Key Features — Sirui 50mm T2.9 1.6x
1.6x Anamorphic Squeeze: Captures a squeezed anamorphic image that, when desqueezed in post, produces a wider cinematic aspect ratio with characteristic oval bokeh and horizontal lens flares.
T2.9 Maximum Aperture: A wide-enough opening for shallow depth of field and usable performance in lower light conditions, suited to controlled cinematic shooting.
50mm APS-C Prime: Standard focal length on APS-C sensors, delivering a natural perspective equivalent to roughly 75mm on full frame after accounting for crop factor.
Manual Focus Design: Smooth manual focus ring built for deliberate, repeatable focus pulls typical of anamorphic cinematography workflows.
Sony E Mount: Directly compatible with Sony APS-C mirrorless bodies such as the ZV-E10, A6700, and FX30 without adapters.
82mm Filter Thread: Large filter thread accommodates ND and polarizer filters commonly used in cinematic shooting to control exposure and reflections.

Description — Sirui 50mm T2.9 1.6x
The Sirui 50mm T2.9 Anamorphic Lens is a manual focus prime built for APS-C mirrorless systems on the Sony E mount. With a maximum aperture of T2.9, it delivers a wide enough opening for cinematic shooting in varied lighting conditions while maintaining the character associated with anamorphic optics. The fixed 50mm focal length places it in the standard range, making it a versatile choice for narrative, documentary, and short-form video work.
Weighing 1050g, the lens has a solid, substantial build suited to rigged camera setups. The 82mm filter thread is a practical feature for anamorphic cinematographers who regularly use large ND filters or polarizers. There is no image stabilization built into the lens, so pairing with a body that offers in-body stabilization is worth considering.
Focus is entirely manual, which aligns with the deliberate shooting style that anamorphic lenses typically demand. This lens is purpose-built for APS-C sensor cameras and is available in the Sony E mount configuration.
