Sigma 40mm T1.5 FF High-Speed Prime Lens for Sony E, Meter

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.
