Wide Anamorphic lens for rent, a compact, autofocus anamorphic cine lens d
The SIRUI Cine AF 20mm T1.8 1.33x Anamorphic lens is not a true full-frame anamorphic lens — it is designed for Super 35 / APS-C sensors and has an approximate 37 mm image circle, which almost approaches full-frame coverage but will vignette on a full-frame sensor.
Sensor Coverage
Designed Format: Super 35 / APS-C (37 mm image circle)
Full-Frame Use: Technically the image circle almost touches full-frame dimensions, but vignetting will occur if used on full-frame sensors without crop or software correction.
What This Means for Shooters
-
On Super 35/APS-C cameras (e.g., FX30) the lens covers the sensor fully and produces proper anamorphic imagery.
-
On full-frame cameras (FX6/FX9) the edges will vignette or fall off before reaching true full-frame coverage, because the lens’s image circle doesn’t reach the required 43 mm diameter.
-
Sony FX3 with Active Stabilization ON, the SIRUI Cine AF 20mm T1.8 1.33x is covered. Sony FX3 Active SteadyShot applies an additional sensor crop (approx. 1.1× on top of full-frame).
Sensor Coverage: Super 35 / APS-C. On Sony FX3, the lens covers the image area when Active Stabilization is enabled.
It brings the distinctive anamorphic aesthetic — oval bokeh, gentle compression, and wide framing — into a form factor suitable for handheld, gimbal, and solo work.
The SIRUI Cine AF 20mm T1.8 1.33x Anamorphic lens combines a wide field of view with cinematic anamorphic character, making it a versatile choice for filmmakers who need widescreen visuals without heavy rigging or manual focus complexity. Its autofocus system, driven by an STM stepping motor, offers fast, smooth, and precise subject tracking — even in handheld and run-and-gun scenarios.
Unlike traditional anamorphic lenses that require dedicated focus pullers, this SIRUI lens supports autofocus with eye tracking on compatible Sony cameras, helping keep moving subjects sharp during dynamic shoots.
