Yongnuo 14mm f/2.8 Overview
Offering an impressive ultra wide-angle field of view, the Canon EF-mount YN 14mm f/2.8 from Yongnuo is a versatile prime well-suited for landscape, nature, and interior photography. The broad 114° field of view offers a creative perspective for working in both wide open spaces and tight interiors. Benefitting the ultra wide design is an advanced optical design, which makes use of ultra-low dispersion, aspherical, anomalous partial dispersion, and ultra-high refractive index glass to sufficiently control chromatic and spherical aberrations for high clarity and sharpness. A multi-coating has also been applied to suppress lens flare and ghosting for greater contrast and color neutrality. A DC motor affords quick and accurate autofocus performance and a switch lets you quickly change from AF and MF focusing methods. Additionally, a micro-USB port is located on the barrel of the lens to permit installing firmware updates for the lens.
