The wide f/1.8 aperture lets in more than 8x the amount of light compared to the standard zoom lens that is provided with your EOS. This results in sharper images with less motion blur and reduced need to use flash in dimly lit conditions so you can easily capture the atmosphere of a low light environment. The 50mm focal length allows you to fill the frame with your subject from a comfortable distance making it a great lens for portraits. A similar perspective to the human eye and its compact size make the EF 50mm f/1.8 STM a great everyday lens to always carry with your EOS camera. The near-silent STM (Stepping Motor) technology focuses extremely quickly when shooting photos, so you can react suddenly to capture fleeting moments. Creating high quality movies is easier with STM as it delivers steady and quiet continuous focusing, so your movies are smooth, and soundtracks only capture the surrounding sounds and not the noise of a focusing motor. The EF 50mm f/1.8 STM replaces the popular EF 50mm f/1.8 II lens which was affectionately known for giving outstanding picture quality at an affordable price. This latest version gives the same stunning photo quality but with a fast, near-silent focus motor and a more robust build that belies its price. FROM THE MANUFACTURER EF 50MM F/1.8 STM 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.
