lens calibration (Page 2): Where are you trying to find infinity? Infinity is not necessarily at the point that is turned fully around. It is not at the same spot on every lens. Here...

Where are you trying to find infinity?

Here is a boring little film that explains it quite well.
You can skip the first 1 min 40 secs.

Was your focus indicator displayed when you photographed the moon?

This is one reason I will need to move up from the D5200 eventually. Can't believe that you need a better body to calibrate focus. Live and learn. I feel a case of G.A.S. coming on fast!

Sorry, but focus calibration is a pro level feature.
Your D5200 is definitely NOT pro level.
You need a recent 1 or 3 digit model number for pro features.

Actually, the Nikon D7100 has a database of lens adjusts also. the D5300 and below do not.
In the D7100, If I am reading the question correctly, it is in the AF fine tune under setup.

And I can save up to 9 non-cpu lens datas.
Not sure if that is what you were referencing or not.

You're correct, I forgot about that model.
And I DID say 'recent', since my D200's and D2Xs don't have it either.

LOL. I was afraid I was confused and didn't want to steer anyone wrong. And, I was afraid to do too much experimenting on mine. If it aint broke, don't fix it. I did change the auto focus to back AE/L AF/L button and now I keep forgetting to press it to focus.. figures.. when I remember it works great. When I forget. it doesn't focus at all.. grrrrr.
And I keep arguing with people that say that the D7100 isn't considered a "Pro-Am" camera. Nikon does but "pure-shooters" don't. Although, I know a number of Pro's that carry it for the 1.5 and 2.0 "crop/extension".

Looks like atmospheric interference. You should be using live view autofocus for accurate focus. The shutter speed if at least 1/500 should not be an issue. Try again, and process carefully.

I had 3 of my primary lenses calibrated to my camera at a cost of $28.50 per lens. My favorite lens (70-200 f/2.8) was set to -4 and I am quite happy with the results. Good luck.

I agree with Gene. Looks like atmosphere to me. I've found that in summer with humidity levels high, the atmosphere is full of water. I usually get much better results photographing the moon in winter time on a clear night.

David, has the adjustment affected focus at other distances/zoom levels? Was it done by the camera manufacturer?
