Built for speed and exacting sharpness, Nikon's 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. The f/1.2 maximum aperture excels in difficult lighting conditions and offers impressive control over depth of field to help isolate subject matter against a blurred background. 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.
Complementing the optical design, a multi-focus system, which employs two stepping motors, helps to realize impressively fast, accurate, and quiet focus performance, along with full-time manual focus override, to suit both stills and video needs. 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. Additionally, a programmable control ring can be set for intuitive adjustment over a variety of camera and exposure settings.
- Bright normal-length prime is designed for FX-format Z-mount mirrorless cameras, but can also be used with DX models where it provides a 75mm equivalent focal length.
- 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.
- Three aspherical elements are used to reduce spherical aberrations and distortion in order to realize sharp imagery with accurate rendering.
- Two extra-low dispersion elements greatly reduce color fringing and chromatic aberrations in order to produce greater clarity and color rendering.
- ARNEO and Nano Crystal Coats are used to prevent ghosting, reflections, and flare in order to realize improved contrast and clarity when working in strong lighting and backlit conditions. The Nano Crystal Coat controls incidental light from a diagonal direction while the ARNEO Coat controls incidental light from a vertical direction. A Super Integrated Coating is also featured on multiple elements to help ensure consistently accurate colors.
- Multi-focus system incorporates two separate AF drive units, which are synchronized, to deliver especially fast and accurate focusing performance. This system uses stepping motors, which offer impressively smooth and quiet autofocus performance that is well-suited to both stills and video applications. Full-time manual focus override is also possible and an internal focusing design is used, where only the internal lens groups are moved during focusing, to maintain the overall length of the lens during use and to promote faster focusing speeds.
- Programmable Control Ring is, by default, set to adjust manual focus, but can also be used to control aperture or exposure compensation.
- Integrated OLED lens information panel allows you to quickly confirm aperture setting, focus distance, and depth of field figures right on the lens in both bright and dark situations.
- 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.
- Specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates.
- Rounded nine-blade diaphragm promotes a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
- Dust- and moisture-resistant lens barrel benefits the lens' use in inclement conditions.
