Lenses compatible for full-frame

State-of-the-art resolution meets the classic “look”, "Classic Art Prime"

The FF Classic Prime Line incorporates more non-coated optical elements to achieve unrivaled expression. It retains the high resolution capability that Sigma CINE LENS is well known for, and offers a unique combination of low contrast and artistic flare/ghost in the image. The “look” that FF Classic Prime Line can offer will enable cinematographers to explore new possibilities in movie creation.

/i Technology-compatible

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.

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.

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.

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 and Splash Resistant Structure*

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.

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. 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

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.

Filter size①

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 T2.5 FF~50mm T2.5 FF, 135mm T3.2 FF

・Φ86mm：

65mm T2.5 FF, 85mm T2.5 FF：M 86 x 1.0 mm

・Not compatible：

14mm T3.2 FF, 20mm T2.5 FF, 105mm T2.5 FF

95mm front diameter②

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.

Standardized gear positions③④⑤

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 pitch③④⑤

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

Silent ring stoppers③④⑤

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 angle③

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.

Silent ring stoppers③④⑤

180° focus rotational angle③

160° zoom rotational angle④

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 control⑤

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 ring⑤

The 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.

Dedicated lens support foot⑦

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

With cutting-edge technology, Sigma's new "Classic Art Prime" offers unrivaled expression for artists.

FF High Speed Prime Line has been offering the highest resolving power in its class, that is compatible with 8K shooting with large format sensors, while achieving outstanding compact design. Based on this product line, the FF Classic Prime Line incorporates more non-coated optical elements to achieve unrivaled expression. It retains the high resolution capability that Sigma CINE LENS is well known for, and offers a unique combination of low contrast and artistic flare/ghost in the image. As with all other lenses from the FF High Speed Prime Line, it creates beautiful bokeh effects to improve creativity.
FF Classic Prime Line has implemented newly developed coatings on the glass elements and offers consistent T value across the lineup (14mm and 135mm at T3.2 and the rest of the lenses at T2.5). This will greatly contribute to the effective workflow in postproduction. Furthermore, it is compatible with the communication protocol of Cooke “/i Technology”, thus an ideal tool for shooting and editing with the latest technology, such as VFX. A special coating is implemented on the front and rear elements so that the lens durability is ensured as with all other cine lenses from Sigma.
“Classic Art Prime” is a new solution from Sigma that is required for the most advanced technology for classical expression. The “look” that FF Classic Prime Line can offer will enable cinematographers to explore new possibilities in movie creation.

The highest quality, in every detail. "Aizu-nuri" featured

Sigma always pursues “the best materials and technology” without compromise to achieve the highest quality. The Classic Art Prime series is no exception, and the policy is even alive in the logo. To identify the lens in the shooting scene using a wide variety of lenses, and to provide the texture and quality suitable for professional tools, and the durability to support the harsh environment of cinema lenses. Aizu-nuri (Aizu lacquering) was the solution for the “Classic” logo. Fortunately the best technique was at our production site, Aizu.
