IRIX 15mm f/2.4 Firefly
The 15mm f/2.4 prime uses 15 elements including two aspherical, two ED, and Neutrino coating to suppress aberrations and flare, all in a weather-sealed magnesium housing with damped manual focus. Luminous depth-of-field markings and a 1:2 maximum magnification enable low-light precision, while its 95mm front and rear gelatin filter support attachment flexibility. It’s best for Nikon F landscape and architectural photographers who need a durable, all-weather ultra-wide prime with critical manual focus control.
