Olympus OM lenses suck on digital cameras. Better leave them alone for the film users.

Digi's have software to correct distortions and misshapen images because they are inferior to film and need that stuff to make a reasonable image. When you substitute 'legacy' lenses for the electronic ones, all the correction is lost and you get worse junk than the junk you normally get from a digi.

So, stay away from film lenses on digi's and kid yourself into thinking that computer generated junk is a real picture.
