Lens Overview — Rokinon 21mm T1.5

The Rokinon 21mm T1.5 Cine Lens is a wide-angle prime built specifically for cine applications on mirrorless camera systems. With a maximum aperture of T1.5, this lens is well-suited for low-light shooting scenarios where exposure latitude matters. The 21mm focal length sits comfortably in wide-angle territory, making it a practical choice for environmental storytelling, run-and-gun documentary work, or any production requiring a wider perspective.

At 306.2g, the lens is lightweight enough to keep handheld rigs manageable over long shooting days without sacrificing the tactile control that cine shooters expect. The lens is manual focus only, which is standard for dedicated cine glass and allows for repeatable, precise focus pulls when used with a follow focus system. A 58mm filter thread provides compatibility with standard filtration.

Image stabilization is not present, so shooters will need to account for camera movement through rigging or stabilization equipment. The lens is classified as a prime within the wide-angle focal length range, giving cinematographers a fixed, consistent field of view with no zoom creep or variable aperture concerns. This is a purpose-built cine tool designed for mirrorless camera bodies, combining a compact form factor with a fast T-stop rating.

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.
