Well, I didn’t think we’d have to wait long after January’s Irix Cine 21mm T1.5 lens announcement before we’d see its photography counterpart, the Irix 21mm f/1.4. Now, the company has officially announced the new lens for Nikon F, Canon EF and Pentax K DSLR mounts. As with all of the Irix lenses, the optical makeup is identical to that of the cine version, although its exterior housing is quite different.
Like the T1.5 cine version, the f/1.4 variant is also a manual focus lens, in line with the rest of the Irix lineup, containing 15 elements in 11 groups with four ultra-low dispersion elements, four high reflectance elements and two aspherical elements. Irix says that the optical construction minimises distortion as well as coma, for you astrophotography types.
