Irix 15mm f/2.4 Σταθερός Ευρυγώνιος Φακός για Sony E Full Frame

With a 110° diagonal angle of view and a bright f/2.4 maximum aperture, the Irix 15mm f/2.4 captures expansive, dramatic perspectives on full-frame Sony E-mount cameras. The advanced optical design—15 elements in 11 groups including 3 HR, 2 ED, and 2 aspherical elements—ensures edge-to-edge sharpness and minimal distortion, while Irix's Neutrino coating suppresses flare and ghosting for high-contrast images even in challenging light.

Overview

Built for landscape, architecture, astrophotography, and interior photography, the Irix 15mm f/2.4 is a manual focus prime lens that combines rugged construction with precise optical performance. Its all-metal aluminum-magnesium alloy barrel is weather-sealed at three critical points, protecting against dust and moisture. The lens features a smooth, well-damped focus ring with a focus lock mechanism, hyperfocal scale, and depth of field markings for quick zone focusing. A rear gel filter slot accepts 30x30mm filters, complementing the large 95mm front filter thread.
