Irix 15 mm f-2.4 Firefly

The Irix 15mm Firefly is a manual, super-wide-angle lens that allows you to include much more of the scene for a greater sense of space and incredible effects. It's the perfect lens for landscape, architectural and even interior photography. This versatile lens will adapt to every situation and the results are impressive, to say the least. The built-in hyperfocal distance scale gives you precise information about the depth of field for each shot. The ergonomic focusing ring incorporates a convenient click-stop for the infinity setting. An innovative focus lock lets you easily set the focus anywhere on the scale and keep it there for consistently repeatable results and to help avoid focus drift. With a minimum focusing distance of 11.02" (0.28m), you can get in close to your subjects for great wide-angle effects.

Irix has created the Firefly lens with a weather-resistant exterior and inner seals, so you can use it in all weather conditions. Thanks to this construction, your Firefly lens is protected from accidental water splashes, rain, snow, dust and other airborne particles. This makes it the perfect glass for photographers who need to work in all possible conditions.

The optical construction of the Irix Firefly wide-angle lens is superb, meeting the most demanding requirements of modern cameras. 15 elements in 11 groups include three elements of highly refractive glass and two of extra-low dispersion glass. Two aspherical lenses provide extremely high image quality and improve image brightness at the edges, while minimizing distortion and aberration. Irix 15mm wide-angles also feature 9 rounded diaphragm blades, perfect for beautiful bokeh at wide aperture settings.
