Originally posted by Jodokast96 You do have full control. It's called bracket the shots yourself - manually. If you want to Auto-Bracket, use an auto mode. If you use the Auto-Bracket in manual, how is the camera supposed to know you want to maintain DOF instead of shutter speed? It only makes sense that both settings might change.
It almost never makes sense to bracket exposures with aperture. Bracketing is usually used with a still camera and a (relatively) still subject - So shutter speed will have little effect on the photo but a change in aperture WILL.
Manual bracketing is not an option as it is SLOW. See my previous qualifier about a "relatively" still subject.
Sadly, the K10D's bracketing function is pretty abysmal. The shutter button needs to be held down the entire time, and it brackets both aperture and shutter. The K20D is much better in this regard - You can bracket with one touch of the button, combine self timer mode with bracketing (although it triggers the timer between every exposure - good mirror-lockup wise, bad in terms of speed, it would be far better to keep the mirror up for all exposures.), and the K20D does not bracket aperture, only shutter.
