If I shoot at auto ISO and pop up the built-in flash on the D800, with flash set to -1.5EV, I get a nice fill flash, with the ISO settings in the menus used. In fact, there's no difference with or without the flash popped open, except for a bit of fill. Everything else looks and works the same just like one would expect.
If I attach an SB-700 suddenly it gets very strange. The max ISO setting in the camera is ignored in A mode. Instead, it seems the max is whatever I had manually set before switching to auto ISO. If that was 400 while the menu says 3200, the 3200 is used until I turn on the SB-700. At that point it switches to 400! And as if that weren't enough, it refuses to drop the ISO until it gets to sync speed (1/250). Is this normal? It's driving me nuts. Is there a way to make it operate like the built-in flash? I need fill at low light (like streetlights) at night with a Zeiss 18mm lens. I want 1/20 f/4 ISO 400, not 1/250 f/4 ISO 3200! The SB-700 can zoom out to 14 with the diffuser while the built-in will result in a huge lens shadow. Am I stuck shooting with everything set manually - M mode, ISO, flash power? The problem is the lighting changes too fast and wildly to just keep changing it manually to match. (And this is why I have a camera with fancy electronics, anyway.)
I have the camera set to slow sync, flash to TTL BL. Nothing I do seems to be able to get this fancy-pants flash system to work right.
