Nikon Camera Lens NIKKOR Z 20mm f/1.8 S [Nikon Z mount] [Nikon Z / single focal length lens]

Product Specifications

Basic Information

Product Features

A large-aperture ultra-wide-angle single focal length lens that delivers optical performance worthy of the NIKKOR Z Lens “S-Line”. With its high resolution and excellent descriptive performance regardless of shooting distance, you can enjoy a wide range of dynamic ultra-wide-angle expression, from starry landscapes to close-up subjects.

- High resolving power over the entire image regardless of shooting distance
From close-up to infinity, high resolution can be obtained consistently across the entire image range, even with the aperture wide open. Even landscapes captured wide-angle with the ultra-wide-angle 20mm lens are rendered in every corner in fine detail. Furthermore, the multi-focusing system improves the close-up AF accuracy and optical performance, and achieves the same high resolving power even at the minimum focusing distance.

- Multi-focusing system” contributes greatly to the improvement of optical performance at close range.
The multi-focus system, which precisely controls the positions of multiple focus groups with high precision by linking multiple AF drive units, improves the speed and precision of AF while also suppressing chromatic aberration at close range, where aberration is generally considered to occur, and realizes high image formation performance. The NIKKOR Z 20mm f/1.8 S contributes especially to the high optical performance at close range, achieving high resolving power that remains unchanged even at the minimum focusing distance.

- High point-image reproducibility, ideal for shooting starry landscapes
The lens effectively suppresses sagittal coma flare* at a high level from the maximum aperture, reproducing point light sources as dots even in the periphery of the image. Furthermore, the bright f/1.8 maximum aperture allows for faster shutter speeds even at low sensitivity, and beautiful pointillistic rendering of stars is possible while noise is suppressed.
(*Aberration that blurs the image of a point light source on the periphery of the image in the shape of a bird with its wings spread.)

- Smooth bokeh expression that accentuates the subject impressively
Despite being an ultra-wide-angle lens, it has been designed with smooth bokeh effect in mind to achieve beautiful bokeh expression. The lens enables impressive bokeh expressions that accentuate the sharply captured main subject in close-up photography and in photography that takes advantage of the shallow depth of field of the maximum aperture of 1.8.

- Excellent Backlight Resistance
The Nano Crystal Coating effectively reduces ghosting and flare from the sun, which tends to appear in ultra-wide-angle landscape photography. Even if there is a strong light source in the image, a clear, crisp image can be obtained. Compared to other multilayer coatings, the Nano Crystal Coating has even lower reflectance, and also provides anti-reflection over a wider range of wavelengths and angles.

- Effectively reduced axial chromatic aberration
The use of three ED lenses effectively corrects on-axis chromatic aberration from close-up to infinity. This contributes to sharp images with no color blur on the focus plane.

- Ultra-wide-angle images with minimal distortion even at the periphery
In addition to the benefits of the short flange back of the Z mount, distortion is effectively suppressed by the ideal optical design with linear symmetry across the aperture and the use of three aspherical lens elements. Despite its ultra-wide angle, the lens delivers images with minimal distortion even at the periphery of the image.

- High video performance with ease of use
Movie shooting offers the same high descriptive performance as still photography. A control ring to assign aperture, ISO sensitivity*1, and other settings allows smooth operation of focus and brightness settings, and smooth, flicker-free aperture control ensures natural changes in brightness. The AF and aperture mechanisms employing STM (stepping motors) are silent, and the control ring is clickless to minimize operation noise during movie recording.
1: For Z 7 / Z 6, it is necessary to upgrade the firmware to Ver. 2.1 or later.
2: The angle of view changes as the focus position shifts during focusing.

- Dustproof and drip-proof design
The lens barrel is designed to be dustproof and drip-proof*, with seals applied throughout the lens barrel, including moving parts, to prevent dust and water droplets from entering.
(*Dustproof and drip-proof design does not guarantee complete dustproof and drip-proof performance under all conditions.)
