Canon’s most compact 50mm lens, the EF 50mm f/1.8 STM has a rugged metal mount, plus an improved minimum focusing distance of 1.15 ft. (0.35m) and a maximum magnification of 0.21x. Offering sharp performance for the best in movies and stills, it’s a fixed focal length gem—the perfect lens for photographers and moviemakers to expand the creative possibilities with their EOS cameras. With an 80mm effective focal-length on APS-C cameras, 50mm on full-frame cameras, it’s an excellent prime lens for portraits, action, even night-time photography.
