A compact normal-length prime designed for Canon EF-mount DSLRs, the YN 50mm f/1.8 Lens from Yongnuo pairs the classic 50mm focal length with a bright f/1.8 maximum aperture to suit working in a variety of situations. Multi-coated glass elements reduce the effects of lens flare and ghosting for greater contrast and maintained color accuracy. An AF/MF switch on the lens barrel permits quick switching between focusing methods, and the lens can focus as closely as 1.5' to suit photographing close-up subjects. Additionally, gold-plated contacts permit working with all exposure modes as well as transferring lens information to the EXIF data. A tried-and-true lens construction with design enhancements to benefit handling, this lens is an ideal walk-around lens for everyday shooting.Features Prime normal-length lens designed for full-frame format Canon EF-mount DSLRs Bright f/1.8 maximum aperture offers increased control over depth of field Multi-coated glass elements increase contrast and maintain color accuracy by reducing flare AF/MF switch on the lens barrel allows you to select focusing methods Seven-blade diaphragm contributes to a smooth out-of-focus quality Gold-plated electronic contacts convey EXIF data and also permit working M, Av, Tv, and P shooting modesSpecifications Focal Length: 50mm Maximum Aperture: f/1.8 Minimum Aperture: f/22 Optics: All Glass Multicoated Elements/Groups: 6/5 Format Compatibility: Full-Frame Digital Sensor / Canon (APS-C) Angle of View: 46 Minimum Focus Distance: 17.72" (.45 m) Magnification: 0.15xIncludes Yongnuo YN50mm F1.8 Prime Lens Yongnuo Front and Rear Lens Cap Yongnuo Manual Yongnuo 1 Year Warranty.
