Interesting about movement related artifacts. Perhaps that explains the
A1's mechanical and electronic shutters. Mechanical at slower speeds
with the shutter curtain closed and blocking any change during readout
to prevent motion artifacts. Electronic at much higher speeds where
motion is not a problem. And, of course, flash exposure is very short
and can have the high sync speed of the electronic shutter.
