OK, I'm having a complete brain fart here... I haven't used my D700 for ages (as I've been concentrating on my M4/3s cams). My problem is that (with Nikon AF lenses), I always have the camera set in A mode and then use the rear command dial to adjust aperture (with the lenses locked at f22). Well now, this just doesn't seem to work. I can't for the life of me get either command dial to do anything with the aperture. I tried doing a reset and it still doesn't work. I've also tried this with different AF lenses... same issue. Camera has the latest firmware.
I know I'm probably overlooking something simple, but for the life of me I can't seem to suss out what it is.
Any clues would be really appreciated.
