probably will not be worth the effort, money, and time. if it's a screw mount lense then ebay has lots of screw mount adapters

The issue with an adaptor is that the lens will not be set at the correct length and you will lose your focus to infinity.

If the mirror lens (600mm??) most are 500mm/f8, has a M42 screw mount or a T mount, then you can remove the Oly mount and put on a Pentax Mount.

Don't get a T mount and M42 mount mixed up, they are the same thread size, but different thread pitch.

I seriously doubt there are any Olympus to Pentax adpaters out there. :roll:
