Telephoto anamorphic for Canon RF

The Sirui 135mm T2.9 1.8x anamorphic lens mounts natively to Canon RF cameras. Its 1.8x squeeze factor produces a widescreen aspect ratio and signature horizontal flares straight from the sensor. A T2.9 aperture gathers ample light for low‑light scenes. Manual focus rotates through 120 degrees for repeatable pulls.

Extends the 1.6x full‑frame anamorphic set

This 135mm focal length joins the existing 1.6x series with matched colour science, flare behaviour and gear positions. The longer reach yields a shallower depth of field for smoother background separation. Equivalent horizontal field of view matches a 75mm spherical lens, useful for portrait, landscape and product work.

Consistent rendering under sustained use

High optical sharpness and minimal distortion hold across the frame during extended takes. The constant T2.9 transmission maintains exposure when lighting shifts. Matched gear placement allows quick lens swaps without re‑rigging follow‑focus gear, keeping the workflow steady on long shooting days.

Questions about this item

What Canon RF-mount clearance does the 135mm T2.9 1.8x anamorphic lens need to fit?

The lens mounts directly to the Canon RF bayonet with no adapter required; its telephoto length clears the mirrorless flange distance.

How do I focus the manual 135mm anamorphic correctly, and what step is often missed?

Turn the focus ring through its 120-degree rotation for smooth pulls; the missed step is setting the diopter first so marks match the sensor plane.

When will the 1.8x squeeze factor need re-calibration or service?

The fixed 1.8x optical squeeze is permanent; only routine cleaning of the front element and gear-pitch checks are needed over time.
