Autofocus
Although I have no complaints about the G10’s AF performance with stationary and slow-moving subjects, its contrast-detection system is not ideally suited to shooting sport or fast action.
When photographing one of the Race for Life events, for example, there were a few occasions when the camera failed to focus the lens before the subject had passed me. Walkers didn’t trouble it, but I found it was hit and miss with runners.
The AF Tracking mode is useful with fairly slow-moving subjects, or for using the focus and then compose technique, but it failed to latch onto any of the runners as they headed towards me in the race.
