In short

Nikon 20 / 1.8G is a fast ultra-wide angle lens for Nikon full-frame DSLR cameras, can be easily used on mirrorless cameras of the system Nikon Z using a special adapter Nikon FTZ.

Nikon 20 / 1.8G has a very high, as for a similar lens, aperture... Lenses with a focal length of 20 mm for a full frame and aperture F / 2 / 1.8 / 1.4 are extremely rare.

Nikon 20 / 1.8G is a very serious update from the outdated Nikon AF Nikkor 20mm 1: 2.8D.

Nikon 20 / 1.8G belongs to professional solutions. The Nikon 20 / 1.8G has few obvious drawbacks. Nikon 20 / 1.8G turned out to be very successful and deserves due attention.

History

Nikon 20 / 1.8G was presented 12 September 2014 year and became a replacement for the older Nikon AF Nikkor 20mm 1: 2.8D, presented back in March 1994. At the same time Nikon AF Nikkor 20mm 1: 2.8D is an almost complete copy of the older Nikon AF Nikkor 20mm 1: 2.8 [NON-D], introduced back in 1989.

You can also assume that the Nikon 20 / 1.8G actually belongs to a radically new line of lenses that have significantly improved their performance over their predecessors.

Assembly

The Nikon 20 / 1.8G is pleasant to the touch. The lens body is made of plastic, the Nikon 20 / 1.8G weighs only 350 grams. But the light weight and plastic body sometimes gives the feeling of an inexpensive solution. In addition, if you shake the lens slightly, you can clearly hear how something dangles inside... This is the norm and is not a breakdown.

The focusing ring is very wide and rubberized. Nikon 20 / 1.8G uses metal mountnear which is located rubber compressorthat protects the camera mount from dust and moisture. Nikon 20 / 1.8G is made in China only.

There is a bayonet mount mark on the body and a mark for quick installation of the hood. The lens uses a small plastic hood HB-72, which is fixed in special grooves located near the front lens of the lens. A hood is included with the lens. The hood can be installed in the opposite direction for transportation. In this position, access to the focusing ring is partially lost.

Nikon 20 / 1.8G comes in a small cardboard box with characteristic Nikon coloring. The lens is held in the box using a special plastic box-holder.

Diaphragm lens consists of 7 rounded petalswhich form a fairly flat opening at all apertures.

Nikon 20 / 1.8G belongs to professional lenses. As befits a professional lens - the diameter of the front filter is the classic 77 mm.

Focusing

Nikon 20 / 1.8G focuses thanks to 'SWM'-motor (Silent Wbird Motor is a quiet wave / ultrasonic focus motor) and refers to 'type lensesAF-S'(with built-in motor focusing), and therefore it will automatically focus on any Nikon digital SLR camera. The lens is used compact swm motor.

The lens will automatically focus on all Nikon DSLR cameraseven on amateur series models Nikon DXthat do not have a built-in focus motor: D40, D40x, D60, D3000, D3100, D3200, D3300, D3400, D3500, D5000, D5100, D5200, D5300, D5500, D5600as well as mirrorless cameras Nikon Z using the FTZ adapter.

During auto focus, the motor does its job quietly enough, but still noise from the focus motor is clearly audible in videos recorded using the camera's built-in microphone.

Auto Focus Speed ​​- high... The running time of lenses from infinity to MDF and back is short.

There are no special problems with focusing, but on my cameras I noticed rare focusing errors, there are few of them, but they still make themselves felt. I associate them with the difficulty of focusing on an ultra-wide angle lens with high aperture... But overall, the lens focuses quickly and confidently.

The front lens remains stationary during focusing. The lens uses focusing type RF (Rear Focusing), which is done by moving the rear lens group. For practical use, the RF type focusing is no different from the IF ('Internal Focus' - 'Inner Focus'). With this lens, you can easily use any filters, for example, polarizing.

The minimum focusing distance is only 20 cm, while you can shoot with a maximum magnification of 1: 4.35... This is an excellent indicator for a lens like this. An ultra-wide angle of view paired with a small MDF helps to create photos with an interesting wide perspective effect.

During auto focus, the focus ring remains stationary. In manual focus mode, the ring rotates approximately 90 degrees, when the extreme positions are reached, it does not rest, but continues to slide, without affecting the focusing. It is quite difficult to focus manually.

On the lens housing you can find focus switch 'M / A - M'. In the 'M / A' position, auto focus works with constant manual focus priority. The 'M / A' mode is very convenient and useful - for manual focusing or focus correction, you do not need to additionally switch the lens to the 'M' mode.

Focus Features:

  1. There is a depth of field scale, but only for F / 16
  2. There is a fairly strong 'Focus Breathing' effect (changes in the angle of view during focusing). When focusing towards MDF, the angle of view decreases
  3. The lens has a scale with a focusing distance in meters and feet in the form of a window. There are values ​​only for the infinity mark, 0.4, 0.25, 0.2 meters. In fact, this scale is useless.
  4. The Nikon 20 / 1.8G does not have a hard infinity mechanical stop for fast and accurate infinity aiming under any operating temperature.
  5. Focus Shift (shift focus, changing the focus distance due to iris) is missing.
  6. The lens must be well compatible with the Nikon FTZ adapter for Nikon Z mirrorless cameras and with a Nikon FT1 adapter for cameras Nikon 1
  7. When used on cameras Nikon D3200, D40, D700, the green dot confirming correct focusing is working correctly.

Image quality

The lens was developed at a time when there were already 36 MP Full Frame cameras and APS-C cameras with a 24 MP sensor, and therefore the Nikon 20 / 1.8G should not have any problems with modern high pixel density sensors.

The lens frankly surprised at 24 APS-C sensor Nikon D3200 (CMOS, 24 MP), where already at F / 1.8 in the center of the frame it created a very sharp image. On camera Nikon D700 with a low pixel density Nikon 20 / 1.8G is simply gorgeous in terms of sharpness.

Sharpness

  • confident sharpness at the open aperture in the center of the frame
  • very high resolution at f / 2.8-f / 8
  • there is a drop in sharpness in the corners of the frame at F / 1.8, when closing to F / 2.8, sharpness returns to normal

Distortion

  • small distortion
  • the overall level of distortion is at a level typical for such high-quality lenses
  • the nature of the distortion is unified - the usual barrel-shaped distortion, can be easily corrected in the editor

Vignetting

  • the overall level of vignetting is at a level typical for such lenses
  • vignetting is strongest when focusing to infinity at open apertures
  • vignetting is easily fixable in the editor
  • vignetting is almost unchanged using two light filters, I tried Hoya Pro1 Digital 77mm MC UV (0) made in Japan + cheap Citiwide CPL 77mm

Aberration

  • lens suffers from chromatic aberrations
  • strong frigging (example)
  • strong blooming (example)

Rest

  • in the backlight, you can get large glare (Example 1, Example 2), but if you choose the right angle, then this can be avoided. Even if the lens catches glare, the overall contrast is high.
  • getting the effect of a 14-ray star is quite simple (example)
  • sometimes you can get neutral and even pleasant bokeh
  • the disks of confusion have concentric 'onion' circles from aspherical optical elements

Modern Nikon cameras, which were released after the announcement of this lens, easily automatically correct distortion and vignetting. Many cameras are able to automatically correct some of the chromatic aberrations. Sometimes software features that enhance the original lens image can work wonders.

If a camera that was released before 2014 is used with this lens, then shooting in RAW with the further use of the latest version of Capture NX-D or any other original modern utility allows you to automatically correct vignetting, distortion, and chromatic aberration.

My experience

I worked with Nikon 20 / 1.8G for about two weeks and shot several events with it, I was very pleased with the final image.

I really liked Nikon 20 / 1.8G. Nice and very functional lens. True, while working with Nikon 20 / 1.8G one gets the impression that you are working with a budget Nikon 35mm f / 1.8G DX... This is due to the plastic light body, in the middle of which something dangles and the compact focusing motor, which emits its characteristic sound during operation.

Nikon 20 / 1.8G is very good at crop, where it converts to a stock standard lens. 24 megapixels on the APS-C sensor is not a hindrance for him, even at F / 1.8.

Nikon 20 / 1.8G is one of the sharpest lenses I've ever shot.

I recently reviewed a similar manual premium lens. Carl Zeiss Distagon 2.8 / 21 T * ZF.2which is better than Nikon 20 / 1.8G in the image corners. Still, I think the Nikon 20 / 1.8G is a much more balanced solution.

Nikon 20 / 1.8G can be safely bought and used for its intended purpose.

  • notapic

    Everywhere it is written Nanon instead of Nano, in "History" it would be more appropriate to write not increased characteristics, but improved. And before the start of the photo from the D700 it says "vignetting", you need to fix

    • Arkady Shapoval

      Fixed (crop watermark in the photo with the lens view)

    • Nanon

      Smart you are just outrageous. Another would not even pay attention and quietly walked by ... Perhaps you work as a Russian language teacher? Or just a bore ???

      • Arkady Shapoval

        It's not very difficult for me to fix it. Find more - write.

        • alex

          “Is almost a complete copy of the more strictly Nikon AF Nikkor 20mm 1: 2.8 [NON-D]” - I think it should be “old” instead of “strict”.
          To Nanon.
          Someone doesn’t give a damn about what kind of poyardke bkuvy are most dangerous, but someone the slightest mistake cuts the eye, makes you stop, think, interferes with calm reading. This article is public information, and therefore, it seems to me, should comply with the rules of the language in which it is written. It is not only dry information that is important, but also how it is presented. Among other things, it depends on the correct spelling. In general, there are many reasons to write correctly. Nobody blames the author, people just point to typos.

          • Arkady Shapoval

            Fixed

        • Ivan

          “Not difficult” is written together.

          • Arkady Shapoval

            Fixed

  • notapic

    In general, the lens seems to be not bad, I'm thinking of taking it as a full-frame width. Or are there more balanced solutions like 14mm fixes or some kind of wide-angle zoom?

    • Arkady Shapoval

      14 mm is a different heaven.
      The native 16-35 / 4 is praised, as is the native 14-24 / 2.8. It depends on what exactly is needed, that should be looked at.

  • Dmitriy

    One of the options for using this lens is for shooting night landscapes (the aperture allows), for which one of the most important criteria is the absence of a serious coma near open apertures. Unfortunately, I did not find information about this parameter in the review.

    • Arkady Shapoval

      I add: coma in the full frame in the far corners is significant at F / 1.8, noticeably reduced at F / 2.8 and beyond.

      • Dmitriy

        Thank you!

  • koba

    “The lens has a scale with a focusing distance in meters and feet in the form of a window. There are values ​​only for the infinity mark, 0.4, 0.25, 0.2 meters. In fact, this scale is useless ”- here it is. So it is with another optically superior lens - 24 / 1.8G. Because of the autofocus speed, the rotation distance was reduced to almost zero, I wonder how to work with this lens in manual mode now? And the good news is that you can work in manual mode, use zone focus, hyperfocal ... For me personally, this lens, like its new ones, are completely useless, since in 99% of cases I work in manual mode at 24mm. A pity, a pity! The last lens suitable in this respect Nikon made 24 / 2.8 Ai, but soon, in the Ai-s version, “corrected” the situation and never again set 3 meters markings on the distance scale, without which they turn into toys of little use. Interestingly, in the company of Nikon at least once you saw the shirikas from Lake?

    • R-nOleg

      Good lens. Bokeh interesting as for shirik

      • koba

        In my opinion, this is just an excellent lens, and also lightweight, etc. Those who work only with autofocus are just a godsend for them. We would have made him a distance scale with a mark of 3 meters, he would have bought it himself today.

    • Victor

      So, my gut tells me that manufacturers have long ago “hammered” the distance scale and the markings there are conditional. Problem 3 meters, COBA is not a problem, you can mark it yourself on your lens. What's in the way? And, here, the reduction of the general distance scale for the sake of autofocus is, forgive me for the non-literary syllable, CRASH! Especially for those for whom manual focus is important! Here, I completely agree with COBOY.

  • Michael K.

    The D40 has a nice, calm soft picture.

  • Victor

    On d40 the picture is nicer than on d3200, and on the “outdated” 2.8D the picture is nicer than on the new, all-better 1.8G Sad but true.

  • Romance

    The question about focusing is open, is it aiming at infinity if you turn it all the way to (stop)? Or jumps? Interested in stars and northern lights. Lack of night photos in the review, what the lights of the night city look like 😁
    Are there owners of Tamroshi 15-30?

    • Arkady Shapoval

      In the sense of open, I pointed out in the review: Nikon 20 / 1.8G does not have a hard stop (hard infinity mechanical stop) for fast and accurate aiming at infinity under any temperature operating conditions.

  • july

    Probably a really good lens) Beginner amateur, it's a pity to buy a new one, at the moment there is not a single valid proposal for Russia on Avito.

    • Boris

      Yes, on the secondary housing this is rare, much less often than 14-24, for example. When I bought my own, no one put it up for sale either. I had to search on the Polish OLX website and ask my friends to buy it there. The Polish seller agreed to shoot test footage, so he saw that I was buying. Now I constantly shoot 35 along with 85 and 1,8, all from the XNUMXG series. And most importantly, I bought a third cheaper than a new one!
