The short answer is to NOT use the OM-1. The OM-1 has that little issue
with the aperture stop-down mechanism that shakes the camera (even with
mirror lockup) like it's coming off of a high.
An OM-2, 3 or 4 series body (even the OM-2000) will be much smoother in this
circumstance.
Long answer is to use a LONGER shutter speed. As a general rule, you should
avoid 1/4 to 1/30 second with all OM bodies, but especially the OM-1. When
you use a longer shutter speed than 1/4 second, the percentage of the
exposure that is affected by vibration is greatly reduced. With a 2-second
exposure, for example, you will have no shutter-vibration blurring.
