Df worse AF than d600/610?
Dec 20, 2013


"Something we've noticed when shooting in very low-light conditions is that focus acquisition is much more successful when using the central AF points. We've consistently seen instances where the AF points in the central 3 x 3 grid can lock focus quickly, yet attempting to focus on the same subject with outer AF points leads to focus hunt and ultimately a failure to confirm focus at all. We stress that this is limited to very low light situations and it's certainly not unreasonable to expect improved AF performance towards the center of the array. Shooters who work often in low light should be aware, however, that there are conditions under which these outer AF points will be of little practical use."


"Df's focus drops off significantly at even moderate indoor lighting levels. Even at an illumination level of around 4.5EV, we've found the camera has to 'hunt' to find focus, and the only reliable way of getting a shot was to use the central focus point to focus-and-recompose from a high-contrast point."

According to the Df review AF issues already occur at EV 4.5. And whereas the d600 performs properly in low light with 9 central sensors and only fails with outer AF points in very low light situations, the Df has to revert to the central focus sensor and still has problems.

So what did Nikon do to get such a bad AF judgement? Did they test a bad one ?
