The Sirui Vision Prime 1 35mm T1.4 is a full-frame prime cine lens with manual focus. It has a native Sony E mount, and the mount can be changed by the user to Canon RF, Nikon Z or L-Mount. The 46mm image circle covers full-frame mirrorless sensors, including in Open Gate mode.
The optical design uses three aspherical elements, one ED glass element and four HRI glass elements. A multi-layer nano coating reduces reflections, flare and ghosting. The lens is designed to show almost no focus breathing and to keep distortion tightly controlled. Its 12 aperture blades and T1.4 maximum aperture produce round bokeh and allow shooting in low light with natural light.
The body is aluminum alloy and weighs 590 g. The stepless focus ring has a 270-degree throw and works with follow focus systems. The lens balances on gimbals and suits handheld shooting. It shares its size, weight, gear position, 67mm filter thread and 72mm outer front diameter with the other lenses in the series.
