IMAGE QUALITY & PERFORMANCE - CANON POWERSHOT G3 X
In terms of speed and responsiveness, the PowerShot G3 X felt like it was somewhere in between the Nikon and the Panasonic cameras. Still responsive enough in practice; but not quite the fastest. The camera was fairly fast to respond without too much lag between shots, but we did find ourselves a little frustrated by the implementation of the autofocus system. Despite having 31 contrast-detect autofocus points across the frame, the PowerShot G3 X only offers two methods of autofocus – face detect with subject tracking and one-point, neither of which offer the flexibility needed of a bridge camera. The major saving grace though, is the much larger 1-inch sensor, as it allows the camera to produce images with less noise and better details than the other two, while turning in the best high ISO performance. We’d use images taken at ISO levels up to 3,200 without hesitation, and ISO 6,400 should be usable for prints after some sharpening in post.
