This is more of a RANT than a question. Having had a D300 for over 12 mths what not a tiny bit of bother I decided to (upgrade) to the D700. I took my camera with me to my sons graduation. Bad move very bad move d700 24/70 Nikon lens SB600 flash all charged all sorted or so I thought. First few images OK not brilliant slightly over exposed and according to histogram as well checked the usual things -/+ compensation etc then it started to go pear shaped buttons wouldn't respond and I mean all buttons. The display was still on in LCD screen battery was still fully charged. Ok switch off and start again ok for a few shots then same again. The day was sunny no rain so no water involved and my cameras get better looked after than the wife (or so she says) OK switch off lens off and back on and again OK for a few images then same again! but here is the best bit this is my second D700 to do this and this happened to a friend of mine with his own lenses so not a problem with the lens. So the time has come to say good bye. I would like to say this was a happy relationship but can no longer trust the camera.
