It seems to me that vertical motion of a horizontal shutter camera could
cause similar effect on a 35mm SLR. It would be less obvious, because of
the higher relative curtain speed, but might cause otherwise unexplained
'unsharpness', especially if it were a highish (technical term) frequency
vibration from mirror slap, vertical diaphram mechanism 'slap', etc.
Physical movement from hand held motion might take the form of barely
discernable distortion in horizontal lines.
Hi DM,
Don't know if you've read the following article or not. While it doesn't
address the questions you've raised it does offer an overview of some other
interesting factors to consider.
