This Voigtl\u00e4nder 28mm 1.9 Ultron had been released in 2001, so it can still be considered one of Cosina&#8217;s earlier rangefinder lenses and there are some notable differences compared to their latest M-mount lenses.<\/p>\n<p>Being an M39 lens means you need an M39-&gt;M-mount adapter to use this lens on your modern digital M-mount camera. These adapters add another variable to the equation that may screw up your rangefinder coupling and the lens will most likely not sit perfectly centered on your camera.<br \/>\nThe benefit is that you are also able to mount this lens on some older rangefinder cameras that feature the M39 mount (also known as LTM = Leica Thread Mount).<\/p>\n<p>Most of Cosina&#8217;s current black lenses are made from matte anodized aluminium. Here the situation is a bit different though: the 28mm 1.9 Ultron looks a lot like the Leica &#8220;black paint&#8221; cameras and lenses, and with a lot of use it will show a similar kind of wear (&#8220;brassing&#8221; as some people call it), but the lens is too light to be made of actual brass. Going by its weight I am guessing it is also made from aluminium. This sample is in amazing condition and it doesn&#8217;t show any of that wear though.<\/p>\n<figure id=\"attachment_45125\" aria-describedby=\"caption-attachment-45125\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-45125\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2023\/09\/Voigtlander_28mm_1.9_Ultron_Focus_Lever.jpg\" alt=\"voigtl\u00e4nder 28mm 1.9 ultron leica review contrast sharpness vignetting 24mp m10 42mp m11 resolution m39 ltm thread mount\" width=\"800\" height=\"533\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2023\/09\/Voigtlander_28mm_1.9_Ultron_Focus_Lever.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2023\/09\/Voigtlander_28mm_1.9_Ultron_Focus_Lever-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2023\/09\/Voigtlander_28mm_1.9_Ultron_Focus_Lever-768x512.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-45125\" class=\"wp-caption-text\">removable focus lever<\/figcaption><\/figure>\n<p>There have been several different casing designs of Cosina lenses over the past two decades.

Without going too much into technical details optical vignetting leads to the truncation of light circles towards the borders of the frame.<br \/>\nIn the center of the frame almost every lens will render a perfect circle, but only lenses with very low optical vignetting will keep this shape in the corners.<br \/>\nSo in the following comparison we move from the center (left) to the extreme corner (right) and see how the shape of the light circle changes.<\/p>\n<div class=\"osc-res-tab tabbable   osc-tabs-left\"><div style=\"clear:both;width: 100%;\"><ul class=\"nav osc-res-nav nav-tabs

stopping down to at least f\/5.6 to really get rid of the purple fringing.<\/p>\n<p>What about the comparison to the newer <a

And this is one such case. After having used all three generations of this lens that have been released between 2001 and 2021, I see clear improvements with every generation.<\/p>\n<p>Contrast, resolution and also flare resistance have been greatly increased, at the same time size and weight have been significantly reduced. Quite the engineering achievement.<\/p>\n<p>So at the end of the day, I think this lens is mainly interesting to those that need a fast 28mm lens that still makes use of an M39 connection for their analogue camera, or those that are looking for a bit of that &#8220;vintage&#8221; wide open glow.<\/p>\n<p><em>This lens has been discontinued long time ago, you can mainly find it on <a href=\"https:\/\/www.ebay.com\/sch\/i.html?_from=R40&amp;_trksid=p4432023.m570.l1313&amp;_nkw=voigtl%C3%A4nder+28mm+1.9&amp;_sacat=0&amp;mkcid=1&amp;mkrid=711-53200-19255-0&amp;siteid=0&amp;campid=5337820268&amp;toolid=20008&amp;mkevt=1\">ebay.com<\/a> | <a href=\"https:\/\/www.ebay.de\/sch\/i.html?_from=R40&amp;_trksid=p4432023.m570.l1313&amp;_nkw=voigtl%C3%A4nder+28mm+1.9&amp;_sacat=0&amp;mkcid=1&amp;mkrid=707-53477-19255-0&amp;siteid=77&amp;campid=5337820268&amp;toolid=20008&amp;mkevt=1\">ebay.de<\/a> (advertisement\/affiliate links) for ~<strong>$500<\/strong><\/em><\/p>\n<h2>Alternatives<\/h2>\n<p>You can find all my reviews of 28mm M-mount lens reviews <a href=\"https:\/\/phillipreeve.net\/blog\/lenses\/leica-lenses\/\">here<\/a>, so I will only talk about the most obvious alternatives in more detail.<\/p>\n<p><a href=\"https:\/\/phillipreeve.net\/blog\/review-voigtlander-ultron-28mm-2-0\/\"><strong>Voigtlander VM 28mm 2.0 Ultron MK II:<\/strong><\/a><br \/>\nFor most people this newer lens is the better choice as it offers higher contrast, higher resolution, better flare resistance, a better minimum focus distance while at the same time being smaller and lighter.
