Naturally the performance is much better stopped down. If you occasionally want to use the lens at closer distances a good diopter like e.g. the Leica Elpro4 will give better results.<\/p>\n<h2>Flare resistance<\/h2>\n<figure id=\"attachment_2244\"

So even by today&#8217;s standards it is still a solid, capable performer with high contrast at maximum aperture, decent CA correction and surprisingly low coma in a very compact and well made package.<br \/>\nMy sample is from 1987 and it still looks and works like new, which is a testament to the high mechanical standard of these Leica lenses.<\/p>\n<p>Now the question is: is it worth it? For a Leica lens the price is comparably fair, especially as I don&#8217;t see this lens loosing much value in the future, but compared to buying a new Samyang 85mm 1.4 AF, <a href=\"https:\/\/phillipreeve.net\/blog\/review-sony-fe-85-mm-1-8\/\">Sony FE 85mm 1.8<\/a> or <a href=\"https:\/\/phillipreeve.net\/blog\/review-viltrox-85-mm-f-1-8-stm-af-pfu-rbmh\/\">Viltrox 85mm 1.8<\/a> it isn&#8217;t exactly cheap either.<br \/>\nThese lenses are using newer technology like aspherical elements, floating elements design as well as <em>auto focus<\/em> and are optically &#8220;superior&#8221; in most areas while actually being cheaper.<br \/>\nSo as a Sony user to choose this Leica lens over the alternatives you must really like the rendering or the build quality\/red dot.<\/p>\n<p>If you are looking for a fast <em>manual focus<\/em> portrait lens with nice mechanical design (or you are in the M-mount eco system anyway) the <a href=\"https:\/\/phillipreeve.net\/blog\/review-voigtlander-75mm-f1-5-vm\/\">Voigtlander VM 75mm 1.5 Nokton<\/a> is probably the better lens for most (me included) these days. But this also boils down to your <a href=\"https:\/\/phillipreeve.net\/blog\/building-a-lens-kit\/\">kit<\/a> to some degree: I bought this 90mm 2.0 to have something longer to pair with a 50mm lens where I don&#8217;t see a 75mm lens fit and the list of good lenses in the 85-100mm realm for M-mount is a really short one.<\/p>\n<figure id=\"attachment_28376\" aria-describedby=\"caption-attachment-28376\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-28376\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2021\/04\/Leica_Summicro_90mm_2.0_pre_asph_M10.jpg\" alt=\"\" width=\"800\" height=\"450\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2021\/04\/Leica_Summicro_90mm_2.0_pre_asph_M10.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2021\/04\/Leica_Summicro_90mm_2.0_pre_asph_M10-300x169.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2021\/04\/Leica_Summicro_90mm_2.0_pre_asph_M10-768x432.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-28376\" class=\"wp-caption-text\">Leica M10 with Leica 90mm 2.0 Summicron M (pre Asph)<\/figcaption><\/figure>\n<p>Also, it is to me one of the best looking lenses, no matter whether you pair it with a Sony or a Leica camera, but this probably shouldn&#8217;t be your main reason to buy it \ud83d\ude42<\/p>\n<p><em>This pre-Asph version usually starts selling for <strong>$800<\/strong> at <a href=\"https:\/\/www.ebay.com\/sch\/i.html?LH_CAds=&amp;_ex_kw=&amp;_fpos=&amp;_fspt=1&amp;_mPrRngCbx=1&amp;_nkw=summicron+90&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=5337820268&amp;toolid=10001&amp;customid=&amp;mkevt=1\" target=\"_blank\" rel=\"noopener\">ebay.com<\/a> (advertisement\/affiliate link).
