When my D300 meters and shows me an iso of 3200 w/o flash (dark room lit by TV only and distance of 18ft.), and then I pop up the flash, the indicated iso drops to an iso of 200. When I shoot, the actual/final iso may end up being 350 or 450 or so, depending upon distance. It never holds to an iso of 1600 or 3200 or anywhere near that level.

If your camera does this, first check setting e3. Is your camera set to TTL or Commander? I am not sure on which camera Nikon made the change, but on a D300S, if using auto ISO and then pop up the flash, ISO does not drop to the set ISO. My D70S would always drop to set when flash was turned on unless the flash did not have the needed power.

Yes, my e3 setting is indeed correctly set on TTL when conducting my test and it operates as expected and not at all like the OP problem.

Thanks for the replies, thats exactly my problem, in low light room (no flash), iso reads 3200 (auto iso is on), then pop up flash, iso doesnt drop (when set to TTL), when using Commander mode and auto iso is on, the 3200 does drop to the set iso (200 iso in my case). I just thought that in TTL mode when using flash the (when flash is up) camera would be 'clever' enough to realise that 'hey I don't need 3200 iso cos he's gonna use flash' and drop the iso, guess not, so Commander mode it'ss have to stay then, unless I again missed something...

Jostian, Which camera and firmware are you using? My D300 firmware is A 1.10 B 1.10 and it does just what you want yours to do when using auto iso and pop-up flash. That is, drops the iso to what I have set and then adjusts upward on the fly when the flash goes off.

Regards, Jim
