Lens Overview — Sirui 50mm T2.9 1.6x

The Sirui 50mm T2.9 Anamorphic Lens for Leica L-Mount is a prime anamorphic lens designed for full-frame mirrorless cameras using the L-Mount system. With a maximum aperture of T2.9, this lens offers a solid light-gathering capability suited to both controlled and lower-light shooting environments. As a manual focus lens with no autofocus or image stabilization, it is oriented toward deliberate, hands-on shooting workflows — typical of cinematically minded photographers and videographers who prioritize optical character over automation.

The lens is classified as a standard focal length prime at 50mm, and its anamorphic type designation means it delivers the distinctive visual rendering associated with anamorphic optics. The full-frame lens format ensures compatibility with L-Mount cameras featuring full-frame sensors, making it a versatile option within that system. Weighing 560g with an 82mm filter thread, the lens has a substantial but manageable physical build.

The 82mm filter thread allows for use of compatible circular filters. Overall, this is a purpose-built anamorphic prime for L-Mount shooters seeking a manual, cinematic look from a 50mm perspective on full-frame bodies.
