I thought I'd bring this to your attention since I have no idea what the problem with my camera is and I've never heard of this problem before. My D90 is still in very good condition and I've never had any issues with it at all. Well, I rented a 70-200VR from the local camera shop and it works however I was having some issues with it. One main one is the camera had difficulty reading the lens and every once in a while it kept on giving me an error or f-- message. Also, the camera's shutter would randomly close on me like it was trying to go into Live View mode and I had to turn off the camera to get it back to normal. I tried using my other two lenses, my 18-200VR and my 10.5mm, and I didn't have any issues whatsoever, it was only with the rented 70-200VR. I went back to the shop and explained the problem, and the rental guy said it was a brand new lens, and we tested it on the shop's D700 and D90 and it seemed to work fine, so I'm still really confused what the problem is. One of the shoppers said it could just be a contact error which was causing the camera to freak out, but I just want to get some other opinions and see if this has happened to anyone else before. Thanks for your time.
