Autofocus

Contrast-detection AF on the Sony NEX-F3 gives accurate and fairly speedy focusing. The focus tracking also performs well, keeping locked on to a chosen subject as it moves around the frame. There are options for single, continuous, multi and centre focusing, although the flexible spot option gives most control with 187 positions available in the frame. Close focusing can still be a little slow, however, and low-light usage still isn’t quite up to phase-detection standards.
