The Sigma Cine 40mm T1.5 FF Prime is designed for professional cinematographers and production crews who demand superior optical precision for large-format sensors. It excels by providing high-resolution clarity up to 8K, yet the primary caveat for users is that it is a specialized tool requiring a PL-i mount camera system to unlock its full metadata capabilities.

Yes, this lens is designed specifically for large-format sensors, including full-frame cinema cameras.
This lens requires a PL-i mount. You may be able to use a high-quality lens adapter, but metadata communication may be lost.
/i Technology transmits metadata such as focus distance, aperture, and focal length to the camera, which is saved with your video files to assist in post-production and VFX.
Yes, the optical performance of this series is specifically optimized to meet the high-resolution requirements of 8K cameras.
Use a gentle lens brush to remove particles and follow up with an optical-grade lens cleaning solution and a microfiber cloth.
This specific model features metric (meter) focus ring markings.
Verify that your camera supports Cooke /i Technology and that the pins are clean and fully seated in the mount.
Ensure the focus ring is not obstructed and verify the metric calibration against your focus puller's monitor output.
Use a professional air blower to clean the rear and front elements; do not use compressed air that can leave residue.
To ensure optimal performance, verify that your camera's PL mount supports /i Technology communication pins. When mounting the lens, ensure the pins align correctly to enable data transmission. For care, always store the lens in a dust-free environment with front and rear caps secured. Avoid touching the optical glass directly, and use a professional lens-cleaning kit to remove smudges. Because of the precision mechanical construction, professional calibration service is recommended every 12 to 24 months depending on usage frequency.
