I thought it was only 1 oil spont in my D600 sensor, man, it's a lot of them! Locked

i really don't know what you mean by that. this is so similar to the anti-pixel-peeper comments i keep seeing.  i.e.: if you don't look, you won't see what's wrong!  i now have 9000 clicks on my d600.  just wet cleaned it on the 20th and ran 400 more shots yesterday.  there's plenty of new spots.  they seem to be in a pattern from lower right towards middle left so i doubt if it's dust.  more likely oil.  only 1 shows at f4 so i'll let it go another week, then do a wet clean very carefully again.

i 100% agree that Nikon dropped the ball on this.  their rep is suffering. personally, i would have a hard time recommending anyone buy this camera.  just imagine if a friend got it and then they had these issues for months!
