The Sirui 35mm ƒ/1.8 1.33x Anamorphic Cinema Lens with L-Mount is a standard anamorphic prime that covers Micro Four Thirds sensors. A standard focal length sees close to natural human perspective, which suits dialogue and coverage where the framing should not draw attention to itself. Its 1.33x squeeze produces a 2.36:1 field of view on a 16:9 sensor, the gentlest of the common squeeze factors and the easiest to pair with a standard 16:9 body. Anamorphic character is present but restrained. A fast ƒ/1.8 aperture lets camera operators separate subjects from their backgrounds or get the most out of available lighting when filming in darker environments, and the lens closes to ƒ/16. It uses an L-Mount with manual focus. The focus barrel is marked in feet.
Key Features
Standard Micro Four Thirds Coverage
The lens covers Micro Four Thirds sensors. A standard field of view sits near natural perspective, the neutral option for dialogue and everyday coverage where framing should not announce itself.
1.33x Anamorphic Squeeze
A 1.33x squeeze reaches 2.36:1 from a 16:9 sensor, the gentlest of the common anamorphic factors and the easiest to pair with a standard 16:9 body. Flares and oval bokeh are present but restrained, which suits work that wants anamorphic character without it taking over the frame.
ƒ/1.8 Maximum Aperture
At ƒ/1.8 the lens separates subjects cleanly from their backgrounds and gets the most out of available lighting when filming in darker environments. It closes to ƒ/16.
191.2° Focus Throw
Its 191.2° focus throw is short, racking quickly from close focus to infinity — fast to operate and forgiving for a solo operator, at the cost of finer separation between distance marks.
Imperial Focus Scale
Distance marks are engraved in feet. Matching scale units across a lens set matters on a crew that calls distances aloud, and mixing feet with meters mid-set invites errors.
