Sirui SATURN Anamorphic 50mm T2.9 Overview
The Canon RF-mount Saturn 50mm T2.9 1.6x Carbon Fiber Anamorphic Lens from Sirui provides a classic anamorphic look in a compact, lightweight form. Ideal for gimbal, stabilizer, drone, and handheld use, this lens measures only 4.2" in length and features a carbon fiber barrel that reduces the weight of the lens. The lens produces horizontal neutral streaks when pointed at a light source, giving your footage a classic anamorphic look.
An image captured in 16:9 is de-squeezed to an anamorphic 2.8:1 aspect ratio, whereas shooting in 3:2 yields a 2.4:1 final image. The T2.9 aperture produces a shallow depth of field, separating your subject from the foreground, and the 10-blade aperture creates oval bokeh effects.

- The large 45mm image circle covers up to full-frame camera sensors.
- Aspherical elements eliminate chromatic aberration.
Lightweight Design
- This Saturn-series lens is made with a carbon fiber front barrel that reduces the overall weight while remaining durable.
- The compact, lightweight design is ideal for handheld, gimbal, and stabilizer use.
Anamorphic Design

Constant 1.6x Squeeze
