Lens Overview — Sirui 50mm T2.9 1.6x

The Sirui 50mm T2.9 Anamorphic is a manual-focus prime lens designed for APS-C mirrorless cameras, offering filmmakers and photographers an accessible entry point into anamorphic image-making. Built around a 50mm focal length and a maximum aperture of T2.9, this lens brings a distinctly cinematic character to productions without requiring a full-frame system. It is available in an impressive range of mounts — Sony E, Canon RF, Nikon Z, L-Mount, and Micro Four Thirds — making it a versatile option that can follow a shooter across different camera bodies and ecosystems.

Classified as a standard prime within the anamorphic category, it covers the APS-C format and is built for mirrorless camera systems. Focusing is entirely manual, which suits the deliberate, controlled pace of video production and gives operators precise control over their focus pulls. The lens accepts 67mm front filters, which is useful for those looking to add diffusion, ND, or other glass in front.

Weighing 560g, it strikes a reasonable balance between a substantial, professional feel and portability for handheld or gimbal-based shooting. Image stabilization is not included, so stabilization must come from the camera body or rig. Overall, the Sirui 50mm T2.9 Anamorphic is a well-specified lens for APS-C mirrorless shooters seeking the anamorphic look.

With a 67mm filter thread, adding front-of-lens accessories is straightforward. At 560g, the lens is substantial enough to feel professional without overloading compact rigs. It carries no image stabilization, so camera-side or rig-based stabilization is recommended.
