I'm selling this because it isn't compatible with my new camera and I found it more of a novelty lens (a very sharp novelty though).
The lens is in great shape with light external wear and perfect optics. The viewfinder is in excellent condition as well. The mount is LTM/L39 and is NOT rangefinder coupled. It includes the original front lens cap, but the rear cap is an aftermarket 3d-printed one that works just fine. I'm also including a 3d-printed cold-shoe mount that will let you mount the finder next to an external meter (A Reveni fits next to it) and a front cover for the finder. The cover is notched to allow it to be used when the finder is mounted next to the meter.
Terrific tiny sharp rectilinear lens. Great w/ a tiny IIIc. I connected 46<>72mm step rings, put some black gaffer tape in the interior for a snug fit - ala, a 72mm filter adapter for my orange filter shooting b&w.
I had 3d-printed such an adapter for mine, but after seeing how big it was and how much it would block my viewfinder, I gave it up.
It's really a neat lens for someone who's into ultra-wide photography, but I found I prefer shooting with 28mm-50mm lenses. And with it being incompatible with my latest purchase, it became time to let it go.
I've been using the bejeebus out of mine and it is a great lens. Specialty, sure, as it's so wide I can accidentally take pictures of my fingers, but surprisingly good field of view.
Someone should definitely give this a try, it makes really nice images for not a lot of money.
