How often do you make fine autofocus adjustments with D600? both 35mm and 50mm needed it

My 50mm 1.8G is sharp on my D600 at all distances except close to its minimum focusing distance.

Then it requires -15.

I have had my 50mm 1.4G calibrated on my old D7000 and they got the focus 100% spot on at shorter distances, but it was not as sharp at more distant subjects. You need to decide how you are using the lens and have it calibrated accordingly.

For now, I just turn on the focus adjustment when I shoot close up.
