The Distinctive Visuals of this Anamorphic Optic

What truly defines the SIRUI 35mm T2.9 1.6x is its impressive 1.6x squeeze factor. This isn’t just a number; it’s the key to unlocking genuinely cinematic visuals. When paired with a 3:2 sensor mode, this anamorphic optic delivers a stunning 2.4:1 aspect ratio, a classic widescreen format that instantly transports viewers into a theatrical experience. Push it further to a 16:9 sensor mode, and you achieve an even wider 2.8:1 frame, reminiscent of ultra-widescreen blockbusters. This substantial squeeze factor means a significantly wider angle of view horizontally than a spherical lens of the same focal length, effectively giving you the horizontal field of view of a 22mm lens while maintaining the vertical perspective of a 35mm. The resulting images are immediately recognizable for their characteristic charm, rich with the signature anamorphic traits that filmmakers covet.

Pronounced 1.6x Squeeze Factor: This high squeeze ratio is paramount to the lens’s cinematic character, providing a more dramatic stretching of the image and the distinctive anamorphic look compared to lower squeeze ratios.
Achieving Cinematic Aspect Ratios: Effortlessly produces classic 2.4:1 widescreen footage with a 3:2 sensor and an even more expansive 2.8:1 when shooting in 16:9, delivering truly immersive visuals.
Iconic Sci-Fi Lens Flares: One of the most sought-after features of an anamorphic lens, this optic generates beautiful, streaky blue horizontal lens flares that add a dynamic, ethereal, and often "sci-fi" quality to scenes, especially when pointed towards light sources.
Creamy Oval Bokeh: The unique optical design renders out-of-focus elements in a distinct oval shape, creating a smooth, dreamy background blur that gently separates subjects from their surroundings, enhancing depth and artistic expression.
Wider Field of View Perspective: Thanks to the 1.6x squeeze, the 35mm focal length offers a horizontal field of view equivalent to roughly a 22mm spherical lens on a full-frame sensor, providing expansive shots perfect for landscapes, establishing scenes, and immersive environments.

Precision Engineering: Crafting the Anamorphic Experience

The physical construction of the SIRUI 35mm T2.9 1.6x anamorphic prime is as impressive as its optical performance. Housed in a robust aluminum alloy chassis, this lens feels substantial and durable in hand, ready to withstand the rigors of professional film sets or adventurous independent shoots. Despite its sturdy build, it maintains a relatively lightweight profile at just 2.06 lbs (934g), making it a manageable option for handheld work, gimbals, or drone setups. The design ethos prioritizes usability and seamless integration into existing cinema workflows. Both the aperture and focus rings are geared, providing tactile feedback and precise control, which is essential for accurate rack focusing and smooth aperture adjustments. This geared design also ensures compatibility with follow focus systems, a crucial feature for professional production environments.

Durable Aluminum Alloy Construction: The lens body is meticulously crafted from robust aluminum alloy, providing exceptional durability and a premium feel that ensures longevity and reliability on set.
Smooth, Geared Control Rings: Both the aperture (T-stop) and focus rings feature precise gearing, enabling fluid and accurate manual adjustments and seamless integration with follow focus units for professional control.
Standardized 82mm Filter Thread: A common 82mm front filter thread allows for easy attachment of various filters—ND, polarizers, or diffusion—offering creative flexibility and protection for the front element.
Complex Optical Design (18E/13G): Comprising 18 elements in 13 groups, the sophisticated optical structure is engineered to minimize aberrations, control distortion, and deliver sharp, high-contrast images characteristic of high-end cine lenses.
10-Blade Aperture for Smooth Falloff: The 10-blade aperture diaphragm creates beautifully circular out-of-focus highlights and ensures a smooth, pleasing transition from in-focus to out-of-focus areas, enhancing the overall aesthetic of the bokeh.

Mastering Manual Control and Optical Performance of this Cine Lens

Operating the SIRUI 35mm T2.9 1.6x is a distinctly tactile experience, offering filmmakers complete manual control over focus and aperture. This manual-only approach encourages a more deliberate and artistic filmmaking process, allowing for precise control over depth of field and focus pulls that autofocus systems simply cannot replicate with the same nuanced touch. The maximum aperture of T2.9 is impressively bright for an anamorphic cine lens, allowing for excellent low-light performance and the ability to achieve shallow depth of field even in challenging conditions. The 10-blade aperture ensures that when stopped down, light sources render with beautiful, smooth bokeh, enhancing the cinematic quality further. With a comfortable rotation angle of 120° for the focus ring, precise focus adjustments are easily achieved, while the relatively close minimum shooting distance of 3ft (0.9m) allows for intimate, detailed shots.

Dedicated Manual Focus System: The purely manual focus design empowers cinematographers with absolute control over critical focus, enabling precise rack pulls and creative manipulation of depth of field essential for cinematic storytelling.
Bright T2.9 Maximum Aperture: A wide T2.9 aperture allows for superior low-light performance, enabling shooting in dimly lit environments and facilitating the creation of extremely shallow depth of field effects, isolating subjects beautifully.
Flexible T16 Minimum Aperture: The ability to stop down to T16 provides ample control over exposure and depth of field, offering versatility for bright outdoor scenes or when a deeper plane of focus is desired.
Close Focusing Capability (0.9m): With a minimum shooting distance of just 3 feet, this lens allows for detailed close-up shots, adding another layer of visual storytelling to your projects.
Balanced Weight and Ergonomics: At 2.06 lbs and 4.7 inches long, the lens strikes a fine balance between being robust and portable, making it comfortable for extended shoots and well-suited for various camera setups without being overly cumbersome.
