Promising new full-frame ultra-wide prime

£543/$678

www.irixlens.com Fresh from its first optic – a 15mm f/2.4 – lens newcomer Irix is going wider with its follow-up offering. Incorporating no less than four high-refractive elements, two ED elements, and three aspherical lenses, Irix is claiming minimal distortion from this rectilinear ultra-wide. The lens is available in two flavours: Blackstone boasts a premium aluminium-magnesium alloy barrel with engraved markings, while the cheaper Firefly version uses a plastic barrel to keep weight down to 730g.
