Sirui 50mm f/1.8 1.33x Anamorphic Lens
The Sirui 50mm f/1.8 1.33x Anamorphic Lens is designed to bring the cinematic anamorphic look to independent filmmakers, YouTubers, and professionals who want to elevate their storytelling. Compact, affordable, and packed with signature anamorphic characteristics, this lens is a favorite among creators looking to achieve Hollywood-style widescreen visuals without the massive cost of traditional anamorphic glass.
Cinematic 2.4:1 Aspect Ratio
At the heart of the Sirui 50mm f/1.8 is its 1.33x anamorphic squeeze factor, which allows footage shot in a standard 16:9 format to be de-squeezed into a cinematic 2.4:1 aspect ratio. Unlike cropping, this method retains the full sensor resolution, ensuring sharper details and more immersive visuals.
This gives filmmakers the ability to tell stories in the same widescreen format used by major motion pictures, making every frame feel more dramatic and professional.
Distinctive Anamorphic Aesthetics
The Sirui 50mm anamorphic lens delivers the unique cinematic visuals that are highly sought after in filmmaking:
-
Oval bokeh: Unlike spherical lenses, the Sirui 50mm produces oval-shaped background blur that enhances depth and adds emotional weight to close-up and portrait shots.
-
Horizontal blue lens flares: When exposed to light sources, this lens generates striking blue streak flares, reminiscent of classic Hollywood anamorphic cinema.
-
Immersive widescreen composition: By expanding the horizontal field of view, the lens allows filmmakers to capture more of the environment without stepping back, perfect for narrative storytelling.
Fast f/1.8 Aperture for Low-Light Shooting
Equipped with a fast f/1.8 aperture, the Sirui 50mm excels in low-light conditions, giving filmmakers the flexibility to shoot at dusk, indoors, or in moody environments without relying heavily on artificial lighting.
The shallow depth of field also makes it possible to isolate subjects with cinematic oval bokeh, creating visually engaging storytelling that draws attention exactly where you want it.
Compact, Lightweight, and Filmmaker-Friendly
One of the key advantages of the Sirui 50mm f/1.8 is its lightweight cine build, making it practical for use on handheld rigs, stabilizers, tripods, and gimbals. Its metal housing ensures durability, while the manual focus and aperture rings are designed for precise, smooth control during shooting.
Despite being an anamorphic lens, it remains compact and travel-friendly, making it a go-to option for independent filmmakers, traveling creators, and production houses.
