About this product

The Sirui 20mm T1.8 1.33X S35 AF Anamorphic Lens (E mount, Neutral Flare) is a compact, lightweight anamorphic lens designed for cinematic video and photography. It features fast, smooth autofocus with eye-tracking for precise focus during dynamic shots. The 20mm focal length provides an expansive field of view equivalent to a 22mm full-frame lens, ideal for landscapes, starry skies, and tight indoor spaces. With a minimum focus distance of 0.4 meters and a T1.8 aperture, it delivers strong depth and shallow depth of field. The lens produces a 2.35:1 widescreen cinematic aspect ratio without cropping, using a constant 1.33x squeeze factor. It supports both autofocus and manual focus modes, offers a choice between neutral or blue flare effects, and has 11 aperture blades for soft, lemon-shaped bokeh. Compatible with S35 sensors and most full-frame cameras, though slight vignetting may occur on full-frame formats.
