FAQs
What is the filter size for this lens?
The Sigma Cine 18-35mm T2 Zoom Lens has a standardized 82mm filter thread size.
Can I use this lens on a camera with an EF mount?
No, this lens features a PL mount and is designed exclusively for cameras equipped with a PL mount. It is not directly compatible with EF or other mounts without specialized adapters, which may not be available or recommended.
What does 'T2' mean for the aperture?
T2 refers to the *transmissivity* of light, which is a more accurate measure for cinema than F-stop. T2 is the effective maximum aperture, indicating how much light the lens transmits.
Is this lens parfocal?
Yes, the Sigma Cine Zoom lenses are designed to be parfocal, meaning the image remains in focus throughout the zoom range.
What is the benefit of the 180° focus and 160° zoom rotation angles?
These extended rotation angles allow for significantly more precise control over focusing and zooming compared to still photography lenses. This precision is crucial for smooth, accurate focus pulls and zooms during professional filmmaking.
How does the standardized color balance help?
Sigma's CCI (Color Consistency Index) standard ensures that the color rendition is consistent across different Sigma cine lenses. This greatly simplifies color grading and matching shots filmed with multiple lenses.
Is the lens suitable for handheld shooting?
While the lens is built to be durable, its weight and size are optimized for use with professional camera rigs, tripods, or gimbals. Handheld use is possible with appropriate support, but it is designed with cine-style shooting in mind.
Troubleshooting
Lens is not communicating with the camera.
This lens uses a PL mount and does not have electronic contacts. Ensure the lens is securely locked onto the PL mount. If you are experiencing issues with focus or zoom operation, check that the rings are moving freely and are not obstructed.
Image appears soft or lacks sharpness.
Ensure the lens is properly focused. Check that the aperture is not excessively wide open if maximum sharpness is required. Clean the front and rear lens elements with a microfiber cloth. Verify that the lens is seated correctly on the camera mount.
Zoom or focus rings are stiff or jerky.
Inspect the rings for any external obstructions. If the issue persists, do not force the rings. Contact Sigma support or a qualified lens technician for professional servicing. Avoid exposing the lens to extreme temperatures or moisture, which can affect mechanical components.
Color rendition seems inconsistent with other lenses.
This lens is designed with Sigma's CCI standard for consistent color balance. Ensure other lenses used in the same project also adhere to similar color standards or are within the CCI range. Proper white balance and color grading in post-production are essential for matching.

Setup, Compatibility & Care
Setup:
- Ensure your camera body has a PL mount.
- Carefully align the lens mount with the camera's PL mount index mark.
- Gently rotate the lens clockwise until it locks securely into place. Listen for an audible click.
- Attach any desired accessories, such as a matte box using the 95mm front diameter, or filters into the 82mm filter thread.
Compatibility:
- Camera Mount: Exclusively designed for cameras with a PL mount. Check your camera manufacturer's specifications for mount compatibility.
- Sensor Coverage: Suitable for full-frame sensors and other large formats, including Super 35mm.
Care:
- Cleaning Lenses: Use a soft lens brush to remove dust. For smudges, use a microfiber lens cloth and a small amount of lens cleaning solution applied to the cloth, not directly to the lens.
- Storage: Store the lens in its original case or a padded camera bag when not in use to protect it from dust, moisture, and physical damage.
- Handling: Avoid touching the lens elements with your fingers. Always handle the lens by its body or focus/zoom rings.
- Environmental: Protect from extreme temperatures, direct sunlight for prolonged periods, and moisture.
