Yongnuo 50mm f/1.8S DA DSM II Lens (Sony E)
Key Features
  • APS-C | f/1.8 to f/16
  • 75mm (Full-Frame Equivalent)
  • Ultraquiet Digital Stepping Motor
  • Nano Multilayer Coating
Improving upon its predecessor, the 50mm f/1.8S DA DSM II Lens from Yongnuo is a capable standard prime lens that's great for everyday shooting. With its upgraded digital stepping motor, this lens delivers fast and quiet autofocus performance for both photo and video. It has an antifouling fluorine coating which repels oil and water from negatively affecting the front element of the lens. Sporting a wide f/1.8 aperture and a seven-bladed diaphragm, the 50mm easily renders out-of-focus areas into beautiful and soft bokeh. Simultaneously, you'll have greater control working in low-light conditions and can operate with higher shutter speeds for sharper quality. While designed for APS-C format Sony E-mount cameras, the lens provides a 75mm full-frame equivalent.
