Sirui's compact anamorphic wide-angle — 1.33x squeeze at 24mm f/2.8 for APS-C cinematic content.
The Sirui 24mm f/2.8 1.33x Anamorphic was released in 2020 as an APS-C anamorphic prime for Sony E-mount, producing a 1.33× horizontal squeeze for approximately 2.4:1 aspect ratio output when de-squeezed from a 16:9 sensor. Thirteen elements in 10 groups (Schott optical glass). Eight aperture blades. 72mm filter thread. At 780g. 0.60m MFD.
The optical design uses 13 elements in 10 groups (Schott optical glass, nano coating). Eight aperture blades. The 72mm filter thread (M72×0.75 — some retailers incorrectly list 77mm). At 780g the lens is substantial for an APS-C prime. Minimum focus distance of 0.60m. 1.33× anamorphic squeeze — de-squeezed output produces approximately 2.39:1 (2.4:1) on a 16:9 APS-C sensor. f/2.8 maximum aperture. APS-C image circle. Sony E-mount.
The 1.33× squeeze provides cinematic scope (2.4:1) output from standard APS-C sensor bodies without the extreme MFD constraints of higher-squeeze anamorphics: 2× squeeze lenses often require diopters for normal close-focus work, while 1.33× maintains practical working distances. The characteristic oval bokeh and horizontal lens flares are present but less extreme than 2× squeeze designs.
On the used market the Sirui 24mm f/2.8 1.33x Anamorphic E is available at APS-C anamorphic prime pricing. Condition checks: anamorphic oval bokeh (verify with test shot), 72mm front element for marks. APS-C only. 1.33× squeeze — requires de-squeeze in camera or post. Compatible with Sony E-mount APS-C bodies.
