I've had this old standard with a Konica adapt-all mount for ages. You can get an adapt-all fitting designed especially for 4/3, and I probably will, but for now the lens feels very secure with a Konica-to-4/3 adapter mounted behind the original Konica mount, and the combination is actually fairly easy to handle. I haven't priced these lenses lately, but I used to see them regularly on ebay. The lens could use a cleaning, but it's sharp and handy, with pleasing bokeh. Although the depth of field is shallow, I'm happy now I never got round to selling it. In case you don't remember it, the adapt-all system is just what the name implies. I've got a Nikon adapter, too, for a film 35mm SLR, so I think I could attach the rig to one of the current Nikon DSLRs as well as to my G1. I'll post a picture of the G1 Tamron combo in the Show Us Your Adapted Lens thread above.
