I just picked up a D810 and I’m finding that the AF Fine Tune on my lenses seems to be requiring corrections of +/- 20 points. This seems… extreme? Has anyone else been experiencing this with their Nikons? I also had this experience on my D610.
My current method for fine tuning is placing a ruler on a flat table, focusing on a number with the number as close to the middle of the single focus point in the middle of the frame. Take three shots with defocusing between each one and then evaluating the focus at 100% on my viewfinder.
I feel confident in my technique but such an adjustment makes me feel like something is up. Anyone else running into this?
