Designed for up to 8K cine-style image capture, the Canon RF-mount 21mm T1.5 Cine Lens from IRIX produces a distortion-free, wider-angle look that is compatible with sensor sizes up to full-frame 35mm. External features include a 95mm front diameter, 0.8 MOD gears, luminous focus marks in feet, and a detachable 1/4"-20 support foot. Internally, 11 blades produce smooth, rounded bokeh, and four seals protect against inclement weather and dust. A fast T1.5 maximum aperture enables the IRIX 21mm T1.5 Cine Lens to capture images in low light conditions without the need for super-high ISO settings.

This lightweight, aluminum/magnesium alloy lens produces smooth, rounded bokeh, color, and contrast that matches the T1.5 30 and 45mm primes in the IRIX Cine series. An adaptive focus ring delivers smooth focusing whether used manually or with a lens motor.
