Sony NEX-3N review – Autofocus
The NEX-3N’s autofocus is fast enough for most conditions, although there is a slight shift as the lens moves back and forth to determine correct focus, which means it’s not quite as instantaneous as some other compact system cameras. Focus in low light is aided by an AF assist lamp, which is bright enough to take care of most tricky situations, and although the object tracking function doesn’t actually continually focus on the subject – instead, tracking its movement before focus is initiated by the user – the camera does well to stay with the subject as it moves around the scene.
