Roger's point about using a cable release reminded me of something: I
don't use a cable release with my OM4 because it doesn't work. It must be
my cable release, but when I was taking photos of a Shuttle launch years
ago, it just stopped releasing the shutter. It was then that I faintly
remembered something about using only the right cable release with the OM4.
Has anyone else heard of anything like this?

The caution I'm aware of is avoiding undue pressure on the cable release
plunger. Adjust plunger travel to only what is needed for tripping the
shutter if it's adjustable. I believe this is similar to the John H.
warning quite a while back about using screw-on "soft release" buttons on
the shutter release. [Using one on an OM-4 is completely unnecessary
anyway.] Don't screw a cable release into the shutter release button too
tightly. Just barely finger tight works fine. The memory/memory-clear
switch under the shutter release, and its centering spring returns, can be
damaged if you thread it in too tightly and start turning the shutter
release button (when screwing it in or trying to unscrew it).
My cable release is a generic one, about a foot long and works fine on an
OM-1n, OM-2S and OM-4. Also have a pneumatic one with a hose that unreels
over 20 feet and a bulb at the other end. For night architectural shots
and city-scapes when the "decisive moment" is measured in at least minutes,
if not in hours, consider using the self-timer. It's easier.
