Sirui 75mm f/1.8 1.33x Anamorphic Lens (Sony E)

Sirui 75mm f/1.8 1.33x Anamorphic Lens (Sony E-Mount)
The Sirui 75mm f/1.8 1.33x Anamorphic Lens is a precision-engineered, mid-telephoto cinema prime designed natively for Sony E-mount cameras with APS-C sensor sizes. Capable of capturing a 1.33x anamorphic squeeze, this lens expands your horizontal field of view by 33%, letting you capture breathtaking, cinematic widescreen imagery without the need for digital cropping. When paired with a standard 16:9 sensor capture mode and de-squeezed in post-production, it outputs a stunning, cinematic 2.4:1 aspect ratio. Delivering hallmark anamorphic characteristics like sci-fi blue streak flares and organic oval bokeh, this 75mm prime is a powerful creative tool for filmmakers seeking to inject a big-budget, cinematic look into independent productions, music videos, and commercial narratives.

Cinematic 1.33x Widescreen Squeeze & Blue Streak Flares
33% Horizontal Field Expansion: Optically widens the horizontal framing axis without altering the vertical compression. This replicates the spatial character of a wider lens while preserving the pleasing compression, background separation, and subject rendering of a traditional 75mm telephoto prime.

Cinematic 2.4:1 De-Squeezed Aspect Ratio: Transforms standard 16:9 widescreen captures into an ultra-wide 2.4:1 cinema canvas upon post-production de-squeeze, eliminating the resolution loss associated with traditional top-and-bottom digital black bars.

Horizontal Blue Streaks: The advanced optical element array is engineered to transform single points of bright light into classic, horizontal sci-fi blue streak flares, while aggressively suppressing distracting stray light reflections.

Soft, Oval Bokeh Geometry: Features a specialized optical architecture that warps out-of-focus background highlights into beautifully elongated, vertical ovals—delivering the signature dreamlike aesthetic prized by professional cinematographers.

Fast f/1.4 Optics & Fine-Grained Controls
Bright f/1.8 Maximum Aperture: A fast f/1.8 aperture excels in ambient low-light scenarios, reducing image noise on set while producing an incredibly shallow depth of field that ensures crisp subject isolation against a completely melted background.

13-Blade Diaphragm Array: Built with a dense 13-blade iris design that maintains a circular aperture geometry throughout the stop range, guaranteeing a smooth, natural, and organic out-of-focus rendering profile.

Sophisticated 16-Element Layout: Comprises 16 high-grade glass optical elements arranged in 12 independent groups, treated with multi-layered protective coatings to enhance light transmission, maximize contrast, and preserve razor-sharp core focus.

Robust Mechanical Build & Field Layout
Heavy-Duty Tactical Housing: Constructed from durable, precision-machined materials to withstand the rigorous demands of active on-set production schedules and camera rig configurations.

Dual Imperial & Metric Scales: The tactile, smooth-turning manual focus ring features clearly engraved distance measurement reference markings displayed in both feet and meters for easy tracking by camera assistants and focus pullers.

Universal 67mm Filter Interface: Built with standard front 67mm filter threads, making it easy and affordable to screw on circular polarizing, variable ND, or special-effect diffusion filters directly to the lens barrel.
