Nikon AF-S NIKKOR 20mm f/1.8G ED Overview

By B&H Photo's

A smart ultra-wide, the AF-S NIKKOR 20mm f/1.8G ED from Nikon blends a desirable broad field of view with a sleek form factor, a bright design, and a sophisticated optical layout. The fast f/1.8 maximum aperture excels in difficult lighting conditions and also offers increased control over depth of field. The optical design incorporates both aspherical and extra-low dispersion element to minimize spherical and chromatic aberrations for greater sharpness and clarity. Also, both Nano Crystal and Super Integrated Coatings have been applied to reduce flare and ghosting for improved contrast and color accuracy. Balancing the optical attributes, the lens is also characterized by a Silent Wave Motor that produces fast, smooth, and quiet autofocus capabilities, along with the ability to manually override focus at any time for more selective control.

Ultra wide-angle prime is designed for FX-format Nikon F-mount cameras, however can also be used with DX models where it provides a 30mm equivalent focal length.
Bright f/1.8 maximum aperture benefits working in low-light conditions.
Two extra-low dispersion glass elements are used in the optical construction to reduce a variety of chromatic aberrations and color fringing for a high degree of clarity and color neutrality.
Two aspherical elements are featured to control spherical aberrations and distortion in order to produce notable sharpness and resolution.
Nano Crystal and Super Integrated coatings have been applied to lens elements to minimize surface and internal reflections for a marked reduction in lens flare and ghosting.
Silent Wave Motor affords quick, quiet, and precise autofocus performance along with full-time manual focus override. A rear focusing design is also used, where only the rear lens group is moved during focusing, to maintain the overall length of the lens during use and to promote faster focusing speeds.

Nikon AF-S NIKKOR 20mm f/1.8G ED Reviews

In the past 8 years I've gone through three, yes, three 17-35mm Nikon lenses. And they're not cheap either. I was so disappointed when my third 17-35mm stopped working a few weeks ago, that I decided to go completely with prime lenses, so I picked up this 20mm lens. I've never had issues with Nikon's prime lenses and this 20mm has all the main reasons why I love them: such as corner to corner sharpness, lightweight and beautiful bokeh at f 1.8---As a news photographer I wish I had the convenience of 17-35, but I'm completely done with blurry edges and malfunctioning zoom functions during assignments.

Today is day-one with this lens and I had posted earlier, a photo from my balcony of the Chase building and a nearby church. I am posting the same area by night with this lens. Hand -held, untouched by any photo editor software and straight out of the camera.

My first photo with this lens

I got the lens today, attached it to my D750 and took this picture, all in five minutes! Did minimal post-processing in Light room Classic, mainly to straighten the building and I couldn't be more pleased. The lines look sharp and the colors are vibrant. I have always used my 24 to 120 zoom previously and had heard bout how much better the prime lenses are. I completely agree. It is small and light weight, but a heavy weight in performance in it's class. Will post more pictures as I get to use the lens more, but my initial take on the lens can't be any better.

Great Pics

I'm thoroughly impressed with how sharp this lens is. The lens is very responsive I'm AFRAID. I had heard but seeing is believing.

This lens is fast, sharp, has impressively close minimum focus distance, and fast accurate autofocus. Quality wide perspective with minimal distortion. I can't say enough about how much I love this lens.

It's a wide world.

This review cannot do any better on technical issues than those that came before on this site. Images are crisp and the lens doesn't disappoint. It offers abundant conformance quality. I guess my strong offer of an opinion is to order one from B&H. Yes, the price is good, but the execution of the order is compelling. I live in a remote area for delivery, but they get an order going so fast that it arrives sooner than any other company that i use for consumer stuff. Super fast, and everything just as it should be. Not my first one from here, and I'll be back.
