Sirui IronStar IRON-35-B 35mm
The full-frame 35mm T1.9 anamorphic lens delivers a 1.5x squeeze, fast light gathering, and blue flares with a 16-blade aperture for oval bokeh. Its interchangeable ARRI PL/Canon EF mount, 0.8 MOD gears with 270° focus rotation, and 92mm filter thread suit matte box cinema rigs despite a 998g weight. This lens is best for cinematographers and commercial video shooters who prioritize deliberate anamorphic character over travel portability.
