Suddenly a lens stops auto-focusing
Earlier today my 35 1.8 stopped autofocusing with my D7000. It was working fine for a bunch of shots, I put it in my bag, then when I brought it out again an hour later it had stopped. I took the lens off, put it back on, took the battery out, etc etc but nothing seems to help.
I put the 35 1.8 on my D90 when I got home and it worked perfectly. I put my 24-70 and 50 1.4 on my D7000 and both also worked perfectly. I tried the 35 on my D7000 again and it still didnt work.
Any suggestions on what might be wrong, or how to fix it?
