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. With each ring and mount specially sealed to prevent water and dust from entering, this lens is ready for use in tough conditions. The unusually robust specification of the lineup allows the user to concentrate on shooting while significantly reducing the burden of maintenance.

100% metal body
The body is made completely of metal to stand up to tough professional use over the long term.

Luminous paint for enhanced visibility
The specification, gradation baseline and lens change indications all feature luminous paint to aid in changing the lens in the dark and other tasks.

Laser engraving for enhanced durability
Information on rings and elsewhere is laser-engraved for use over the long term. In addition, tape may be placed on gradations without fear of stripping away paint when it is removed.

Front

82mm filter size (For 24mm/35mm/50mm Lenses)
The filter size is standardized at 82mm, allowing users to use the same size of ND filter on different lenses. (Certain lens models are not compatible with 82mm filters).

95mm front diameter
The front diameter is 95mm, similar to that of other cine lenses and compatible with matte boxes. Compared to lenses in the same class, Sigma's cine lenses are more lightweight and compact.

Ring

Standardized gear positions
The positions of the gears in each ring are standardized, eliminating the need to adjust the follow focus, motor unit or accessories even when the lens changes.

0.8M gear pitch
Each lens has a 0.8M gear pitch, which is the standard for cine lenses, ensuring compatibility with existing accessories.

Silent ring stoppers
The stopper of each ring incorporates a damper made of a special resin, resulting in silent operation. While offering a satisfying lock feel, this feature eliminates any metallic sounds, allowing the user to shoot with confidence in a quiet area.

180deg. focus rotational angle
At 180deg., the rotational angle of the focus ring is more than double that of a still camera lens, making possible extremely high-precision focusing. Sigma has also optimized the cam for cine lenses for even easier long distance focusing.

Iris with full manual control
Featuring manual control capability, the iris ring offers smooth control without clicks. The T-stop display, which is standard in cine lenses, contributes to high-precision exposures. Just like a high-end cine lens, the rotational angle of the iris ring is 60 degree.

Linear iris ring
The linear iris ring gives users the same rotational angle per T-stop for direct, intuitive control.

Mount

Mount with electronic contacts
The mount with electronic contacts allows the lens to communicate important information to the body (focal length, shooting distance, aperture etc).

Accessories

Dedicated lens support foot
Coming as a standard accessory with all lenses in the lineup, the lens support foot helps minimize load on the camera body while enhancing mount stability. The height of the seating surface is designed for compatibility with other accessories. Even though the lens is compact, its robust design offers two different screw holes for this accessory to increase user options.

Cine-style front lens cap
All lenses come complete with a conventional cine-style front lens cap.
