Adapter H is the camera mount portion of the bellows (see esif under
photomicro). If the other vendors have similar parts it would sure be a neat
way to switch the bellows to another camera. Moose might be right though,
the OM to EOS adapter might be cheaper than either a "C" or "N" version of
the adapter H.

I'm too much of a wimp to figure out manual exposure with bellows extension
.. so it's stopped down, auto, OTF. No reason you couldn't meter wide open
in manual, then make all the adjustments.

If the camera doesn't fire the shutter after the cable release has stopped
down the lens, it would seem very error prone. The camera might start
exposure while the aperture is still moving. Sure seems that any manual
bellows would stop down the lens before tripping the camera. The Olympus
double cable release might not match up perfectly with another vendors
camera but most likely it's still going to stop down the lens before
tripping the shutter.

Dean - I've seen some of your impressive macro work long ago. You should
post a link to some again.
