A minimal distortion wide angle lens-unique in its class

Our 11mm lens is an extremely wide Full Frame rectilinear lens with a 126° angle of view. 4 high refractive lenses, 2 ED lenses and 3 aspherical lenses guarantee minimal distortion, as low as 3.13%, making our 11mm f/4.0 lens absolutely unique in its class.

A lightweight option with no optical compromises

Our Firefly lens offers the same optical performance and high quality mechanism as our Blackstone, but its ultra lightweight construction makes it the perfect choice for hikers, travellers, or anyone who simply likes to pack light. The ergonomic, anti-slip, rubber coated focus ring makes for a practical, user-friendly lens. This lightweight option is ideal for on the go photography, without any compromise on optical quality.

Extreme weather resistance

We know how important it is to protect your gear. Our Irix lenses are made with phenomenal precision. Each Irix lens is equipped with a weather sealed construction which protects the interior against dust and moisture. Thanks to inner seals, our lenses are also protected from accidental water splashes. No matter the journey, you can be confident that our weather sealed lenses will offer you maximum resistance to the extremes."
