Irix 11mm f/4.0 Firefly Pentax

Extreme wide-angle lens for full-frame cameras with a field of view of 126°. Four high-refractive, two ED, and three aspherical lenses ensure minimal distortion of only 3.13%. Unique in its class!

The Irix Firefly offers the same optical performance as the Blackstone variant but is integrated into a lighter construction. Whether you're hiking, traveling, flying, or simply need to keep the weight down, the Firefly will be your first choice. Its ergonomic design and non-slip rubber coating make this lens even more practical. The hyperfocal distance scale intuitively shows you the depth of field range based on the aperture. For easier operation without optical control, you'll hear a slight "click" sound when the ring is in the "Infinity" setting. Finally, you can operate your lens instinctively and focus your gaze and full attention on the composition of your image. A lockable focus ring, weather-resistant protection against dust and moisture, an infinity click, and a rear filter slot: all these features combined in a solid aluminum housing make the Irix 11mm lens an indispensable companion for landscape, architecture, night sky, and extreme photography.

As photographers, we know how important it is to protect your gear. Therefore, every Irix lens is equipped with weather-resistant seals. Enjoy your trip with the confidence that we have taken every measure to protect your lens from moisture, dust, and dirt.
