I haven't been using my camera very much over the past few months. The few times I've pulled it out, I noticed that the autofocus doesn't work when I put on my 35mm prime. I tested my 55-200mm and 18-55mm and their autofocus works. I have made sure that both the camera and lens are set to AF. I cleaned off the lens contacts with a cloth and isopropyl alcohol.
Is my only option at this point getting it refurbished? I'm not sure I have a warranty still; the lens was bought in November of 2012 but I didn't register it until October 2014.
Thanks for any help or advice!
