Irix 15mm F2.4 Firefly lens


The new ultra wide-angle, rectilinear manual lens designed for DSLR cameras guarantees exceptional optical performance. Irix Swiss Design stands for minimalism in style while maintaining maximum functionality. It is a perfect mixture of European design combined with Korean precision. The same look and feel of all products in the Irix family. The same consistency, product packaging and complementary elements, all perfectly shaped and fitting one another.


The Irix 15mm f/2.4 lens is designed to deliver the best optical performance and match full frame DSLR cameras demands. Providing a focal length of 15mm, this new lens model is ideal for outdoor and indoor photography whether it is photojournalism, landscapes or architecture.


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.

The retaining ring of the frontal lens is free from engraving, printing or any other form of marking. This therefore prevents unwanted internal reflections when using high density filters.


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.


You can lock the focus ring at any time securing the setting that you choose. Precision, comfort and ingenious solutions.


The hyperfocal distance scale simply and intuitively gives information about accessible range for depth of field for a given aperture. When the ring is set in the “infinity” position, there is a noticeable “click”, making it easier to find the value without looking. Now you can fix your eyes on the image and concentrate on the composition.


While IRIX has made every effort to ensure that each lens leaving the factory has been properly calibrated, the lens is designed to allow you the unique opportunity to calibrate the lens for a particular model of your camera. This ensure your focusing is always accurate to your expectation.

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. Removable Hood allows installation of lens filter at ease too.


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.


IRIX 15mm F2.4 is designed to ensure top notch optical precision and clarifty. To achieve this High Refractive, Extra Low Disperson and Aspherical elements are used.


Note: The Firefly series is optically identical to the Blackstone series. The Blackstone series has anti-scratch finishing, metal focusing ring and durable aluminium and magnesium body for foolproof protection of your lens. The Blackstone series has engraved fluorescent UV markings that reflect the light enable easy operation in all lighting conditions.
