Lens Overview — Sirui 135mm T2.9 1.8x

The Sirui 135mm T2.9 Anamorphic Lens is a prime telephoto optic built for full-frame mirrorless systems, available in Sony E, Canon RF, Nikon Z, and L-Mount configurations. Designed for cinematographers and hybrid shooters who want an anamorphic look on modern mirrorless cameras, this lens sits in the telephoto focal length range at a fixed 135mm. It features a maximum aperture of T2.9, providing solid light-gathering capability for a lens of this type and focal length.

The lens is manual focus only, which is a deliberate choice for the target audience of video-first shooters who prefer precise, repeatable focus pulls. It is classified as a full-frame anamorphic prime, making it compatible with cameras that use the listed mounts without crop concerns on full-frame bodies. The lens accepts 82mm filters, useful for attaching ND filters in video production workflows.

Weighing in at 1,295g, it is a substantial optic that reflects the optical complexity expected of a dedicated anamorphic design. Image stabilization is not present, so shooters will rely on in-body stabilization or rigging solutions. Overall, it targets filmmakers seeking the distinct anamorphic aesthetic in a mirrorless-native mount.
