Nikon Z System. The Nikon Z 20mm f/1.8 S was designed specifically for cameras in Nikon’s new full-frame Z-mount system. Z-mount lenses only work with Z-mount cameras, and Z-mount cameras are only compatible with Z-mount lenses.

Wide-Angle Prime. The 20mm focal length is a popular choice for a range of subjects. It’s often used for portraiture, street photography, and reportage.

High-Quality Optics. The Nikon 20mm f/1.8’s eleven-group/fourteen-element optical design features three extra-low dispersion elements and three aspherical elements to promote sharpness and color rendering while limiting chromatic aberrations. Nikon has applied Nano Crystal and Super Integrated coatings to the elements to combat ghosting and lens flare, even when you’re working in bright or backlit conditions.

Fast Aperture. The f/1.8 aperture allows an exceptional degree of subject/background isolation that makes it ideal for portraiture. It also enables the lens to be very useful for low-light shooting. The nine rounded aperture blades contribute to smooth bokeh.

Multi-Focus Autofocus System. This lens’s multi-focus system incorporates two synchronized autofocus drive units to give you fast, accurate performance. This system’s stepping motors provide smooth, nearly silent performance that’s particularly suited to video applications. You also get full-time manual focusing for precision adjustments, while the internal-focusing design means that the lens maintains its length during focusing.

Durable Build. This lens’s durable, moisture-resistant construction means you can use it in adverse conditions without worry. The exposed elements have a fluorine coating to protect them from debris and smearing. A programmable control ring lets you adjust manual focus, aperture, or exposure compensation.
