Yongnuo has officially introduced a new autofocus lens for mirrorless cameras of the Nikon Z system. This lens is the YN50mm F1.8 Z DF DSM model.
The optical design of the Nikon Z lens and its characteristics are completely identical to the E-mount version of the YN50mm F1.8S DF DSM lens for Sony cameras.
The new lens uses an optical structure consisting of 11 lenses in 8 groups and a nano-multilayer coating. According to the manufacturer, this coating can effectively increase light transmission and suppress ghosting and backlight glare. It also reported that a single aspherical lens effectively compensates for a variety of aberrations, and a single low dispersion glass element can solve the dispersion problem.
The YN50mm F1.8 Z DF DSM lens is equipped with digital stepper motor (DSM) autofocus. According to the manufacturer, this focus motor has a fast start and stop, high accuracy, and noiselessness, which makes it universal for both photos and videos.
