Our IRON GLASS Cine TMIR-10A 28mm F3.5 PL is an old Sovjet Lens rehoused by IRON GLASS. It features a metallic 0.8 gear for focus and aperture. Our set of lenses is tuned with an additional "cat-eye" shaped mask to create a more anamorphic bokeh. Very well suitable for full frame format. See here what IRON GLASS writes about this lens: MIR-10A 28mm F3.5 is a bit of a dark horse. It’s a less known Soviet lens, but very unique and worthy nevertheless. Its closest focusing distance very impressive at just 0.20m. This lens has minimal distortion, 3-dimensional feel and good sharpness even wide open, so it’s definitely worth considering.
