Yo,

very recently, I acquired a very nice OM-F, which I wanted to have because
(besides from just loving to use OMs) I think its electronic focusing aid is
quite an interesting step in camera-technological evolution.
>From a book I have (Olympus Fotoschule, in German, by Richard Hünecke; real
good) I learned that there is something called an IN FOCUS cord that is used
to connect the camera to a winder which it triggers when the subject comes
into focus.
I figure that it goes into the jack to the right of the lens mount on the
camera. I have never seen one of these cords for sale anywhere. Are there
any sources that might be able to supply one?
An alternative might be to make my own cord, which I suppose - having been
an electronics technician - can't be very hard to do. Some technical
information would make this easier (hint: John Hermanson, if you could
provide any info it would be highly appreciated), though, especially: What
kind of plug does the jack take? It looks like the 2.5 mm version of the
typical earphone plug used in many small radios etc. (which use the 3.5 mm
version, though) might fit; I don't want to try, though, for as long as I
don't know what's inside there is no way to know whether I might cause
damage trying a wrong plug.  And what exactly does it do? Does it just short
two contacts, acting like a switch (which would allow me to connect it to
the remote jack I put into my el cheapo no-name winder) or does it put out
some kind of an electrical impulse?


MtFbwy,
Volkhart
