Sirui IronStar Lens
The Sirui IronStar Lens is a full-frame anamorphic cinema series built around a 1.5x constant squeeze and fast T1.9 aperture. The core collection includes 35mm, 45mm, and 60mm focal lengths, with 135mm also now listed in the IronStar family. The lenses offer a 46mm image circle, 270° focus rotation, 16-blade apertures, and interchangeable PL/EF mounts. Blue and Neutral flare versions let filmmakers choose between a pronounced anamorphic character and a more restrained rendering.
For narrative films, commercials, music videos, documentaries, and cinematic content, Sirui IronStar Lens produces oval bokeh, strong horizontal compression, and distinctive anamorphic flares while maintaining detailed imagery. The 35mm and 45mm focus as close as 0.65m, while the 60mm reaches 0.78m. Its matched gear positions, 92mm filter thread, near-zero focus breathing, and consistent optical character make Sirui IronStar Lens a practical choice for building a cohesive professional cinema setup.
