Our IRON GLASS Cine Helios 44-2 58mm F 2.0 is an old Sowjet Lens rehoused by IRON GLASS. It features a metallic 0.8 gear for focus and aperture. Very well suitable for full frame. See here what IRON GLASS writes about this lens: JUPITER-9 85mm F2 is yet another very popular Soviet lens and it completes the very popular Soviet Trio (37mm 58mm 85mmm). This 85mm is based on Zeiss Sonnar equivalent and shares most of the characteristics with the other 2 lenses it’s often used with. One of its best features is the 15 blade aperture, which keeps that bokeh nice and round at any F-stop. Even though at 0.8m its minimum focusing distance is not outstanding, it’s great for really tight “bohehlicios” shots.
