Yongnuo 50mm f/1.8S DF 50mm
A bright f/1.8 full-frame lens for Sony E-mount, this 272g prime uses an ultra-quiet DSM stepping motor for smooth, silent autofocus. A customizable function button and USB-C firmware port add practical versatility, while the 9-blade diaphragm produces smoothly blurred backgrounds.
