SIRUI, a veteran Chinese camera accessories manufacturer, released its 50mm f/1.8 1.33x lens

Veteran Chinese camera accessories manufacturer SIRUI released its 50mm f/1.8 1.33x lens on Indiegogo. SIRUI anamorphic lens produces image circle covering APS-C sensors and comes in versions with Sony E-mount, FUJIFILM X-mount, and Micro 4/3 mount. Weighing in at only 560g, this compact, sturdy, and durable lens is perfect for on-the-go filmmaking.

SIRUI anamorphic lens is a must-have for filmmakers who want to create works with the widescreen aspect ratio and Hollywood-style lens flare. Compared to the traditional 50mm APS-C lens, it boosts the horizontal field of view by 33% to achieve a FOV equivalent to an APS-C 37.5mm lens. In a 16:9 setting, users can easily produce a cinematic 2.4:1 widescreen video.

Built with a precision optical structure and multiple layers of nano-coating, SIRUI anamorphic camera lens will deliver a vivid, recognizable horizontal blue flare. Another characteristic of the SIRUI anamorphic lens is the out-of-focus elements. The lens has a large F1.8 aperture ring. Each lens has 10 aperture blades that create specular out-of-focus highlights and more pleasing bokeh.

“Shooting anamorphic is notorious for being prohibitively expensive for indie filmmakers. We’ve made the lens smaller and lighter, and its affordable price allows everyone in the mass market to have a chance to produce film-level works, a meaningful way to promote photographic creations,” says Sonny Liu, marketing director, SIRUI.
