Product description
The Sirui 20mm T1.8 is a 1.33x anamorphic lens with autofocus for Micro 4/3 cameras and the Super 35 / APS-C format. It turns 16:9 footage into a 2.35:1 widescreen image, and its STM motor handles eye focus and subject tracking. The blue flare suits sci-fi, mystery and music video scenes. The 20mm and 40mm share gear positions and the 77mm filter thread.
Anamorphic look with autofocus
The 20mm T1.8 combines the cinematic look of a 1.33x squeeze with the convenience of autofocus – for handheld, gimbal and car rig shooting.
1.33x anamorphicT1.8–T22STM autofocusSuper 35 / APS-C77mm filterMicro 4/3
Blue flare
The blue version draws distinct blue flares that suit sci-fi, mystery and music video scenes.
2.35:1 from 16:9
Once de-squeezed in post, the 1.33x squeeze turns 16:9 footage into a 2.35:1 widescreen frame.
Eye focus
The STM motor focuses fast and accurately and keeps eyes or a tracked subject sharp while recording.
Aluminium body
A light yet rugged aluminium alloy housing built for demanding shoots.
Gimbal friendly
The compact lens (about 480–495 g) sits close to the body and keeps the centre of gravity tight on a gimbal.
T1.8 fast aperture
Plenty of light even at dusk, a very shallow depth of field and strong bokeh that separates the subject from the background.
Distinctive anamorphic bokeh
The 40mm renders hexagonal bokeh wide open. Stopped down to T2.4, both focal lengths shift into the 1.33x elliptical bokeh with the classic anamorphic look.
Two focal lengths, one layout
The 20mm and 40mm share gear positions, the 77mm filter thread and consistent colour. Swap lenses without readjusting accessories, even on a gimbal.
Clicked or declicked aperture
The Click ON/OFF switch selects a clicked aperture for photos or smooth travel for video. The AF/MF button switches focus mode in one move.
360° focus throw
The extra-long focus throw gives fine manual control for precise, accurate focusing every time.
Contacts and firmware
Electronic contacts pass EXIF data to the file, and firmware is updated via the USB-C port.
