Irix 11mm f/4.0 Blackstone Pentax

Extreme wide-angle lens for full-frame cameras with a field of view of 126°. A low distortion of only 3.13% is achieved through 4 high refractive, 2 ED, and 3 aspherical lenses. Unique in its class!

Have you ever faced the choice between the latest technology and classic design? The Irix Blackstone 11 mm f/4.0 does not force you to make compromises. Classic design meets maximum functionality, achieving a perfect interplay with innovative technology. The robust aluminum/magnesium housing provides absolute protection for your lens, even under extreme conditions. Engraved, fluorescent scales allow for better readability in low light conditions. The hyperfocal distance scale intuitively indicates the depth of field range based on the aperture. For easier operation without optical control, you will hear a slight "click" sound when the ring is in the "infinity" setting. Finally, you can instinctively operate your lens and focus your gaze and full attention on the composition. A lockable focus ring, weather-resistant protection against dust and moisture, infinity click, and a rear filter slot: all features combined in a solid aluminum housing make the Irix 11 mm lens an indispensable companion for landscape, architecture, night sky, and extreme photography.

As photographers, we understand how important it is to protect your gear. That’s why every Irix lens is equipped with weather-resistant seals. Enjoy your trip with the assurance that we have taken all measures to protect your lens from moisture, dust, and dirt.
