Prime Lens. Rugged Metal Mount. Minimized Ghosting and Flare. Filter Diameter: 49mm
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. Lens coatings helps render images with excellent colour 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
Improved focus ring placement makes manual focus adjustments a breeze. Improved minimum focusing distance of 1.15 ft. (0.35m). Maximum magnification of 0.21x.
