Nice looking lens... Any particular reason you're set on that lens? (i.e. Do you already own one?) Given the focal length and aperture, there are other similar lenses out there with 55mm or 58mm focal length and fast f/1.4 apertures. Ones that do have available adapters. For example, I have a Minolta 58mm MC lens that is just dandy and set me back just a few dollars... Happy hunting!
