Anybody tried out the M39 L39 Converted 28mm f/2.8 INDUSTAR 69

[Sonnar Brian]

I converted one in Jan 2008, ground down an internal ridge on the mount by ~1mm. Then reset the focus ring to allow scale focus.
I sold it cheap to someone with an M8, maybe ~$50 or so.

Not suitable for a full-frame camera, unless you want vignetting as a special effect. Test on a Canon P.
