Canon’s latest enthusiast compact offers a compelling combination of a long zoom range and a relatively large 1in sensor. Andy Westlake tests it out

Canon PowerShot G3 X review – Autofocus

The G3 X's AF system struggles with fast moving subjects, but gets a few shots in focus

The G3 X’s AF system struggles with fast moving subjects, but gets a few shots in focus

In good light, the G3 X focuses quickly, decisively and accurately, just as we’d expect to see from a modern contrast-detection system. As light levels fall, though, the autofocus becomes progressively slower, especially at longer focal lengths with their slow maximum apertures, taking up to a second to acquire focus in just moderately low light. This means that the G3 X isn’t necessarily a great choice for shooting indoors in poorly lit interiors.

Continuous focusing isn’t particularly great, either. With no phase-detection elements to help it out, the G3 X is no match for either DSLRs or recent CSCs. This negates some – although not all – of the advantage of having such a long lens in a relatively small package. For example, shooting at an airshow I got relatively few shots in really sharp focus. Of course, you can always revert to manual focus in some situations, aided by a peaking display and magnified view. But again, the slow maximum aperture of the lens means that the live-view feed gets rather noisy in only moderately low light.
