There are no moving parts on the outside whatsoever (this is a<strong> rear focus<\/strong> lens) and it feels pretty solid while still not being particularly heavy. There is <strong>one caveat<\/strong> though: the <strong>implementation of the manual focus ring<\/strong> is not really great with most AF-S lenses, as there is some <strong>slight &#8220;slack&#8221;<\/strong> between the outer ring and the mechanics&nbsp;on&nbsp;the inside when changing the direction of rotation of the focus ring. This is a common problem that can be found in many recent Nikon AF-S lenses. As this is a 20mm wide angle lens where you rarely have to fine tune focus exactly (in contrary to a macro lens for example) this has never been a problem for me in the field, but it may be for you, so I felt like I should mention it. <strong>Turning the focus ring from infinity to 0.2 m takes roughly 45\u00b0,<\/strong> which I think is absolutely fine for a 20mm lens.<\/p>\n<p>As this is a &#8220;G&#8221; lens without an aperture ring you<strong> need an adapter that allows for aperture control<\/strong>.

Apart from that, slight coma in the corners of a fast wideangle lens is one of these things people (who often do not have taken even a single astro landscape shot) like to constantly complain about in internet forums, but which is rarely noticed in real world photos.<\/p>\n<p>In my opinion the coma performance is <strong>as good as it gets<\/strong> with a 20mm lens with a maximum aperture of f\/1.8 and <strong>this is one of my two main lenses for astro<\/strong> <strong>photography<\/strong> (alongside the Nikon 14-24mm 2.8G).

I expect <strong>better build quality<\/strong> and &#8211; because of the <strong>native E-mount<\/strong> &#8211; better handling. If I weren&#8217;t seriously into astro landscape photography I may have bought the Loxia, but as it is <strong>I perfer the 4\/3 stop advantage<\/strong> of the Nikon lens. When it comes to the optical qualities I don&#8217;t see them very much apart.<\/p>\n<p>Other<strong> fast rangefinder wide angle lenses<\/strong> would be the <strong>Voigtl\u00e4nder 21mm 1.8 Ultron<\/strong> and the very expensive <strong>Leica Summilux 21mm 1.4<\/strong>. I haven&#8217;t used either because from what I have seen I can only call their performance regarding<strong> coma wide open pretty awful<\/strong>. This does not only apply to the A7 series cameras but also to the digital Leicas, as Ron Scheffler has shown in this <a href=\"http:\/\/www.ronscheffler.com\/techtalk\/?page_id=130\" target=\"_blank\" rel=\"noopener\">blog post<\/a> (night lit scene with Leica M9 download at the bottom). Because of my shooting envelope (astro landscape) this was a very important factor to consider, YMMV. <strong>In terms of weight and also price you don&#8217;t get an advantage<\/strong> here as well.<\/p>\n<p>There are of couse a bunch of other, mostly <strong>older<\/strong> (and considerably <strong>cheaper<\/strong>) 20mm lenses, like the <a href=\"http:\/\/phillipreeve.net\/blog\/canon-fd-20mm-28-review\/\" target=\"_blank\" rel=\"noopener\">Canon FD 20mm 2.8<\/a>, the <a href=\"http:\/\/phillipreeve.net\/blog\/minolta-md-20mm-vs-canon-fd-20mm-review\/\" target=\"_blank\" rel=\"noopener\">Minolta MD 20mm 2.8<\/a> and many more but they are not as fast, the corner performance wide open is more than often nothing to write home about and same goes for the coma correction. But <strong>in case you don&#8217;t need f1.8<\/strong> in a wide angle lens, or in case you are mostly a stopped down shooter, they may be a <strong>good and cheaper alternative<\/strong> for you.<\/p>\n<h1>Conclusion<\/h1>\n<table>\n<tbody>\n<tr>\n<td><strong>good<\/strong><\/p>\n<ul>\n<li><span style=\"color: #339966;\">very good center\/midframe sharpness and contrast already at f\/1.8 at all distances<br \/>\n<\/span><\/li>\n<li><span style=\"color: #339966;\">excellent sharpness across the whole frame from f\/4.0 onwards<br \/>\n<\/span><\/li>\n<li><span style=\"color: #339966;\">bokeh<br \/>\n<\/span><\/li>\n<li><span style=\"color: #339966;\">CA correction (lateral and longitudinal)<br \/>\n<\/span><\/li>\n<li><span style=\"color: #339966;\">flare resistance<br \/>\n<\/span><\/li>\n<li><span style=\"color: #339966;\">sunstars<\/span><\/li>\n<li><span style=\"color: #339966;\">no field curvature<br \/>\n<\/span><\/li>\n<li><span style=\"color: #339966;\">coma correction<\/span><\/li>\n<\/ul>\n<\/td>\n<td><strong>average<\/strong><\/p>\n<ul>\n<li>price<\/li>\n<li>vignetting<\/li>\n<li>distortion<\/li>\n<li>build quality<\/li>\n<\/ul>\n<\/td>\n<td><strong>not good<\/strong><\/p>\n<ul>\n<li><span style=\"color: #ff0000;\">slight slack in focusing ring<br \/>\nwhen changing<br \/>\ndirection of rotation<br \/>\n<\/span><\/li>\n<\/ul>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>I had a <strong>hard time with the ratings<\/strong> above, especially where to put price and coma correction, so let me say a thing or two about these: the Nikon 20mm 1.8G is definetly <strong>not a cheap lens<\/strong>, but for what it is, and when taking into account the alternatives, the <strong>price is more than justified by the performance<\/strong> in my opinion.&nbsp; The performance regarding <strong>coma at the maximum aperture is not flawless<\/strong>, but it is also<strong> better than the average<\/strong> 20mm lens and stopping down to just f\/2.8 improves the performance dramatically, so I simply can&#8217;t fault the lens for this. The only real drawback I came across is the <strong>slight slack in the focusing ring<\/strong> when changing the direction of rotation. In case you are mainly used to manual focus lenses made of metal you may also find this lens<strong> a bit &#8220;plasticky&#8221;<\/strong>.<\/p>\n<p><strong>So, who is this lens for?<\/strong> Anyone, who looks for a <strong>lightweight, high performance wide angle lens<\/strong>, which is <strong>not as expensive as the Zeiss Loxia 21mm 2.8<\/strong>, while also being <strong>4\/3rds of a stop faster<\/strong>. Apart from convenience and build quality you are not really giving anything up here in comparison. But <strong>if you don&#8217;t need the fast aperture<\/strong> in a wide angle lens (and this may apply to many of you) there are even <strong>cheaper alternatives in the 20mm range<\/strong> (see &#8220;Alternatives&#8221; section).<\/p>\n<p><em><em>This lens can be ordered new for <strong>$750\/650\u20ac<\/strong> 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> (advertisement\/affiliate links).
