Lens Description: A versatile ultra-wide prime lens, the Nikon F-mount 11mm f/4 Firefly Lens from Irix balances a sophisticated optical design with a lightweight, durable physical construction. Aspherical, extra-low dispersion, and high-refractive index elements are used to suppress color fringing, chromatic and spherical aberrations, as well as unwanted distortion, and also contribute to producing a high degree of sharpness and clarity. Additionally, a Neutrino coating has been applied to limit lens flare and ghosting for improved contrast and color accuracy when working in strong lighting conditions.
Photography Life Review Summary: This is a lens for rather special purposes, I do not recommend starting with this lens to anybody who has not photographed with any wide angle yet. Creative and advanced photographer looking for new tools and perspectives may feel attracted to this lens. Read the full IRIX 11mm f/4 Firefly Review by Photography Life.
