Description
The Irix 21mm f/1.4 is a wide angle full frame prime lens for use with Canon EF, Nikon F and Pentax K mount camera systems. This lens features a electronic aperture control allowing the aperture to be controlled from the camera, but is still a manual focus lens. It also features a focus lock function.
The optical construction of the Irix 21mm f / 1.4 lens is based on 4 ultra-low dispersion glass elements, 4 high reflectance and 2 aspherical elements. There are a total of 15 elements in 11 groups.
The lens is equipped with special seals that prevent the ingress of moisture and dirt into its interior. A special bayonet mount gasket also protects the mirror chamber of the camera.
The lens housing is a continuation of the Dragonfly manufacturing standard known from the earlier Irix models. Its most important aspects are reinforced internal structure based on metal elements, scratch-resistant lens finish, anti-skid focusing ring with a special finish and engraved markings filled with UV-reactive paint.
