Irix 15mm f/2.4 Firefly - Pentax K
Irix 15mm f/2.4 Firefly Pentax K is a manual-focus ultra-wide prime lens with a bright f/2.4 aperture. It was aimed at photographers who want a very wide field of view with a relatively compact, lighter build than the brand’s more premium Blackstone version. The Firefly body uses a composite shell and simple handling, with a geared focus ring and a separate aperture ring that make it well suited to landscape, architecture and night-sky work when precise framing matters. Optical performance is known for strong centre sharpness from good apertures and a characterful, distortion-controlled wide view for its class, though ultra-wide corners and close focusing are always more demanding. Because it is manual focus only, it rewards careful use and is less suited to fast-moving subjects, but on Pentax DSLRs it offers a distinctive full-frame ultra-wide option at a sensible used price. Check any used copy for smooth focus movement, aperture-ring operation, front/rear element marks, haze, fungus, dust and signs of impact, plus mount wear and proper infinity focus.
