Pentax 200mm SMC Takumar M42 wth EOS adapter TEST -13/10/2018 (Processed stack)
I was wanting a fast shorter focal length DSLR lens at modest cost. I decided to try a vintage Pentax lens with M42 mount. These have 45.46 mm flange distance, > 44mm Canon EOS so with a short adapter can be adapted and reach infinity focus for Astrophotography.
