Key Features — Sirui 50mm T2.9 1.6x

50mm T2.9 Maximum Aperture: A relatively bright T2.9 stop for an anamorphic prime, giving filmmakers more flexibility in lower-light shooting conditions.
APS-C Format Coverage: Designed specifically for APS-C sensors, making it a natural match for Sony E mount APS-C mirrorless cameras like the FX30 or a6700.
Lightweight 415g Build: At 415g, it is unusually portable for an anamorphic lens, suiting run-and-gun, travel, and gimbal-based productions.

Description — Sirui 50mm T2.9 1.6x
The Sirui Saturn 50mm T2.9 is a manual focus anamorphic prime lens designed for APS-C mirrorless systems, available in Sony E mount. With a maximum aperture of T2.9 and a 50mm focal length sitting squarely in the standard range, it offers a practical and accessible entry into anamorphic image-making. At just 415g, it punches well above its weight class in portability, keeping rigs light without sacrificing the distinctive anamorphic rendering filmmakers value.
The 62mm filter thread provides easy integration with widely available filter systems. There is no autofocus or image stabilization — both noted in the specs — so this lens rewards shooters who embrace a deliberate, cinema-style workflow. Whether you're building a compact anamorphic kit or adding a standard focal length to an existing setup, the Saturn 50mm covers the essentials in a focused, no-frills package purpose-built for APS-C mirrorless shooters.
