I received my D7000 with the first batch of body-only shipments. I bought a 32GB Kingston Class 10 memory card to shoot on, and I could take photos fine until one time when I tried plugging the camera into my iMac. The camera files would not show up and the files were unreadable. I formatted the card and it seemed to be fine after that...
I then bought a 16GB class 10 patriot card and after shooting with both for a bit (dual slot set to backup onto 16GB), I couldn't view the photos on the camera! Pressing the playback button just displayed a "Unrecognizeable file" sign. Then the camera would lag and not respond to my pressing the shuttter button or cycling through photos. Trying to turn off the camera also did not work (ie. turning to the off switch did not shut down the camera, it still displayed camera settings on the top LCD).
I've also noticed that switching to Live view Mode takes about 2 seconds now, vs near instant.... Anyone experienced these problems? Seems like the camera is lagging or overloaded and can't process fast enough...
Please Help!
