Crisp, Fast, and Wide: Fstoppers Reviews the Irix 15mm f/2.4 Wide-Angle Lens

Meet the Irix 15mm f/2.4 Blackstone, a wide-angle lens designed for photographers who need a dependable lens even in extreme situations. The lens, coming to you from TH Swiss Company, first debuted in 2016 and is now widely available for Canon, Nikon, and Pentax mount systems. Irix does make two different versions of this lens: the Firefly which is the standard version of the lens, and the Blackstone which is the premium version of the lens. For the purposes of this review, I worked solely with the Blackstone version.
