Yesterday during the middle of a wedding my D3s stopped focusing correctly. The camera was indicating that there was correct focus, on single mode; beep, solid green dot in the view finder, but looking at the LCD screen the images were all soft.
I have yet to check every possible combination of camera to lenses, but I did check my lenses on my D700 and that did not yield any issues.
I was wondering if anyone has any knowledge or experience w/ such an issue. This camera has been reliable for 2 years now.... never had any problems.
