Be sure ... According to the instruction manual and my experience with the DS, using the DS/2 and DL/2 a K-mount or M-series lens will only stop down to taking aperture at the time of exposure in Manual or B exposure mode. The iris mechanism is operated the lens is actually wide open at exposure time ... the actuation of the iris is after the exposure as the mirror returns.
All other exposure modes default to Av regardless of the position of the mode selector. The camera sets an exposure time for whatever the ISO, lighting conditions, and lens full-aperture might be. If it is otherwise on the DL, this is news to me. :-) Godfrey On Jun 25, 2006, at 12:53 PM, Jens Bladt wrote: > It seems that I am able to photograph just fine in M, Av and Tv with a > K-lens on the DL! > This is relly true?
