The following are ISO samples from the Canon Canon PowerShot G1 X Mark II. In case you missed the press release, these are the pertinent specs:
- Multi-aspect ratio 12.8 megapixel 1.5-inch CMOS sensor
- f/2.0 -f/3.9 maximum apertures
- 35mm film equivalent focal length: 24-120mm
The second generation G1 X blurs the lines between the advanced compact and mirrorless category; it's built like the former but has image quality and a feature set to rival the latter.
The following is an ad hoc set of ISO samples using the pop refrigerators across from the camera store, using default JPEG settings out-of-camera, This test isn't directly comparable with other camera test done on this blog because of variable lighting conditions and differences in camera positioning, but it should give you an idea of how the camera performs as the ISO increases. Watch for noise in the broad colour patches, the definition in the bottles, as well as the harshness of the shadows and reflections. These were shot at f/3.2, at 24mm equiv focal length; crops are taken from middle left of the frame.

Note: The ISO 12800 image is exposed 1 EV above the other samples, as the camera (Av) mode chose the same shutter speed (1/2500s) as in the ISO 6400 shot. Maximum shutter speed in (M) or (Tv) mode is 1/4000s,
To be honest, the lens sharpness is disappointing. These shots are spot-focused from roughly the middle left of the frame, and stopped down. The folks at PC Magazine have noted the same with off-center image quality and at widest-zoom. However, one factor that may be playing into the subjective perception of sharpness is that we are used to seeing large-sensor cameras with higher pixel counts. The G1 X Mark II's EOS Rebel siblings are at 18mp, and the rival Sony RX 100 M2 is at 20mp.
There will be more to say about these samples... as well as about the overall camera itself... in the coming days.
