Innovative technology
Combining capabilities specific to analogue photography with ingenious technology and solutions, the Irix 15mm f/2.4 is the perfect tool for both professionals and hobbyists. The new special features such as focus lock, infinity click and hyperfocal scale set a new level of manual lens functionality. Focus lock enables to lock the focus ring at any time enssuring the chosen settings. Hyperfocal distance scale gives information about the accessible range for depth of field for a given aperture simply and intuitively. When the focusing ring is set in the “infinity” position, there is a noticeable “click” (infinity click), making it easier to find the value without looking.

Extraordinary optical performance
The Irix 15mm f/2.4 meets the most demanding requirements of modern cameras. Thanks to sophisticated optical construction and special neutrino coating, colour aberration, ghosting and flare effects have been reduced to the absolute minimum, so the lens is ready to meet the requirements of the 50+ megapixel sensors of the newest cameras.

The complex optical system consist of 15 elements in 11 groups. Three of the lens elements have a high refractive index and two others have been made from extra-low dispersion glass. The construction also contains two glass aspherical lenses that are responsible for extremely high image quality and improving image brightness at edges, while minimizing distortions and aberrations at the same time.

With a minimum focusing distance of 0.28 metre and 9 rounded shaped aperture blades, the lens stands for supremely smooth out-of-focus areas. Working with a narrow depth of field it allows the user to fully enjoy the bokeh effect.

Resistant to extreme conditions
Irix 15mm f/2.4 lenses are made with extreme precision, allowing them to be used in even the harshest weather conditions. Each lens is equipped with a weather sealed construction that protects the interior against dust and moisture. Thanks to inner seals they are also protected from accidental water splashes.

Prepare for more and create
Despite its short focal length and large aperture, the Irix 15mm f/2.4 is equipped with not only a front filter mount, but also has a rear gelatin filter slot. The design of the lens allows the use of 95 mm screw-in filters at the front in the petal-shape lens hood and gelatin filters at the back of the lens. This ensures unlimited possibilities for image creation.

Personalize your view

Irix Blackstone: classic design meets maximum functionality, achieving the perfect match of innovative technology.
