I did a studio shoot today with the D3, 24-70, 70-200vr and shot off about 300 photos. 2 major issues with the D3 that I have NEVER experienced with the rock solid D2X:  About 1 out of every 10 photos, I had what seemed to be focus lock issues. I would hit the shutter button 1/2 way and it focuses... but when I depress it all the way, it would take a good 2-5 seconds before the shutter would go off. Sometimes, not at all... I would turn off and on the camera while the model just held the pose for over 30 seconds. I believe I missed a lot of good shots because of this crazy issue.  JPG/Expeed issues..... I got 2 jpg files out of the 300 shots that I took that could not be read by the computer. It just gives me a read error and that's it. In addition to that.... I get a jpg that looks like this! When pulled up on the D3, in the gray area is a part of another picture! Scrolled around a bit and then go back to that photo and the gray area is just colored lines! Then later couldn't even find the shot. I shot raw+fine so, so after the shoot, I was able to recover from the nef... but this is really bad. What gives? Has anyone experienced these issues before?
