It is a testament to the persistent meme of "Leica M lenses are the best in the world" that everyone wants to adapt them to whatever camera they're using, whether the camera is suitable for them, or they for it, ... or not. Pretty amazing stuff. And more than a bit on the silly side.
A fun test, howsomenever. I suspect the only mating with this adapter that would work other than for pretty tight macro work would be the couple of Leica M lenses that have an available Visoflex 'short focusing mount', like my Hektor 135mm f/4.5. (On this and a couple other lenses, the lens head unscrews from the focusing mount to allow a short helicoid mount or a short bellows mount to be used.) I don't suspect that they would outperform good Pentax lenses, but if you had the right lenses it would be a fun setup to work with. Leica M lenses do superb things when fitted on Leica M bodies. You have a full complement of them, Stan, and should simply buy a Leica M body to use them with. Assuming you want to keep them and use them, of course! :-) G > On Jan 4, 2017, at 11:42 AM, Stanley Halpin <s...@stans-photography.info> > wrote: > > Recently on the Facebook pentaxian group, there was mention of an adapter for > using Leica M lenses on K-mount. > We have all heard that the lens mount to shutter plane distance is just wrong > and beyond fixing with an adapter.
