FF ZOOM LINE

24-35mm T2.2

Compatibility

Compatibility has been confirmed with each brand of cinema cameras.

Compatible for full-frame

This lens is designed and optimized for full-frame cinematography.

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.

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 type of dust and splash resistant structure* as Sigma Sports line lenses. 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).

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.

82mm Filter Size  ①

The filter size is 82mm, allowing users to use the same size of ND filter on different lenses.

95mm front diameter  ②

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 positions  ③ ④ 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 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 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 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.

EF and E

Available lens mounts are Canon EF mount and Sony E-mount. All lenses in the lineup may also be used on still cameras with the compatible mount for outstanding DSLR and mirrorless movie shooting.

Mount with electronic contacts  ⑥

Enhanced EF mount*  ⑥

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

Dedicated lens support foot  ⑦

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.

MOUNT CONVERTER MC-11

The Sigma MOUNT CONVERTER MC-11 allows Sigma SA mount and Sigma's Canon EF mount interchangeable lenses to be used on Sony E-mount cameras.

MOUNT CONVERTER MC-21

The Sigma MOUNT CONVERTER MC-21 allows Sigma SA mount and Sigma's Canon EF mount interchangeable lenses to be used on L-Mount cameras.
