My wife and I are shooting a wedding today and it seems the D700 took today to act up. 2 problems have surfaced. 1. The camera (occasionally) will not focus and release the shutter. If we shut it off or switch lenses it works again. 2. The flash will fire the modelling flash by itself. Also, the flash will not fire by itself occasionally. Both the lenses and flashes work fine on our D300, so it appears that the D700 is acting up. I have tried the 2 green button reset, but the problems remain. Has anyone seen this happen and can anyone suggest a way to work around this for the wedding? Thanks!
