IRIX the innovative 15mm lens
for the most demanding professionals
The latest technology
tied up in a classic design
Have you ever had the dilemma of choosing between the newest technology and the most classical design? The Irix Blackstone 15mm f/2.4 prevents such an issue.
Classic design meets maximum functionality, achieving the perfect match of innovative technology. The durable aluminium and magnesium body ensures foolproof protection of your lens, even in extreme conditions. Engraved fluorescent markings enable easy operation in all lighting conditions to facilitate the perfect photo.
For a lightweight journey
The Irix Firefly 15mm f/2.4 is equiped with the same optical performance and high quality mechanism as the Blackstone, but implemented in a lightweight and handy design. Whether you sail, hike, drive or fly, the Irix Firefly will make your journey extraordinary.
The ergonomic focusing ring offers the freedom to capture the most ideal moment, whether it is big city architecture or wildlife scenery. Challenge accepted.
IRIX: well thought out to the smallest detail.
Ultra-wide angle lenses without compromise
Despite the short focal length and large aperture, we provide not only a front filter thread with a window in the petal-shape lens hood, but we also add a rear gelatin filter slot to give you even many more options in image creation.
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.
