Nikon D610 review – Autofocus
The D610 sports a generous 39-point AF system, with the Multi-CAM 4800 unit featuring nine cross-type variants at the centre for improved AF acquirement while the system is also locking onto your subject in conditions as poor as -1EV. Not only that, but because the AF system is hooked up to the D610’s scene-recognition system, 3D focus tracking is possible – which sees the D610 utilise a predictive system to track your subject as it moves round the frame.
Peering through the viewfinder, it is disappointing to see the AF points grouped relatively closely together in the centre of the frame, although that’s the only major issue here. The D610’s AF will, in most situations, lock on quickly without any hunting – even in relatively poorly lit conditions.
Selecting the AF point is done via the D-pad at the rear. In some situations it might be desirable to reduce the active AF points to 11 to enable quicker movement around the frame.
It must be said that the sophisticated AF tracking options at your disposal when AF is set to continuous work impressively well. Of course, you’ll have to spend a little time learning the system – there’s a choice of nine, 21 or 39-point dynamic AF modes on top of the 3D tracking mode, but the set-up that’s most appropriate for you will depend on how erratically your subject is moving.
