Ring

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

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.

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.

Front

82mm filter size* [1]

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.

Mount

PL, EF and E*

Available lens mounts are the Canon EF mount, which is used on the majority of digital cinema cameras, and the Sony E-mount, which is used on the Sony FS series. All lenses in the lineup may also be used on still cameras with the compatible mount for outstanding DSLR movie shooting.
*24-35mm T2.2 FF is not available in PL mount.

Mount with electronic contacts [6]

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

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

Accessories

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.

Robust accessory selection

The USB DOCK allows the user to connect the lens to a computer and update firmware, while the MOUNT CONVERTER MC-11 allows users to enjoy the high performance of SIGMA’s Canon EF mount interchangeable lenses with the Sony E-mount camera body. These and other accessories further enhance the convenience and ease of use of the new lens lineup.
