDR shooting mode, which takes a number of shots and combines them into one. 

Canon PowerShot G7 X Mark II Lens test images

Lens Performance - Detail is very good overall, excellent in the centre of the frame, and remains good into the corners, even when shooting wide-angle shots. The lens also performs well at the telephoto end of the lens. The macro performance of the lens is good, being able to focus on subjects that are 5cm away from the lens when shooting wide-angle, and the ability to shoot close up shots at the telephoto end means you can get images with pleasing background blur. There were no real issues with vignetting, and it was difficult to spot any signs of chromatic aberrations or purple fringing. The lens was also quite resistant to flare, even when we tried to specifically create flare, there was little to be seen. 

Canon PowerShot G7 X Mark II ISO test images

ISO Noise Performance - Noise is very low, and detail very good at ISO125, and ISO200 with a slight drop in detail at ISO400 (although with low noise), and the same happens at ISO800. At ISO1600 there's a slightly more noticeable drop in detail, and a slight increase in noise, although results are still good. At ISO3200 there's another increase in noise, and a slight drop in colour saturation. It's not till ISO6400 that you really need to worry about noise though, although at this ISO speed images may still be usable. ISO12800 shows the highest levels of noise, and this setting is best avoided. The G7 X Mark II gives slightly improved noise performance when compared to the G7 X. You can adjust the High ISO speed NR (Noise Reduction options), the options are low, standard and high, and we left the camera on the default setting of standard. 

Canon PowerShot G7 X Mark II White-balance test images

White Balance Performance - Auto White Balance (AWB) performs well under tungsten lighting with a slightly warm result, and the tungsten preset gives a more accurate, and whiter result. AWB performs very well under fluorescent light, with the fluorescent preset giving a slight colour cast. AWB performs very well under mixed lighting conditions. 

Canon PowerShot G7 X Mark II Digital filters

Digital Filters - There are a number of scene modes including HDR, Fisheye, Art Bold, Water painting, Miniature, Toy Camera, Background defocus, Soft focus, Grainy B&W, Underwater, Fireworks, Portrait, Panning, Star, and Handheld nightscene. We've shown examples of a number of these above. 

Video -  Video quality is good with the camera recording FullHD 1080p at 60fps, with stereo sound, and optical zoom is available while recording. You can use the touch screen to set the focus point while recording, and the ability to set the front control ring to be "clickless" means that you can adjust settings or change the zoom silently during video recording. Audio quality is good and there was little noise from the lens when zooming or focusing.

I cannot understand how anyone, particularly those of us who also have a DSLR, would choose the G7X, whether mark I or II, over the G5X. The latter has a view finder, unusual on Canon 'point and shoot' cameras, but a very welcome addition.The lens is the same in both.
