Irix 15mm f2.4 Blackstone Nikon

Iris 15mm is the perfect right-angle, straight-angle manual focus lens for DSLR cameras. With a focal length of 15mm, this lens is ideal for outdoor, nature and astro or architectural photography.

The optical construction of the Irix Blackstone wide-angle lens is outstanding and meets the most demanding requirements of modern cameras. 15 elements in 11 groups include three elements of high-index glass and two of extra-low dispersion glass. Two aspherical lenses provide extremely high image quality and improve image brightness at the edges while minimizing distortion and aberration.

The new special features such as focus lock, infinity click and hyperfocal scale set new functions for manual focus lenses. Thanks to the sophisticated optical design and the special neutrino coating, color aberrations, ghosting and flare effects have been reduced to an absolute minimum.

With a minimum focusing distance of 0.28 meters and 9 rounded aperture blades, the lens stands for extremely smooth, out-of-focus areas. The design of the lens allows the use of 95mm screw-in filters in the front of the petal-shaped hood and gelatin filters in the rear of the lens.
