There were some experiments about 20 years ago to
establish a wireless TTL flash system involving
OM T-series flash. Even a (british) patent was
involved, but it did not succeed commercially,
since the marketer choose to retain to tripods ...
Well, that is past. The only system I know of
that does wireless TTL flash control for/with OM
cameras is made by METZ, see
<http://www.metz.de/en/photo_electronics/SCA-3083_digital.227.html>
for reference of the newest developement. But
all older models of that line (SCA-3080 and
SCA-3082 and all their subline incarnations
-- marked by M1, M2 an so forth) work as fine.
Their must be a SCA-321 controlled METZ master
flash wired to your camera. All further flashes
then are wireless, set to slave mode, controlled
by those SCA-308x foots.
Not all METZ flash models are suitable, see Metz
for fitting ones (or ask me again ...).

PS: There is a different-idea fun model for the
digital world from METZ, mecablitz 28 CS-2 digital
<http://www.metz.de/en/photo_electronics/digital/mecablitz_28_CS-2_digital.2
25.html>
that "learns" what is best for you and your camera.
