Description — Sirui 135mm T2.9 1.8x
The Sirui 135mm T2.9 Anamorphic Lens is a prime telephoto optic with a full-frame image circle, purpose-built for mirrorless camera systems. Available in Sony E, Canon RF, Nikon Z, and L-Mount configurations, it offers broad compatibility across the major mirrorless ecosystems. The lens delivers a T2.9 maximum aperture, providing solid light transmission for telephoto anamorphic work.
As a manual focus only design, it caters to video-focused shooters who prioritize controlled, deliberate focus operation. The 82mm filter thread accommodates standard production filters including ND glass. At 1,295g, the lens has a substantial build consistent with professional anamorphic optics.

Which camera mounts does the Sirui 135mm T2.9 Anamorphic support?+

Does this lens work on full-frame cameras?+
Yes. The lens is specified as full-frame format, meaning it is designed to cover the image circle of full-frame mirrorless sensors without vignetting on compatible full-frame bodies.
Does the Sirui 135mm T2.9 have autofocus?+
No. The lens is manual focus only. This is typical for dedicated anamorphic cinema lenses, where manual focus control is preferred for precise, repeatable focus pulls in video production.
What filter size does this lens use?+
The lens has an 82mm filter thread. This is a common size for professional-grade lenses and allows the use of standard 82mm ND filters, which are frequently used in video production to control exposure.
How heavy is this lens, and do I need additional support?+
