#17. "RE: My D700 won't take a picture" In response to In response to 16 Thu 15-Aug-13 03:43 PM by tma
For whatever it's worth, I recently started encountering the same issue with my D700 and a Quantum T5D-r setup using the TTL adapter. Never happened before with the same setup, and I've used this setup a LOT for the last few years, without any issues.
What you described has happened intermittently during the last two evening sessions while working an event.
