Exposure Bracketing and ISO

I usually keep AUTO ISO 100-800 settings on my k-x. Yesterday, I was trying HDR and noticed that in some sequences, ISO have changed between the shots (from 100 to 320). This slightly defeated the purpose as I was trying to shoot HDR and increased ISO on one of the shot effectively reduced the dynamic range. Although I could go to menu and fix the ISO to one fixed value, I was thinking that an option to keep the ISO fixed between the bracketing sequence could have been helpful.

As far as I know, there is no such function. You have to manually set your iso to a set value and then bracket your shots, all at the same iso.

Thats pretty much the purpose of AUTO ISO. The camera is doing what it was told to do.
Set ISO to a specific value, then perform the same steps.

I never use AUTO ISO, but you may also need to be in Av, Tv, or M mode to keep ISO from falling back to Auto. (honestly not sure how that part works)
