A minimal distortionwide 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.
Resistant to extreme conditions
Irix lenses are made with extreme precision. Each Irix lens is equipped with a weather sealed construction that protects the interior against dust and moisture. Thanks to inner seals, our lenses are also protected from accidental water splashes.
We appreciate beauty in every detail
At the rear you can slot in a gelatin filter to give you even many more options in image creation.
Thanks to sophisticated optical construction and special neutrino coatings, colour aberration, ghosting and flare effects have been reduced to the absolute minimum.
You can lock the focus ring at any time securing the setting that you choose. Precision, comfort and ingenious solutions.
Infinity click and hyperfocal scale
The hyperfocal distance scale simply and intuitively gives information about accessible range for depth of field for a given aperture. When the ring is set in the “infinity” position, there is a noticeable “click”, making it easier to find the value without looking. Now you can fix your eyes on the image and concentrate on the composition.
Ultimate precision to sharpen your imagination. We have made every effort to ensure that each lens leaving the factory has been properly calibrated. However, for your comfort Irix lens provides you the unique opportunity to calibrate the lens for a particular model of your camera.
