Description — Sirui 50mm T2.9 1.6x
The Sirui 50mm T2.9 Anamorphic is a manual-focus prime lens built specifically for APS-C mirrorless camera systems. Its 50mm focal length places it firmly in the standard range, making it a natural fit for interview work, narrative scenes, and documentary-style shooting where a natural perspective is desired with the added character of anamorphic optics. The lens opens to a maximum of T2.9, providing reliable light transmission in a variety of shooting conditions.
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.
Mount options span Sony E, Canon RF, Nikon Z, L-Mount, and Micro Four Thirds, giving this lens one of the broadest compatibility profiles in its category. Manual focus operation aligns it with professional cine workflows where measured, deliberate focus control is the standard working method.
