Irix 15mm f/2.4 Firefly Pentax

An impressive optical performance and high-quality execution integrated into a lightweight and compact housing. Whether you are sailing, hiking, driving, or flying – the Irix Firefly 15mm f/2.4 makes your journey extraordinary. Whether capturing urban architecture or landscape images, the ergonomic focus ring helps you capture the perfect moment.

The front part of the lens is free of any engravings, prints, or other markings, eliminating unwanted reflections when using neutral density filters. Thanks to the sophisticated optical design and special Neutrino coating, chromatic aberration, imaging and color fringing, as well as lens reflections, are minimized to an absolute minimum. You can lock the focus ring at any time to secure your chosen setting. Precise and comfortable – a brilliant solution.

The hyperfocal distance scale simply and intuitively shows you the depth of field range depending on the aperture. For easier operation without optical control, you will hear a slight "click" sound when the ring is in the "Infinity" setting. Finally, you can instinctively operate your lens and direct your gaze and full attention to the composition of the image.

Irix lenses are manufactured with the highest precision. Each Irix lens is weather-resistant against dust and moisture, equipped with internal seals. This makes the lens even splash-proof. Despite the short focal length and large aperture, we not only offer a front filter thread accessible through a window in the lens hood, but we have also added a slot for gelatin filters at the back. This gives you even more options for your creative image creations.
