As promised in a teaser shared two days ago, optics manufacturer Irix has announced a new 21mm T1. 5 lens designed for full-frame camera systems. The Irix Cine 21mm T1. 5 lens is constructed of 15 elements in 11 groups, including four extra-low dispersion elements, four high-refractive elements and two aspherical elements.
This design produces a 43. 3mm image circle compatible with sensors from full-frame all the way down to 1/3” sensors. The lens features a T1. 5 through T16 aperture range, uses an 11-blade aperture diaphragm and has a minimum focusing distance of 30cm (11. 8”).
Both the clickless aperture and focus rings feature a 180-degree rotation angle and use the standard Mod 0. 8 M rings with 117 teeth for compatibility with most any follow-focus system. Irix says the lens is resistant to rain, sand, snow or dust and the distance markings are filled with UV-reactive paint for easier viewing in low-light environments.

This new 21mm T1. 5 lens is available for Arri PL, Canon EF, Canon RF, L, MFT, Nikon Z and Sony E mount camera systems. Sizing slightly varies based on the lens mount, but Irix has designed it to be almost exactly the same size as its 30mm and 45mm T1. 5 lenses in this lineup for easier swapping of lenses when you have a camera rigged up. Weight also varies slightly, but the lens weighs between 1054g (2. 3lbs) for the MFT mount version and 1229g (2. 7lbs) for the Nikon Z mount version.
The Irix Cine 21mm T1. 5 lens will come with a carrying pouch as well as front and rear end caps. It’s expected to retail for €1,195 / $1,350 when it becomes available to order through Irix’s online shop and at authorized Irix retailers.
