Cinematic Anamorphic Lens for Super35

The Sirui 20mm T1.8 1.33x anamorphic lens delivers a distinctive widescreen squeeze on APS-C sensors. It features 16 elements in 12 groups for exceptional clarity and minimal distortion. An 11-blade diaphragm produces smooth, circular bokeh with neutral flare characteristics. Autofocus via STM motor adds precise eye-tracking for video and photography.

Suited for Solo Shooters Needing AF Anamorphic

Filmmakers who want anamorphic aesthetics without manual-focus limitations will benefit from the fast, quiet stepping motor. The 0.4m minimum focus distance allows close-ups with shallow depth of field. Buyers requiring full-frame coverage or a different squeeze ratio should look at other optics.

1.33x Squeeze on Super35/APS-C Sensors

This specification determines the horizontal field of view, equivalent to a 22mm full-frame lens. It creates the cinematic aspect ratio directly on the sensor without cropping. Confirm your camera uses an APS-C or Super35 format to match the designed image circle.

Questions about this item

What is the closest focus distance and maximum aperture this 20mm T1.8 anamorphic lens can reach?

The lens focuses as close as 0.4 m and opens to a fast T1.8 aperture, giving shallow depth of field and strong low-light performance at its widest setting.

How much heat or fan noise does the built-in STM stepping motor produce during extended autofocus use?

The STM stepping motor runs quietly and generates minimal heat, so it stays unobtrusive during long video takes or continuous eye-tracking sessions.

Which camera bodies and sensor formats are natively compatible with this E-mount 1.33x squeeze lens?

It mounts directly on Sony E-mount bodies and covers Super35/APS-C sensors, delivering the full 1.33x horizontal squeeze without vignetting.
