Carl Zeiss Otus 55mm f1.4 APO-Distagon Lens- ZF. I'd say this lens is comparable with the Leica Noctilux and Canon 200mm f2 for image quality and bokeh. I've used it mainly on a Canon 1DX via an adapter ring.
Adapter for canon full frame available at extra cost. This item is in the category "Cameras & Photography\Lenses & Filters\Lenses".
