I miss Steve Grimes. He was always incredibly helpful. If I could send work his way, I did. These days, though, it often isn't as practical to mount old process lenses in shutters. Sure, if you have some decent shutters sitting around, the price isn't too bad, but new shutters have gotten very expensive. One can buy a Sinar behind the lens shutter for the cost of one new Copal 3 shutter. The Sinar shutter will allow you to use as many barrel lenses as you like, assuming you really need a shutter in the first place. With 8x10 at least one can often do without. In any case, while you can get some very high focal length process lenses, I doubt that many of them are telephoto.
