When it comes to
standard primes, f/1.8 lenses are often viewed as poor relations to f/1.4 options. This Z-mount 50mm f/1.8 lens bucks the trend, with a much more sophisticated optical path than Nikon’s DSLR-based, F-mount f/1.8 primes of the past. There are 12 elements in total, including two aspherical elements, two ED (Extra-low Dispersion) elements. Both Nano Crystal Coat and Super Integrated Coating are applied to minimize ghosting and flare.
The stepping motor-based autofocus system is virtually silent yet fast for stills, while enabling smooth autofocus transitions when shooting movies. Other bonuses for movie capture are that focus breathing is practically nonexistent, and you can assign the control ring (which would normally be used for manual focusing) to stepless aperture control.
