Product description
Announced Mar 16, 2016

The Irix 15mm F2.4 is an ultra-wide lens for Canon, Nikon and Pentax full-frame DSLRs. Its complex optical system consist of 15 elements in 11 groups. Three of the lens elements have a high refractive index and two others have been made from extra-low dispersion glass. The construction also contains two glass aspherical lenses that are responsible for extremely high image quality and improving image brightness at edges, while minimizing distortions and aberrations at the same time. It has a minimum focusing distance of 0.28 metre and 9 rounded shaped aperture blades.

The 'Firefly' model is the standard version, while the 'Blackstone' has a more durable body and engraved fluorescent markings. Both lenses are weather-sealed.
