The NIKKOR Z 24-70mm f/2.8 S from Nikon is a workhorse standard zoom, covering wide-angle to portrait-length fields of view. Characterized by its bright f/2.8 constant maximum aperture, this lens is suitable for working in a variety of lighting conditions and also offers increased control over the depth of field for isolating subjects and working with selective focus. Additionally, ARNEO and Nano Crystal Coats, as well as Super Integrated Coating, have been applied to 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. Constant f/2.8 maximum aperture offers consistent performance throughout the zoom range and also benefits working in difficult lighting conditions and using selective focus techniques.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. Super Integrated Coating is also featured on multiple elements to help ensure consistently accurate colors. 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.
