This 20mm 1.8G was wider and a lot cheaper than the <a href=\"https:\/\/phillipreeve.net\/blog\/review-nikon-af-s-24mm-1-4g-outdated-or-modern-classic\/\">Nikon AF-S 24mm 1.4G<\/a>, which was released only 4 years earlier. At that time it was one of the best options for astrophotography, as Canon had no wide angle this fast and neither did Sigma until they released their Sigma 20mm 1.4 Art in 2016. So in 2015 I already used this Nikon AF-S 20mm 1.8G to film the Aurora in Iceland with a Sony A7s, when common belief still was that it cannot be filmed in real time and one has to resort to creating timelapses to capture its movements.<\/p>\n<h2>Distortion<\/h2>\n<p><div class=\"osc-res-tab tabbable   osc-tabs-left\"><div style=\"clear:both;width: 100%;\"><ul class=\"nav osc-res-nav nav-tabs osc-tabs-left-ul\" id=\"oscitas-restabs-6-review-nikon-af-s-20mm-1-8g-64596\"><li class=\"active\"><a href=\"#ert_pane6-0\" data-toggle=\"tab\">uncorrected<\/a><\/li><li class=\"\"><a href=\"#ert_pane6-1\" data-toggle=\"tab\">corrected<\/a><\/li><\/ul><\/div><div style=\"clear:both;width: 100%;\"><ul class=\"tab-content\" id=\"oscitas-restabcontent-6-review-nikon-af-s-20mm-1-8g-64596\"><li class=\"tab-pane active\" id=\"ert_pane6-0\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-67361\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/02\/Nikon_AF-S_20mm_1.8G_2.8_Distortion.jpg\" alt=\"nikon af-s 20mm 1.8 g n ed sony 42mp 61mp a7rii a7riv a7riii a1 a9iii a7rv review resolution sharpness contrast bokeh vignetting coma z6 z7 z8 z9\" width=\"800\" height=\"533\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/02\/Nikon_AF-S_20mm_1.8G_2.8_Distortion.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/02\/Nikon_AF-S_20mm_1.8G_2.8_Distortion-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/02\/Nikon_AF-S_20mm_1.8G_2.8_Distortion-768x512.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/li><li class=\"tab-pane \" id=\"ert_pane6-1\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-67362\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/02\/Nikon_AF-S_20mm_1.8G_2.8_Distortion_corrected.jpg\" alt=\"nikon af-s 20mm 1.8 g n ed sony 42mp 61mp a7rii a7riv a7riii a1 a9iii a7rv review resolution sharpness contrast bokeh vignetting coma z6 z7 z8 z9\" width=\"800\" height=\"533\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/02\/Nikon_AF-S_20mm_1.8G_2.8_Distortion_corrected.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/02\/Nikon_AF-S_20mm_1.8G_2.8_Distortion_corrected-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/02\/Nikon_AF-S_20mm_1.8G_2.8_Distortion_corrected-768x512.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/li><\/ul><\/div><\/div><span style=\"color: #999999;\"><em>Nikon Zf | Nikon AF-S 20mm 1.8G | f\/2.8<\/em><\/span><\/p>\n<p>This Nikon AF-S 20mm 1.8G shows a low amount of barrel distortion.

The latest designs like the <a href=\"https:\/\/phillipreeve.net\/blog\/review-nikon-z-20mm-f-1-8-s\/\">Nikon Z 20mm 1.8 S<\/a> or the <a href=\"https:\/\/phillipreeve.net\/blog\/review-sony-fe-20mm-1-8g\/\">Sony FE 20mm 1.8 G<\/a> are generally better corrected lenses. For that better correction they are also about double as expensive though and it is questionable if you will really notice that optical difference in the field &#8211; unless you do a lot of astrophotography, there you probably will.<\/p>\n<p>Mind you, some corners have also been cut when it comes to the build quality. Mostly plastic (also on the inside) and the slack in the focus ring is not something I am fond of either.<\/p>\n<p>This lens still ticks many boxes though: flare resistance is very good, stopped down sharpness is very good, bokeh is nice, sunstars are nice and on the used market this lens is pretty affordable now. So if you are looking for an affordable lens in this range for your Z camera with FTZ adapter &#8211; or for a late analogue F-mount AF SLR &#8211; this can still be a good choice.<\/p>\n<p><em>This lens can be ordered new for <\/em><em><strong>$750<\/strong>&nbsp;on <a href=\"http:\/\/www.amazon.com\/gp\/product\/B00NI6WH1S\/ref=as_li_tl?ie=UTF8&amp;camp=1789&amp;creative=9325&amp;creativeASIN=B00NI6WH1S&amp;linkCode=as2&amp;tag=httpphillinet-20&amp;linkId=UK4DSQZVVEBN3ZD4\">Amazon.com<\/a><img loading=\"lazy\" decoding=\"async\" style=\"border: none !important; margin: 0px !important;\" src=\"http:\/\/ir-na.amazon-adsystem.com\/e\/ir?t=httpphillinet-20&amp;l=as2&amp;o=1&amp;a=B00NI6WH1S\" alt=\"\" width=\"1\" height=\"1\" border=\"0\">\/<a href=\"http:\/\/www.amazon.de\/gp\/product\/B00NI6WH1S\/ref=as_li_tl?ie=UTF8&amp;camp=1638&amp;creative=6742&amp;creativeASIN=B00NI6WH1S&amp;linkCode=as2&amp;tag=httpphillinet-21\" rel=\"nofollow\">Amazon.de<\/a>\/<a href=\"https:\/\/bhpho.to\/2JIoFZv\">B&amp;H<\/a> you can also find used ones on <a href=\"https:\/\/www.ebay.com\/sch\/i.html?LH_CAds=&amp;_ex_kw=&amp;_fpos=&amp;_fspt=1&amp;_mPrRngCbx=1&amp;_nkw=nikon+20mm+1.8&amp;_sacat=625&amp;_sadis=&amp;_sop=12&amp;_udhi=&amp;_udlo=&amp;_fosrp=1&amp;mkrid=711-53200-19255-0&amp;siteid=0&amp;mkcid=1&amp;campid=5337820130&amp;toolid=10001&amp;customid=&amp;mkevt=1\">ebay.com<\/a>\/<a href=\"https:\/\/www.ebay.de\/sch\/i.html?_ex_kw=&amp;_mPrRngCbx=1&amp;_nkw=nikon+20mm+1.8&amp;_sacat=625&amp;_sop=12&amp;_udhi=&amp;_udlo=&amp;_fosrp=1&amp;mkrid=707-53477-19255-0&amp;siteid=77&amp;mkcid=1&amp;campid=5337820130&amp;toolid=10001&amp;customid=&amp;mkevt=1\">ebay.de<\/a> starting at <strong>$400<\/strong> (advertisement\/affiliate links).<\/em><\/p>\n<p><strong>A word of caution:<\/strong> I was looking for a Nikon AF-S 20mm 1.8G to use on my Nikon Zf and analogue Nikon F80 in 2025. I tried three different samples. All of them showed a slight decentering in the midframe, while the decentering test in the corners looked okay (this can happen with fast wide angle lenses). On all three of them the MA\/M switch did not work at first. On two of them moving it back and forth a few times got it to work again, on the third it was simply broken. Two of them also had radial play between the front and the rear part of the lens, which luckily can be fixed rather easily, if you are familiar with opening and working on lenses. I can only recommend buying this lens used when you have the chance to check it out in person before buying or if you can easily return it.<\/p>\n<h2>Alternatives<\/h2>\n<p>Many alternatives are covered in our <a href=\"https:\/\/phillipreeve.net\/blog\/wideangle-lenses-for-the-sony-alpha-7-series\/\">Guide to 20-28mm wide angle lenses<\/a> for E-mount, so I will only talk about the most obvious ones in detail here.<\/p>\n<h3>Z-mount<\/h3>\n<p><a href=\"https:\/\/phillipreeve.net\/blog\/review-nikon-z-20mm-f-1-8-s\/\"><em><strong>Nikon Z 20mm 1.8 S<\/strong><\/em><\/a><br \/>\nFor the Z-mount users this is kind of the obvious choice.
