This 50mm f/1.8 Super35 Anamorphic 1.33x Lens from Sirui adds 1.33x anamorphic squeeze to your images to achieve standard 2.4:1 widescreen aspect ratios. Designed for Super35/APS-C cameras with a Leica L mount, the lens features an aperture range of f/1.8 to f/16. A lens construction of 11 elements in 8 groups creates the characteristic, stretched oval bokeh of anamorphic lenses for a unique cinematic look.
The focus ring is capable of rotating 143.6° for intuitive control. A 67mm filter thread allows you to add compatible filters and customize your exposure. Markings on the lens are in both feet and meters. When used with a full-frame sensor, the 50mm lens is equivalent to a 53mm lens horizontally.
