The Nikon NIKKOR Z 50mm f/1.2 S is a fast, normal-length prime featuring advanced optics and a bright design to suit everything from available-light portraiture to selective-focus documentary subjects. A series of extra-low dispersion and aspherical elements also help to achieve high sharpness, notable clarity, and accurate rendering while ARNEO and Nano Crystal Coats, as well as a Super Integrated Coating, suppress flare, ghosting, and surface reflections for improved contrast and color fidelity. The lens also has a unique physical design, which incorporates a top OLED information panel that can be used to quickly confirm aperture and focus settings, and an assignable L. Fn button permits making exposure and settings adjustments via the lens. Impressively bright f/1.2 maximum aperture excels in low lighting conditions and also offers extensive control over depth of field for working with selective focus techniques. Two extra-low dispersion elements greatly reduce color fringing and chromatic aberrations in order to produce greater clarity and color rendering. The Nano Crystal Coat controls incidental light from a diagonal direction while the ARNEO Coat controls incidental light from a vertical direction. Super Integrated Coating is also featured on multiple elements to help ensure consistently accurate colors. This system uses stepping motors, which offer impressively smooth and quiet autofocus performance that is well-suited to both stills and video applications. Programmable Control Ring is, by default, set to adjust manual focus, but can also be used to control aperture or exposure compensation. The Assignable L. Fn button works in conjunction with camera-based Fn buttons to provide a seamless point for quickly changing exposure settings and other functions. The rounded nine-blade diaphragm promotes a pleasing out-of-focus quality that benefits the use of shallow depth of field and selective focus techniques.
