A versatile ultra-wide prime lens, the Canon EF-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. Optically perfect, good condition, very durable build. TEXT or CALL: (647) 921-0507
