85mm T1.5 FF

The lineup covers everything from wide angle to telephoto. Produce an entire work with Sigma lenses alone.

Compatibility has been confirmed with each brand of cinema cameras.

Available in T1.5 or T2. These options enable cinematographers to realize a wide range of expressive goals.

This prime lens lineup comes with electronic contacts that supports Cooke’s /i Technology communication protocol for Art Prime PL mount lenses. By using an /i Technology-compatible cine lens with a cine camera that supports the same protocol, users can see and record lens metadata such as focus distance, focal length, and aperture. This helps streamline compositing in the post production process. This is particularly suitable for the latest forms of filmmaking, such as VFX, that call for detailed shooting data.

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.

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.

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.

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

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.

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.

The lineup features the same dust and splash resistant structure* 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.

* Although this construction allows the lens to be used in light rain, it is not the same as being waterproof.

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

The specification, gradation baseline, and lens change indications all feature luminous paint to aid in changing the lens in the dark and other tasks. Moreover, it can be converted to FULLY LUMINOUS versions with rings whose numbers and gradations are finished with luminous paint(charges apply).

Conversion to Fully Luminous Version

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.

Filter Size  (1)
The filter size is standardized at Φ82mm or Φ86mm, allowing users to use the same size of ND filter on different lenses.

*Some models are not compatible with filters

・Φ82mm：24mm T1.5 FF~50mm T1.5 FF, 135mm T2 FF

・Φ86mm：65mm T1.5 FF, 85mm T1.5 FF

・Not compatible：14mm T2 FF, 20mm T1.5 FF, 105mm T1.5 FF

95mm front diameter  (2)

For the 20mm～85mm T2 FF, 135mm T1.8 FF lenses, 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.

For the Sigma 14mm T2 FF, CLAMP-ON RING 162MM COR-11 is available, and It extends the front diameter to 162mm.By attaching it to wide-angle matte box compatible with 6.6″ x 6.6″ in. square type filters such as the ARRI LMB-6 (2-stage) , it will allow cinematographers to film on full frame cameras without causing vignetting.

Standardized gear positions   (3, 4 and 5)

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   (3, 4, and 5)

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

Silent ring stoppers   (3, 4 and 5)

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.

180° focus rotational angle  (3)

At 180°, 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.

160° zoom rotational angle  (4)

At 160°, the rotational angle of the zoom ring is more than double that of a still camera lens, making possible extremely high-precision zooming.

Iris with full manual control   (5)

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°.

Linear iris ring   (5)

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

Selectable focus ring with feet or meter graduations

Based on user needs, a focus ring with either feet or meter graduations may be selected. For a small charge, Sigma can also convert the ring from one type to the other after purchase.

Mount Conversion Service

Seeing lenses as valuable assets, Sigma now makes the Mount Conversion Service available for its new cine lenses. Successfully implemented for their still photography camera lenses, this service allows users to convert their lenses to and from EF and E-mounts (charges apply). If the camera system changes, it is possible to simply convert the mount system to continue using the high-performance Sigma lenses.

Note: The Mount Conversion Service is not available for PL mount lenses.

PL/i, Canon EF and Sony E-mount
Selectable mounts available are the PL/i, Canon EF mount and the Sony E-mount (used on the Sony FS and FX series). All lenses in the lineup may also be used on still system cameras cameras with the compatible mount for outstanding movie shooting.

Mount with electronic contact

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

Enhanced EF mount*

The hole for the stopper pin has been strengthened with a separate part to minimize loosening over time and enhance long-term use.

*Only applicable for Canon EF mount

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.

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