Description
The SIRUI 20mm T1.8 1.33X S35 Anamorphic Lens is built for filmmakers who want true anamorphic character without giving up autofocus. It suits solo shooters and small crews working with gimbals or fast-moving documentary subjects who need reliable focus tracking. A constant 1.33x squeeze delivers the widescreen anamorphic look straight out of camera.
- STM Autofocus with Eye-Tracking: An STM stepping motor drives fast, smooth autofocus with eye-tracking for stable focus lock on moving subjects.
- 1.33x Squeeze, 2.35:1 Widescreen: A constant 1.33x anamorphic squeeze produces a 2.35:1 cinematic aspect ratio in 16:9 mode.
- T1.8 Aperture, 11 Blades: A fast T1.8 aperture with 11 aperture blades supports low-light work and soft, lemon-shaped bokeh.
- 0.4m Minimum Focus Distance: Focuses as close as 0.4m (1.31ft), unusually near for an anamorphic lens.
- 16 Elements in 12 Groups: Built from 16 elements in 12 groups, including five cylindrical elements and one aspherical element.
- Compact and Lightweight: Weighs about 480-500g depending on mount and runs roughly 90mm long, suited to handheld and gimbal use.
- Native E/X/Z/L/MFT Mounts: Available in Sony E, Fujifilm X, Nikon Z, L-Mount, and Micro Four Thirds native mounts, sharing a 77mm filter thread.
