Description — Rokinon 21mm T1.5
The Rokinon 21mm T1.5 Cine Lens is a prime, wide-angle lens built for mirrorless camera systems and tailored to the demands of professional cine production. The T1.5 maximum aperture makes it a capable performer in challenging lighting conditions, giving cinematographers flexibility without relying solely on artificial light. Weighing just 306.2g, it strikes a balance between durability and portability that works well for handheld and shoulder-rig configurations.
Focus is entirely manual, consistent with the expectations of dedicated cine glass and compatible with follow-focus systems for smooth, repeatable pulls. The 58mm filter thread accommodates standard filtration options, from ND to polarizers. Image stabilization is not included, so stabilization strategy will need to be addressed through rigging or in-body solutions. As a 21mm fixed focal length lens in the wide-angle range, it delivers a consistent field of view with no variable aperture shifts during shooting — a practical advantage for exposure-conscious cinematographers.
