The SIRUI 35mm T2.9 is a full-frame anamorphic cinema lens with a Canon RF mount. It has a 1.6x squeeze factor and a horizontal field of view equivalent to a full-frame 22mm lens. The same lens is also made in E, L and Z mounts.
The 1.6x squeeze gives a 2.4:1 aspect ratio in a 3:2 sensor mode and a wider 2.8:1 frame in a 16:9 mode. It produces anamorphic effects such as sci-fi style lens flare and oval bokeh. The look matches other SIRUI full-frame anamorphic lenses.
The housing is made of aluminum alloy and the lens is lightweight. The aperture and focus rings are geared, and an 82mm filter thread allows filters to be attached. Focus is manual.
