Good info Ray, thanks.ray_parkhurst wrote:I have configured several systems with Tominons. I pick them up when they are in good shape and going cheap, so have a box full of 17's, 35's, 50's, 75's, 105's, and a few 135's. Plus I have a few Rodenstock Eurygon 35's. They're good lenses but have that pesky 40mm Copal thread. Usually it makes sense to make the system ALL MP3/4-based because of this. I even had Raf make me some Vivitar adapters that go from the 48mm dovetail on the Vivitar bellows to M40, to minimize and simplify adapting. It allows the Vivitar bellows to be short enough to frame a Lincoln Cent with the 50mm, which is a fairly nice lens.
Raf is the best, he is very helpful and generous with his time. That is Rafcamera: https://www.rafcamera.com/ FYI.
