So if I shoot w/md the camera will atomicity shoot at 500 sec?
How?

B26) What shutter speed do I get with an OM-2(N) fired with a winder or
motor drive when the shutter speed ring is set to B?
1/500th sec.

The problem relates to how Olympus designed the MD's and Winders. On many
systems, the film does not advance to the next frame until you let up on
the MD/Winder button. The OM system does not work that way. The film
advances to the next frame as soon as the shutter closes, whether it's in
Single or Sequence mode. IMO this is an advantage, but it is at the cost
(trade-off) of not being able to use the "B" shutter speed setting. See
the "Main Characteristics" text in the eSIF for the MD 1, MD 2, Winder 1,
and Winder 2:

Also looked in my Winder 2 manual under its specs. It lists the usable
shutter speeds for the OM-1[n], OM-2[n] and OM-10. In manual exposure
mode, all were 1-1/1000th . . . NO "B." What the manual doesn't state is
what happens if you do use the "B" setting.
The "B" on all the single-digit bodies is mechanical. The MD/Winder lets
up on the shutter release mechanism inside the camera as soon as it has
been actuated so it can get on with winding to the next frame as soon as
the shutter closes . . . whether or not you're still depressing the button
on the MD/Winder handle. Clint or John H. will have more details. My best
educated guess is this all happens in about 1/500th second!
