SIRUI 20mm T1.8 1.33x S35 AF Anamorphic Lens (Sony E, Blue Flares)

2.35:1 widescreen look in 16:9 • eye-tracking autofocus • blue flares • oval bokeh

Overview

Combining true 2.35:1 widescreen anamorphic imagery with the convenience of subject-tracking autofocus, the SIRUI 20mm T1.8 1.33x S35 AF Anamorphic Lens is a versatile wide-angle tool designed for Sony E-mount Super35/APS-C cameras. With a 1.33x squeeze and an ultrafast T1.8 aperture, it delivers strong low-light performance and impressive subject separation with signature oval bokeh.

A precision STM stepping motor enables smooth, accurate, and quiet autofocus with eye-tracking support—rare for anamorphic lenses. Dedicated controls include an AF/MF switch and an AF-Lock button. A female USB-C port allows firmware updates, while the compact, lightweight build suits handheld, gimbal, and run-and-gun shooting.
