Irix have matched timeless design decisions with maximum functionality to offer you the perfect piece of durable technology. The solid aluminium and magnesium body ensures foolproof lens protection, even in the most extreme situations. Easy operation is achieved in all lighting conditions thanks to our engraved fluorescent markings, just one of our many ingenious, photographer-friendly developments.

Neutrino coating

Thanks to sophisticated optical construction and special neutrino coatings, colour aberration, ghosting and flare effects have been reduced to the absolute minimum.

Get more focused with focus lock

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.

Focus calibration

Irix 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.

Extreme weather resistance

Irix know how important it is to protect your gear. The 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.
