Flash and auto iso on the Nikon D7000
The way auto iso and flash interact on the D7000 seems to have changed since the D80. And the new algorithm seems to make a complete pig's breakfast of the job.
Here are 3 photographs, all taken at f5.6, 30th sec.
The first is without auto iso and flash. Iso is 100.
The second is auto iso and no flash. Iso is 2200.
The third is auto iso and flash. Iso is again 2200. You can see the shadows from the overhead domestic lighting and it seems the camera is trying to use a mixture of lighting, squelches the flash and puts up the iso instead. But the white balance for the mixed lighting does not appear to work. And the iso is ridiculously high.
I've taken another photograph where the camera has decided to use f8 and iso 6400, 6400 being the maximum iso I've allowed. That seemed to have been a very daft choice for a combination of settings.
The algorithm seems all wrong to me.

Totally agree!
At least they could have given us a freedom of choice - whether to fall back on flash and keep ISO at its lowest (D90 and other oldies' behavior) or to bump up ISO to let as much ambient light as possible (the new approach with d3100, d7000, etc).
I wrote to Nikon support. Waiting for reply.. Hope they'll address it thru a firmware update.

Great pigture, its good that we now have a choice between flash and the ISO. This has revolutionised the People's world.
