Powerful standard lens suitable for everyday shots. Image sensor standard: APS-C. Lens mount: Sony E-Mount. Focus: Automatic. Filter thread diameter: 49 mm. Ultrasonic digital stepping motor. USB-C port for firmware updates. The Yongnuo 50 mm f/1.8S DA DSM II lens offers fast and quiet autofocus performance for both photos and videos. It features an anti-fouling fluorine coating that prevents oil and water from affecting the front lens. With a large aperture of f/1.8 and a seven-blade diaphragm, the 50 mm lens effortlessly transforms out-of-focus areas into beautiful, soft bokeh. At the same time, you have better control in low light conditions and can work with longer shutter speeds to achieve sharper quality. The lens is designed for Sony E-Mount cameras in APS-C format but corresponds to a 75 mm full-frame equivalent. Package includes: 1x Yongnuo YN50mm F1.8S DA DSM II, 1x lens hood, 1x front lens cap, 1x rear lens cap.
