Product Description

Nikon NIKKOR Z 20mm f1.8 S Lens

An ultra-wide field of view along with a sleek form factor, the NIKKOR Z 20mm f1.8 S from Nikon is a versatile prime well-suited to a range of subject types, from architecture to interiors to landscapes. An advanced optical design uses aspherical and ED elements to produce sharp, well-corrected imagery with high clarity and colour accuracy, and both Nano Crystal and Super Integrated Coatings are also used to suppress flare and ghosting for greater colour fidelity and higher contrast.



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. Additionally, a programmable control ring can be set for intuitive adjustment over a variety of camera and exposure settings.

Prime wide-angle lens is designed for FX-format Z-mount mirrorless cameras, however, can also be used with DX models where it provides a 30mm equivalent focal length.



Bright f1.8 maximum aperture suits working in difficult lighting conditions and also offers increased control over the depth of field.

Three aspherical elements are used to reduce spherical aberrations and distortion in order to realize sharp imagery with accurate rendering.

Three extra-low dispersion elements greatly reduce colour fringing and chromatic aberrations throughout the zoom range in order to produce greater clarity and colour rendering.

A Nano Crystal Coat, along with a Super Integrated Coating, has been applied to lens elements to minimize surface and internal reflections for a marked reduction in lens flare and ghosting.



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 qualities, that are 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.



A specialized electromagnetic aperture mechanism provides greater exposure control stability which 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. With its dust- and moisture-resistant design, this lens is built to withstand inclement conditions, keeping your photos sharp and clear no matter what the weather is like.

Understanding: Aperture

Aperture is the opening in a camera lens that controls how much light enters the camera. It's measured in f-stops like f/2.8 or f/8. Lower f-stop numbers mean wider openings, letting in more light and creating a shallow depth of field (blurry background). Higher f-stop numbers mean smaller openings, letting in less light and creating a larger depth of field (more of the scene in focus). Aperture also affects the quality of out-of-focus areas in the image (bokeh).

Understanding: Lens Types

Different lenses have different purposes to achieve different styles of images, some popular ones include:
Prime Lens: Fixed focal length, sharp images, great for portraits and dark settings.
Zoom Lens: Variable focal length, versatile for different shots and everyday use..
Wide-Angle Lens: Captures wide scenes like landscapes.
Telephoto Lens: Magnifies distant subjects, ideal for sports & wildlife.
Macro Lens: Perfect for close-up photography of small subjects.
Fisheye Lens: Ultra-wide perspective, creates unique images.

Understanding: Lens Mounts

Different camera brands use different lens mounts, which are like connectors that attach lenses to camera bodies. Each mount is specific to a particular brand and camera series. For example, Canon uses the EF and RF mounts, Nikon uses the F mount, Sony uses the E mount for its mirrorless cameras. These mounts dictate which lenses are compatible with which cameras. Some brands offer adapters to use lenses from other systems, but it's essential to ensure compatibility for proper functionality and autofocus performance.

Understanding: Manual and Autofocus

Manual focus and autofocus are two ways to adjust the sharpness of a camera lens. With manual focus, you turn a ring on the lens to bring the subject into focus yourself, giving you full control over what appears sharp in the image. Autofocus, on the other hand, relies on the camera's built-in technology to automatically adjust the focus for you, usually by detecting contrast or phase differences in the scene. Autofocus can be convenient, especially for fast-moving subjects or when you need to capture a quick shot, whereas manual focus allows for precise adjustments and creative control over the final image.
