This is the Mitakon 20mm f/0.95 lens for Fuji X Mount. It's open box/like new, with the original leather box, outer paper case thing for the box, and the lens hood (and all papers inside). It essentially gives a look of a full frame 30mm f/1.425 lens which can be very ethereal and alluring. I believe this is the same optics as the Zhongyi 20mm T1 cine lens but in a photographer focused lens design. It's manual focus and feels like it's made entirely of metal and glass. I don't have many specs and measurements for it but the filter size is 72mm for if you want to use any ND or diffusion type of filters.
In my opinion this is optically far superior to the Mitakon 35mm f/0.95, though they both have a very unique look that's otherwise hard to get on APSC. This lens unlike the 35mm, doesn't have field curvature so while it's got an extremely shallow depth of field when wide open, when you need sharpness (say in a landscape photo), you can actually get a fully sharp and in focus image.
I can ship this out whenever, by USPS.
