IRIX
Extreme weather resistance
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.
Intelligent filter options
We offer you excellent wide-angle lenses with front and rear filter options. Our lenses feature an ingenious way to easily access a rotatable filter through use of a window on the petal-shaped lens hood. Next to this, we have also included a rear filter slot for gelatin filters, offering you even more opportunity for filter use.
