there is this thread under canon sub-forum here about using AEB when camera is in Manual mode.
after checking online canon dslr manual for 1000D, 400D & 40D, it is stated AEB can be used when camera is in manual mode. according to another forum, the CS2 gets strange results but another person get correct results.
shutter speed was adjusted while aperture and iso remains unchanged, though this is not stated in the user manual for the 3 cameras mentioned. i confirm this with my 40D.
I would like to know if Nikon, Olympus, Pentax, Sony, Fuji can activate AEB while the camera is in Manual mode. if so, which parameter did the camera adjusted?
