I have a K20D and a K-5, and I keep wondering about this non-feature:
When I shoot with exposure bracketing, i.e. take a series of shots at different EVs of the same scene, why does the camera move the mirror between each of the pictures instead of taking ONE measurement and then just lock the mirror up, shoot the 3 or 5 images, and only then lower the mirror again? Wouldn't that be much faster? Or are the electronics (sensor) so "slow" that they can't handle the gained speed?
To clarify: I am aware that there are more moving parts involved, e.g. focussing and aperture. But my point is: The camera could offer a special "fast bracketing" mode, in which it assumes a fixed aperture and fixed focus for the entire bracketed sequence, and only varies ISO and/or exposure time. I'm pretty sure the camera mechanics can handle that, since it's already partly possible with the mirror-lock feature (i.e shutter independent from mirror, focus and aperture). Meaning, it's all just a question of software.
(Man, as a software developer, it really bugs me that camera firmwares aren't open sourced, and that the makers are so closed up about their software dev process)
