an Amedeo adapter runs $300 or so. You would be better to get the LM version. If you ever run into an LTM lens with bad glass, the optics module unscrews from the S-Mount and would go into the LTM focus mount.
So I have offers for a 10.5 LTM in outstanding condition on RFF for $425 and an 8.5cm f/2 LTM MIOJ on GetDPI for $375, also in outstanding condition. The 10.5 comes with the M adapter, though that doesn't really matter. If I can only afford one and bokeh fanatic that I am, which would you recommend?
