All 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, Irix lenses are also protected from accidental water splashes. No matter the journey, you can be confident that these weather sealed lenses will offer you maximum resistance to the extremes.

Blackstone, the premium version, has a durable body made from an aluminium-magnesium alloy, which ensures foolproof protection of your lens, even in extreme situations.
