Getting an r12 reading on my nikon d300 and it wont focus

Answers :

\015\012This should make no difference the way the camera performs. I believe that R12 is the buffer for shooting in burst mode. Is it on all the time?
\015\012R12 is not an error message, it is a normal message, in fact telling you that the camera has a 12 photo bufffer that stores the pictures as they are written to the memory card. What is most likely happening is that the camera is not able to write to the SD card. Are you using a genuine, non counterfeit memory card? There are a lot of them about, especially from vendors on the internet selling them for 'too good to be true' prices.

Wont Focus I dropped the camera from my tall dresser about 5 feet and now it wont focus. It makes a clicking noise when I try to zoom in. Also when I zoom in it gets dark around the coners of the screen. Can we fix this or do we need to take it in and get it repaired.

Back focus My D300 looked like it was focusing behind the subject. I set up 8 objects on the lawn, each one 3 feet behind the other. I mounted my camera on a tripod, selected a shallow depth of field, and shot each object. I found that at close range, my camera focused fine. The farther away the object, the more the camera focused behind the object. I returned the camera to Nikon for repair under warrantee. They made some adjustments. The focus has definitely improved, but I don't think it is qu

Does anyone have instructions for getting at the lens mechanism? I totally understand the risks of doing this myself, but the cost of getting a shop to do this is nearly as much as a new camera!

I vacuumed it, then slapped it against the side of my hand whilst turning it on - now it turns on properly with the lens out, but it wont focus - so you can only take blurry photo
