About Sigma T1.5 Cine

How SIGMA CORPORATION revolutionized the cinema lens market with its SIGMA CINE LENSES is a testament to their commitment to high-quality, professional-grade cinematography equipment. Designed specifically for the demands of digital film production, these lenses cater to the increasing need for higher resolution, compatible with the latest high-resolution digital cinema cameras.

The SIGMA CINE LENSES are a product of SIGMA's innovative production system, which is geared towards the mass production of high-performance lenses for ultra-mega-pixel shooting. The FF HIGH SPEED PRIME LINE, a part of this impressive lineup, ranges from 20mm to 85mm, with all five lenses boasting a fast maximum aperture of T1.5. These lenses are compatible with full-frame sensors and offer superior resolution, outperforming other high-end prime sets while maintaining a compact design.

With the FF High Speed Prime Line, cinematographers can shoot a variety of cuts without needing to adjust the lighting, bringing a consistent level of light to the production and offering greater consistency in the film's look, color, and contrast before post-production.

Each CINE lens model is weatherproof and features luminous paint markings for easy operation in low light conditions. They offer a long focus rotation of 180 degrees, guided by cams for smooth operation and accuracy. The design includes standardized essentials such as an 82mm front for ND filters, a 95mm front diameter for matte box use, and standard gear positions for accessories like follow focus.

The lenses also include a manual linear iris control and electronic mounts that provide vital camera metadata. Each lens is meticulously manufactured and inspected in the Sigma factory located in Aizu, Japan, ensuring compliance with all specifications and outstanding lens performance.

SIGMA lenses are renowned for their fine design, precise manufacturing, and rigorous inspection process. They are equipped with SIGMA's own A1 proprietary Modulation Transfer Function (MTF) measuring system using 46-megapixel Foveon direct image sensors, ensuring high-performance shooting and ultra-high resolution.

The lenses are designed to minimize flare and ghosting and enhance contrast in backlit conditions. They deliver sharpness combined with an outstanding bokeh effect, meeting the high demands for image quality in still photography. All lenses in the lineup comply with SIGMA's CCI standard, ensuring standardized color balance and making color correction easy.

The build quality of these lenses is lightweight and compact, with specifications optimized for enhanced durability. They feature dust-proof and splash-proof construction, with each ring and mount specially sealed to prevent water and dust from entering. The lenses also feature luminous paint for enhanced visibility in low light conditions, and information on rings and elsewhere is laser-engraved for long-term use.

SIGMA's commitment to providing robust accessories enhances the convenience and ease of use of the new lens lineup. The Mount Conversion Service, available for its new cine lenses, allows users to convert their lenses to and from EF and E-mounts, ensuring that SIGMA lenses remain a valuable asset even if the camera system changes.

In conclusion, the SIGMA CINE LENSES are a testament to SIGMA's commitment to providing high-quality, professional-grade, and reliable cinematography equipment. They are versatile, durable, and designed to meet the demands of modern digital film production.

Sigma T1.5 Cine Features

  • 100% metal body: The body is made completely of metal to stand up to tough professional use over the long term.
  • 82mm filter size: The filter size is standardized at 82mm, allowing users to use the same size of ND filter on different lenses.
  • 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.
  • 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.
  • 180½ focus rotational angle: At 180½, 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 60½.
  • Linear iris ring: 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 with electronic contacts: The mount 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.
  • Dedicated lens support foot: The provided 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.
