Avenon 21mm f/2.8 LTM Lans (for Leica Screw Mount Cameras). In excellent, clean condition; I don't see any issues. Comes with original front and rear caps, B+W UV protective filter.
This is a very desirable fast wide angle lens or Leica Screw Mount Cameras (including the the Canon LTM's). Focuses down to 1m (3.5ft).
I originally bought it and used it for a specific project in mind and no longer need it (although I might regret selling it).
There is a bit of information available on this lens - Camera Quest, Classic Camera sites to name a few.
$350.00 including USPS Priority Mail shipping in the Continental USA. Please PM your PayPal account and I will generate a PayPal Invoice.
I've been searching for this lens for a long time because it meters fairly well with the Leica M5, CL, M6 , etc.
I've never tried it with digital M cameras, but I think it will meter correctly.
There is a later version, the last iteration of this lens (aka: Kobalux), which focuses down to .7 meter.
