Originally posted by davemdsn The longer duration of sounds and of mirror black out are most likely the result of the SR mechanism. Who among us would give up SR in the K10D? I happen to like it. For all the complaining about lag and mirror black out, the camera still seems to capture the exact moment I intend for it to capture and it still pulls off 3 fps, which is plenty fast for me. Seems to me that all of this perceived lack of responsiveness hasn't effected the actual performance of the camera.
The total shutter lag in (most) dSLRs is short enough that many people just don't notice it. They learn to anticipate the critical moment a tenth of a second (or a few tenths, depending on the camera).
One also has to anticipate a bit to allow for human reaction time. (The time between when you think "Now!" and when your finger actually moves. This can be as long as the total shutter time in a fast camera.
That said, Canon seems to have put some effort in reducing the mirror movement time in their 1D MkIII. That sucker smokes....
