Revolutionary lenses for the era of high resolution digital cinematography

Performance born of SIGMA's experience in ultra-high megapixel digital photography— now ready to take on every challenge in the world of cinematography.

In the new era of high-resolution movie production, the arrival of reasonably priced, high-performance digital cinema cameras has changed the standard of what makes an excellent product in the industry and has expanded the freedom and potential of movie production. At the same time, when it comes to cine lenses, price and brand recognition are still often taken as proof of performance, which ends up being proportional to the production budget. In contrast to consumer products, professional cinema equipment is by its nature difficult to manufacture in volume, in turn causing lens R&D and innovations in manufacturing technology to lag behind progress in cameras. But SIGMA is different. Responding to the demanding requirements for lenses in the era of ultra-high megapixel still photography, SIGMA has developed the technologies required to produce high-performance lenses in volume. They have what it takes to offer a new solution to the cine lens market.

Image Quality

Inspecting each and every lens

There are three requirements for outstanding lenses: fine design, precise manufacturing and inspection that ensures compliance with all specifications. SIGMA lenses are born of outstanding design concepts and excellent manufacturing technology, but they are not complete until they undergo their uncompromising lens performance evaluation. SIGMA has developed their own A1 proprietary Modulation Transfer Function (MTF) measuring system using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of their quality control inspections. Each and every lens is checked before shipping. Thanks to the ultra-high resolution sensors, high- performance shooting is assured.

Minimization of flare and ghosting

Computer-based ray tracing has been used from the design stage onward to minimize flare and ghosting and enhance contrast in backlit conditions. Ghosting has also been checked at every prototype stage, with its causes identified, assessed, and eliminated.

Sharpness combined with outstanding bokeh effect

To fulfill the high demands for image quality in still photography, SIGMA has solved a wide range of issues. The benefit of these efforts can now be enjoyed in cine lenses as well.

Color balance standardized across the lineup

All of the lenses in the lineup are designed to comply with SIGMA’s CCI standard. Standardized color balance makes color correction a snap.

6K-8K class resolution

The lineup features the same optical system that delivers 50-megapixel or higher resolution in still photography. These lenses are therefore ready for higher-resolution shooting and are ideal for chroma keying as well.

Build Quality

Lightweight and compact

Leveraging the high-precision, high-efficiency mass production technologies developed for its still camera lenses, SIGMA has made extremely lightweight and compact cine lenses a reality. Featuring all functions essential to cinematography, these lenses keep weight and size to a minimum, while their specification is optimized for enhanced durability. The end result is a combination of performance and compact design at the highest level.

Dust-proof and splash-proof construction

The lineup features the same dust-proof and splash-proof construction as the SIGMA 150-600mm F5-6.3 DG OS HSM｜Sports.
