Canon USA announced the brand new EF 50mm f1.8 STM lens this morning. This lens will be an exciting replacement for the previous EF 50mm f1.8 II lens, and retailing at the same price–$125.99. Updates to the design include a metal mount, replacing the plastic design of the previous generation, and adds the stepping motor (STM) for nearly silent, smooth autofocus during video recording.
According to Canon: “Compact and lightweight-an outstanding walk-around lens-Canon’s EF 50mm f/1.8 STM is a great entry into the world of EOS prime lenses. 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 nighttime photography. Its bright maximum aperture of f/1.8 helps it not only to excel in low light, but also to capture gorgeous, sharp images and movies with beautiful background blur thanks to its circular 7-blade design. An updated lens arrangement with new lens coatings helps render images with excellent color balance, plus minimized ghosting and flare. Performance is brilliant, with a stepping motor (gear-type STM) to deliver near silent, continuous Movie Servo AF for movies plus speedy, smooth AF for stills. A redesigned exterior with improved focus ring placement makes manual focus adjustments a breeze. 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.”
