Nikon 20mm f/1.8 overview

  • 1Description

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 has 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 20mm f/1.8 reviews

    AF-S NIKKOR 20mm f/1.8G ED Lens is rated 4.8 out of 5 by 167.
    Rated 4 out of 5 by from A good prime lens I bought this lens for use on my new D750. I am an amateur landscape photographer, and wanted to be able to capture some nightscapes along with my more typical dusk/dawn work. Overall, I really like this lens. It's sharp and the contrast is great. I do see some vignetting, but not a lot. It focuses fast and quietly. I'm not an expert by any means, so I can't provide much more detail than that. I have used it during three different outings - one daytime, once at night and once for a weekend that included a few different times of day. The only thing I haven't played with yet (surprisingly) is the bokeh, so I can't speak to that.

    Rated 5 out of 5 by from performs better than I expected As a wedding photographer I use this lens mainly for bride-groom accessories and close quarter large group photos. For the group photos the distortion is acceptable and sharpness top notch. When shooting the couples accessories the short focal distance gives a great wide macro type perspective. Bokeh is very nice and sharpness is excellent. What I really like to shoot with this lens are landsapes. Its low light capability gives great exposures for night scenes and the starburst effect is just marvelous. Day photos are sharp and clean but works best from f5.6 and up.

    Rated 5 out of 5 by from Exceeded All Expectations Incredibly sharp across the frame and super-quick to focus. I can't praise this lens enough. Lightweight, sharp, and distortion-free. Not much else to ask for! Nikon has another winner here and I look forward to more time and more photo opportunities with this lens. Don't let the Made in China label prevent you from adding this gem to your collection. While it may FEEL cheap in the hand compared with some of the pro glass out there at 3X the price, there is nothing cheap about the images this lens is capable of capturing. Go out and buy one-you will not regret the decision.

    Rated 5 out of 5 by from Top Performer Before purchasing this lens for landscape photography with my d610, I considered a few other options including Nikon 14-24, Nikon 18-35 and Nikon 16-35. The 14-24 and 16-35 are much more expensive, and the 18-35 is priced similarly as the 20mm. I went with this lens for a few different reasons. First it is very sharp. Sharpest lens I have owned, in the center and corners, and I can see how others have said that it matches or beats the sharpness of the 14-24mm which is one of the best landscape lenses made. The distortion is almost non-existent. As is vignetting. This lens is also very lightweight, yet still has solid construction. Overall this is a great quality lens and beats everything else in its class and price range.

    Rated 5 out of 5 by from No Barrel Distortion If you need an ultra wide and wince at barrel distortion, this is the lens for you. And it has both ED and Nano elements - don't listen to criticisms that the N coating is mostly for marketing purposes - the N coated Nikon lenses always have superior contrast to those without it. The two pointless images that follow illustrate the lack of barrel distortion (yes, there's distortion with any wide angle shot by definition - but this photo is intended to see what happens when you line up the frame edge to a straight line - in this case the left side of the door). Top photo is uncorrected; bottom photo is corrected in CS6 RAW profile auto correct. ISO 100, 1/100th hand held at f3.2. D4s.

    Rated 5 out of 5 by from Very Satisfied So far I have used it for a few architectural shoots (both interior and exterior)...and so far I'm impressed and happy I decided to buy it. Autofocus is quick, accurate, and quiet. I've also focused manually in live view...the focus ring is of typical Nikon quality...precise and easy to turn. Images are crisp and clear. I have not noticed any aberration when used wide open at f/1.8, with very slight vignetting (easily correctible in post). Vignetting seems to be gone at f/2.8. Extremely minor distortion at corners typical of a lens in this focal range. For those of you who will be using this lens for outdoor landscape shoots at f/8 or f/11, this lens really shines at those and contrasty from center to edge, much like the Zeiss 21mm f/2.8 Distagon. The lens relatively light, compact, and easy to carry around.

    Rated 5 out of 5 by from replaced my 16-35 I have the Nikon 16-35 f/4 and bought this 20mm as a likely replacement it has a reputation for being sharper and having less distortion. (I have a 24-70 also, so there was a lot of overlap in the range with the 16-35 that I didn't need to be duplicating). Comparing the two, I am loving this as it is smaller, lighter, has much less distortion, I do think sharper, and does just what I want. I have not had it out for night photography yet, but its speed will no doubt be appreciated over the 16-35 as well. I will be selling the 16-35 and just using this one.

    Rated 5 out of 5 by from Great Lens for That Extra Field of View I've had this lens for a few months and it delivers an extra wideness for my shots that I was looking for. My reasoning behind getting the 20mm is experience with a 24mm setting on the workhorse 24-120mm zoom. I felt I needed just a tad more field of view, yet not something too extreme. I do look at MTF charts, etc. for lenses to get a feel of CA and sharpness, but cost is a big factor, of course. With this lens you can nail a great photograph. I've found its autofocus to be quick and accurate on my D750, from closeups to infinity. The results are best seen in a picture. I've uploaded a shot of the George Washington bridge from the park to its north. I wanted to get the stone and brick walkway in the foreground and the entire bridge. It's a very useful lens to have in your camera bag. Specs on the image: Nikon D750, 1/125 @ f/14, ISO 100
