I got this Leica screw-mount lens very cheap early this year as it was broken - the helical was completely frozen. I repaired it, but I have no Leica or Canon rangefinder ! So I took off the lens head and mounted it on bellows -
Komura made an extensive range of rangefinder lenses for Leica/Canon screw mount and Visoflex. This Komura was the longest focal length lens ever made with a rangefinder linkage, so it is a bit of a unique item. Very impractical though ! Other Komura 200mm's were either for Visoflex (no linkage) and/or SLR, and are very different in design.
The lens is a very extreme telephoto - its very short for its focal length. It also, curiously, has two aperture scales, on both sides of the lens - I don't know why.
Right now its on another interesting item, a Kopil folding mini-bellows. This thing not only folds up, but its got just the one rail and a short one at that, so it fits in a pocket.
The lens is a bit of a dud - it is unusable wide-open, its soft and has a strange set of aberrations. It could be that its defective, maybe some element isn't in right, who knows. It does get sharp by f/8. It has a typical Komura golden color rendering, which I find attractive.
