Features:

True T1.5 High-Speed Aperture for Consistent Cinematic Exposure

The Sigma 35mm T1.5 FF High-Speed Prime Lens uses a true T-stop measurement, not a photo-style f-stop, meaning the light transmission you set is the light transmission you get. This is critical for professional cinema work where exposure consistency across multiple lenses and scenes matters. The fast T1.5 aperture allows filmmakers to shoot confidently in low-light environments while maintaining controlled highlights and shadow detail. It also enables shallow depth of field without relying on extreme lighting setups, giving productions more flexibility, faster setups, and a cleaner workflow on set.

Full-Frame Coverage Built for 6K and 8K Cinema Cameras

Designed with a 43.3mm image circle, this lens fully covers full-frame sensors and exceeds Super 35 requirements, making it compatible with today’s high-resolution cinema cameras and future upgrades. The optical design is optimized for 6K–8K capture, ensuring fine detail, contrast, and clarity across the entire frame. This level of coverage reduces vignetting and edge softness, allowing cinematographers to reframe, crop, or stabilize footage in post without sacrificing image integrity.

Precision Optical Design for Sharpness Without a Clinical Look

With 13 elements in 11 groups, including advanced low-dispersion and aspherical elements, the Sigma 35mm T1.5 FF balances sharpness with natural rendering. Images remain crisp without appearing overly digital or harsh, preserving skin tones and textures while maintaining excellent micro-contrast. This makes the lens ideal for narrative filmmaking, commercials, and documentaries where realism and emotional tone matter as much as resolution.

Smooth, Cinematic Bokeh with a 9-Blade Rounded Diaphragm

The lens features a 9-blade rounded aperture designed to produce smooth, pleasing bokeh and natural highlight transitions. Out-of-focus areas fall off gradually, helping subjects stand out while keeping backgrounds visually pleasing rather than distracting. This contributes directly to a more cinematic aesthetic, especially in close-ups and dialogue-driven scenes where emotional connection is key.

Long Focus Throw for Accurate, Repeatable Focus Pulls

A 180-degree focus rotation gives focus pullers the precision they need for demanding shots. This extended throw allows for subtle adjustments and repeatable marks, making it easier to maintain sharp focus during movement, rack focuses, or complex blocking. The mechanical damping is tuned specifically for cinema use, providing smooth resistance without backlash or inconsistency.

Clickless Iris with Linear Response for Seamless Exposure Changes

The 60-degree clickless iris rotation ensures smooth, silent aperture adjustments during recording. Because the iris response is linear, exposure changes remain predictable and consistent—critical for live adjustments during takes. This allows cinematographers to adapt to lighting changes without visible stepping or audible clicks that could compromise a shot.

Industry-Standard Cine Gears for Professional Rig Compatibility

Both the focus and iris rings use 0.8 MOD gears, the industry standard for professional cinema rigs. This guarantees compatibility with follow focus systems, wireless motors, and lens control units. Gear positions are standardized across Sigma’s FF High-Speed Prime lineup, allowing fast lens swaps without repositioning motors, saving time on set and reducing production friction.

Consistent Color Science Across the Sigma FF High-Speed Prime Line

Sigma designs its cinema lenses with consistent color reproduction across the entire FF High-Speed Prime series. This ensures seamless intercutting between focal lengths without time-consuming color matching in post. For productions using multiple Sigma primes, this consistency translates into faster grading, reduced correction costs, and a more unified visual style.

Rugged All-Metal Construction for Demanding Production Environments

The lens features a full metal housing engineered for long-term professional use. Its dust- and splash-resistant construction allows it to perform reliably in challenging environments such as outdoor shoots, travel productions, and extended shooting days. Laser-engraved markings resist wear, ensuring legibility even after heavy use.

Standardized 95mm Front Diameter for Efficient Lens Changes

A 95mm front diameter allows compatibility with common matte boxes and filters, reducing the need for adapter rings or rig changes. This standardization speeds up lens swaps and keeps production moving, especially in fast-paced commercial or narrative shoots.

Close Focus Capability for Creative Flexibility

With a minimum focus distance of 0.3 meters, the Sigma 35mm T1.5 FF allows for intimate close-ups and detail shots without compromising optical performance. This expands creative options, enabling tighter framing and more expressive storytelling without switching lenses.

Professional Mount Options with Metadata Support

Available in PL mount with Cooke /i Technology, Canon EF, and Sony E-mount, the lens integrates seamlessly into professional workflows. The PL version provides lens metadata such as focus distance and aperture for VFX, virtual production, and advanced post-production pipelines, improving accuracy and efficiency in modern cinema workflows.

High-End Cinema Performance at a Competitive Price Point

One of the strongest unique selling points of the Sigma 35mm T1.5 FF High-Speed Prime Lens is its ability to deliver true cinema-grade optics and mechanics at a price significantly lower than many legacy cinema lenses. This makes it an attractive option for owner-operators, production companies, and rental houses looking for maximum return on investment without sacrificing professional standards.
