I'm not absolutely convinced. Although I take a lot of handheld shots
for various reasons (laziness, the person/critter/light/expression will
be gone, etc.) I suspect there is a difference, at least sometimes.
Remember it still takes the curtain 1/60 sec. to traverse the film, so
camera movement can still displace part of the image realtive to other
parts. Remember those old pictures of race cars where the car seemed to
lean forward? Those were taken with (mostly?) 4x5 cameras, like Speed
Graphics, with vertical focal plane shutters. Although the slit was
narrow enough to give a fairly high effective shutter speed, it took so
long for the curtains to traverse the film that the subject moved
significantly during the exposure, distorting the image. It's
interesting that the direction of shutter motion happened to make the
cars look like they were leaning forward to go faster, rather than
leaning back.
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. Vertical shutter
cameras like the OM2000 would have different effects.
Perhaps John "11x16" Lind or a lurking Gary "Stop that Vibration" Reese
know more?
This is nothing but speculation about things we'll never see on web pics
or 4x prints.

comment too far, I was only answering the camera shake issue, because
that was the only question asked.
At those shutter speeds, and those focal lengths, if the photog keeps to
good
form, there shouldn't be ANY advantage to using a tripod.
