I recently got my D7100 back from Nikon repair (the auto-focus had stopped working).  The auto focus is now working, better when I take shots indoors, but not-so-much outdoors.  My main subject matter is birds.   I've shot 3000 outdoor photos in the last two weeks, and maybe got 20 pics that were just ok.  These few pics are still off and lack sharp details.  All the others are so blurry I'm getting a headache looking at them.  The indoor photos are better, but still not all perfect.  I even tried some test photos of a focus calibration form, they seemed much better.  I've also noticed a marked difference between photos taken in aperture priority and program modes.  The program mode shots are slightly clearer.

I talked with Nikon and they asked me to send some photos in.  And now I wait for an answer.....

In the mean time - I thought I'd look for some input from my friends here in the Nikon Forums.

Specs - D7100, 300mm f2/8, mounted on a tri-pod

Thanks for your expertise and input!!!

Do you ever calibrate your long lens?  How often? What equipment do you use to calibrate?

I use my 300mm f2.8 to photograph birds, and sometimes feel the images could be just a little sharper.  I've read about calibration on some websites, and look forward to more input.

Thanks!

Hello from Geneva, Illinois, USA!!!

I've been looking around this new Nikon Forums site, and am very excited to have a place to share my Nikon enthusiasm.  

I'm an avid bird and nature photographer, using my Nikon D7100 with a 300mm f2.8 to capture the joy's that I find in the gift of the outdoors.  Feel free to visit my website http://www.naturesjoyphotography.com to view and comment on my photos.
