The Yongnuo YN 50mm f/1.8S DA DSM lens has a fixed focal length and is designed for Sony E-mount cameras with APS-C sensors. The DSM digital stepping motor delivers fast, quiet, and accurate autofocus for both photos and videos. Its optical design includes a low-dispersion element to reduce chromatic aberration and a Nano multilayer coating to control reflections and ghosting.
The 7-blade aperture creates a soft bokeh effect, while the coating repels oil, water, and dust for easier cleaning. The metal mount is chrome-plated and the contacts are gold-plated. The built-in USB-C port supports firmware updates.
