I've always shifted before setting exposure and no exposure problems with
the OM-2S or OM-4 provided I remember to stop it down. I've had occasional
trouble with the OM-1n because of how the meter in it behaves. The
aperture pin to bias the meter is fixed and doesn't move with the aperture
ring to bias the meter. Metering must be done stopped down. Unlike the
OM-2S and OM-4 which respond immediately to the stop-down, the OM-1n meter
takes a while to respond. My procedure is:
stop open >> compose image (including shift) >> focus >> stop down >> set
exposure >> make photo.
I know this is a little contrary to the eSIF text about the lens, but it
has worked for me. Occasionally I've stopped open to double check focus or
between frames and forgotten to stop down again. Yes, you can use it with
the camera in auto mode.
Glad to see you're using it for more than just architectural shots. Don't
keep us in suspense! What was the solution to the shift creep.

Please excuse my ignorance, but I want to make sure I have things straight.
The order of operations when using a shift to take photos of buildings and
such is pretty simple: align film along same plane as subject >>> set the
proper exposure >>> shift lens >>> take photo.
What about when using the lens for creative perspective control? I like to
change the plane of the film and shift the lens around to create interesting
viewpoints. What is the correct technique to determine the exposure when
the lens has already been shifted to acheive the desired perspective? Here
is what I have been doing:
compose image by shifting lens and film plane >>> 'un'-shift lens >>> set
the proper exposure >>> 're'-shift the lens >>> take photo.
I thought I was doing this the correct way until I got some hideous results
the other day. Unfortunately, I didn't take any notes and cannot figure
what happened.
Also, I have always used my shift in Manual mode. Can they be used in Auto
mode as long as I pre-set the aperture and stop it down manually?
Thanks!

Lastly, many thanks to Sunil Manga for helping me out with my creeping
shift!
