Samsung NX mini review – Autofocus
Unfortunately, the NX mini doesn’t feature the on-chip phase-detection autofocus we saw in its slightly bigger brother, the NX300. Instead, it is contrast method only for the mini’s 21 AF points in standard mode, or 35 points in close-up mode. In good light the AF performed well, though, focusing quickly the majority of the time.
However, on a number of occasions the camera would capture entirely blurred frames, particularly when taking self-portraits; for no apparent reason, the camera would acquire focus and then just before taking the shot it would hunt, lose focus and then trigger. I didn’t miss any critical images due to this quirk, but it’s still a concern.
Tracking and shooting fast-moving subjects is a little better, thanks in part to the ability to track subjects by touching the screen and the camera’s super-fast maximum shutter speed of 1/16,000sec, and raw+JPEG shooting at up to 6 frames per second, so it’s possible to freeze fast-moving subjects well, provided you’ve got good light.
