Sigma 85mm T1.5 FF Cine

The Sigma 85mm T1.5 FF Cine is a high-performance cinema prime lens designed for full-frame sensors. It features a constant T1.5 aperture, providing excellent low-light capability and shallow depth of field control. The lens follows a standardized design with consistent gear positions for focus and iris, making it compatible with industry-standard follow focus systems and matte boxes. The optics are based on the Art series, offering 8K-compatible resolution with a natural rendering of skin tones and smooth highlights. Check the focus and iris gears for any signs of chipped teeth or uneven resistance throughout their rotation. Ensure the 95mm front diameter is perfectly circular and free from dents to allow for easy matte box mounting. SDS inspects the internal glass for any signs of fungus or haze and verifies that the iris blades are snappy and oil-free. We also check the mount for any play, as cinema lenses often undergo frequent mounting and unmounting.
