I realized I'm more of a 35mm guy, so I'm letting this one go. I do plan to get another 50, but it'll probably some less artistic than this very unique lens. I've only had for about 10 months, and I purchased it brand new. Everything is that comes in the box is included. Only defect I can see is dents in the lens cap (noted in one of the pictures). It doesn't affect the picture, unless you leave the cap on while taking a picture(rangefinder joke).
I prefer not to ship, but I can be convinced.
