A mint C-Biogon 21mm with box, paper work, original front and rear caps, generic 46mm front cap (because the OEM Zeiss caps are horrible).
**$925**
This lens is mint all around. No signs of use, even though I used it pretty constantly for over a year. Always had a protective filter on (not just for the front element but also to act as a hood of sorts). No Zeiss "wobble" or grit, and everything rotates smoothly.
Optically the C-Biogon is about as good as it gets for a 21mm on film; no visible distortion, extremely sharp, very compact. It can be used on a 1.5 crop sensor without color cast (I've tried on my NEX 5N), but there is extreme red edges and corners with a full frame sensor (ie M9). The color cast can be resolved with corner fix though. But ultimately I'd say this lens is probably most suited for film, crop sensor, or exclusive M9 (or MM) B&W users.
I'd love to keep this lens for my film cameras, but with the purchase of a new Leica SEM 21 I just can't afford to keep two modern 21mm lenses.
I'm only offering shipping within the 50 United States, Canada and Puerto Rico.
Free fully insured FedEx ground to PayPal verified addresses in the 50 United States, and $30 fully insured shipping to PayPal verified addresses in Canada and PR.
I've sold quite a lot at RFF and ebay under the same username.
