SB-800 flash overexposure with D600?

Thanks for your suggestion

I checked my overexposed pictures, and they're all at ISO400, so Auto ISO didn't boost the ISO in those instances.

Do you think Auto ISO might be causing the problem in some other way? I will try shooting with it disabled.

Is anyone getting overexposed indoor shots with their D600 and SB-800? I'm using TTL in P mode (Auto ISO sets it to ISO 400). It doesn't always do it. I was wondering if I would get more reliable exposures with their newer 9xx series flashes.

Turning off Auto-ISO with flash work is highly advisable. The results have always been erratic and somewhat unpredictable, even in the pro bodies.

Auto-ISO boosts the ambient exposure (boosting ISO, if need be, not just shutter speed) to such a high level in interior settings that the flash invariably over-exposes something. TTL just doesn't address all those variable "ideally" and reduce the ambient exposure. In reality, the camera is doing what you're telling it to; that just produces bad images.
