Re: ISO 640 example at DR400 in a non X Series camera

I think that your further investigation will confirm that DR200 will work in hardware (at least in P or A modes) at ISO200 and ISO400, as well; I am pretty sure that DR200 works in hardware at ISO Auto400 and I know that the hardware DR400 works when ISO is set to Auto400 (where the camera adjusts the ISO automatically, and is not locked into ISO400), because I have exposed thousands of shots where it did so..

Good work, good observing.

It now appears that you could be absolutely correct.

And please take that smirk off your face... 

Right now I am not sure what happens at ISO640 becauuse I don't think I shot anything at that point.  But I do have ISO100, 200, 400 and 800 shots from an F770 to examine.
