55mm · f/1.2
The Revuenon 55mm f/1.2 Auto (Tomioka) is a rare, fast fifty with solid metal build and smooth focusing, though engravings may wear. Optically, it has low contrast wide open but sharpens by f/2, with a sweet spot at f/5.6; bokeh is creamy and distinctive. It suits photographers who enjoy characterful rendering and post-processing flexibility, especially for black-and-white work.
