When comparing this 40mm 2.0 (and also the 28mm 2.8) to e.g. my similarly old <a href=\"https:\/\/phillipreeve.net\/blog\/review-leica-90mm-2-0-summicron-m\/\">Leica 90mm 2.0<\/a> from 1987 (or modern Voigtl\u00e4nder and TTArtisan lenses) the build quality does not feel as nice though: the focus rings of the Minolta lenses have a rather low resistance and both their helicoids show a bit of slack. I don&#8217;t know if they have always been like that or if it is simply because they have been used a lot over the past 40 years though.<\/p>\n<p>The focus ring turns ~110\u00b0 from its minimum focus distance of 0.8 m to infinity. The aperture ring features equidistantly spaced half-a-stop click-stops between f\/2.0 and f\/16.<\/p>\n<p>All the markings are engraved and filled with paint and most parts of the outer barrel feel like they are made from metal. I am not 100% sure about the small focus tab though, it feels like that one is made from plastic.<\/p>\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-1-review-minolta-40mm-2-0-m-rokkor-61029\"><li class=\"active\"><a href=\"#ert_pane1-0\" data-toggle=\"tab\">hood folded<\/a><\/li><li class=\"\"><a href=\"#ert_pane1-1\" data-toggle=\"tab\">hood extended<\/a><\/li><\/ul><\/div><div style=\"clear:both;width: 100%;\"><ul class=\"tab-content\" id=\"oscitas-restabcontent-1-review-minolta-40mm-2-0-m-rokkor-61029\"><li class=\"tab-pane active\" id=\"ert_pane1-0\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-43554\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2023\/08\/Minolta_40mm_2.0_M-Rokkor_Hood_Retracted.jpg\" alt=\"minolta 40mm 2.0 m-rokkor leica review contrast sharpness vignetting 24mp m10 42mp m11 resolution\" width=\"800\" height=\"533\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2023\/08\/Minolta_40mm_2.0_M-Rokkor_Hood_Retracted.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2023\/08\/Minolta_40mm_2.0_M-Rokkor_Hood_Retracted-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2023\/08\/Minolta_40mm_2.0_M-Rokkor_Hood_Retracted-768x512.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/li><li class=\"tab-pane \" id=\"ert_pane1-1\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-43553\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2023\/08\/Minolta_40mm_2.0_M-Rokkor_Hood_Extended.jpg\" alt=\"minolta 40mm 2.0 m-rokkor leica review contrast sharpness vignetting 24mp m10 42mp m11 resolution\" width=\"800\" height=\"533\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2023\/08\/Minolta_40mm_2.0_M-Rokkor_Hood_Extended.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2023\/08\/Minolta_40mm_2.0_M-Rokkor_Hood_Extended-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2023\/08\/Minolta_40mm_2.0_M-Rokkor_Hood_Extended-768x512.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/li><\/ul><\/div><\/div><span style=\"color: #999999;\"><em>Minolta 40mm 2.0 with rubber hood attached<\/em><\/span><\/p>\n<p>As was already the case for the <a href=\"https:\/\/phillipreeve.net\/blog\/review-minolta-m-rokkor-90mm-4-0\/\">90mm 4.0<\/a>, there is also a retractable rubber screw-in hood available for this 40mm lens.<\/p>\n<p>The Minolta 40mm 2.0 M-Rokkor brings up the correct 40mm framelines on the Leica CL and the Minolta CLE whereas it brings up the 50mm framelines on the Leica M10\/M6.

On the Leica M10 I did not adjust the focus setting for focus shift when stopping down, which is why the f\/5.6 center crop looks worse than the f\/4.0 one. When looking at the midframe we see a steady improvement on stopping down though, as would be expected.<\/p>\n<p>Now on the higher resolution A7rII the crops with the lens stopped down looked so bad because of focus shift, I had to re-run the series with adjusted focus at every aperture setting. Now here we see a steady improvement in the center, but the midframe actually looks worse at f\/5.6 than at f\/4.0. Why is that?<br \/>\nWith some lenses the focus shift does not affect all parts of the frame the same way, this Minolta 40mm 2.0 seems to be one of those lenses.<\/p>\n<p>When it comes to the corner performance I would recommend to stop this lens down to f\/8.0 or f\/11 regardless of camera, if the light levels allow for that.<\/p>\n<p>Now if we compare the results in this category to those of the <a href=\"https:\/\/phillipreeve.net\/blog\/vm_40mm_1-4_nokton_mc\/\">Voigtl\u00e4nder VM 40mm 1.4 Nokton<\/a>, the Minolta does look a bit better resolution-wise in the corners and even more so in the midframe at wider apertures. Stopped down the Nokton manages to catch up though.<\/p>\n<p>Now lens designs as small as this one always spot some compromises, but we should also keep in mind this lens was designed in the 70s, so it is half a century old now. No one was even dreaming of high resolution digital sensors at that time. Considering all that, this lens holds up pretty well even today.<\/p>\n<h3><b>Portrait <\/b><b>1.2 m (24mp Sony A7III\/Leica M10)<\/b><\/h3>\n<p>For portraiture it isn&#8217;t so important how flat the field is, it is more interesting to see what the sharpness is like when focused at different parts of the frame to take field curvature out of the equation.<\/p>\n<figure id=\"attachment_20406\" aria-describedby=\"caption-attachment-20406\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-20406\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/08\/portrait_distance.png\" alt=\"\" width=\"800\" height=\"533\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/08\/portrait_distance.png 3000w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/08\/portrait_distance-300x200.png 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/08\/portrait_distance-768x512.png 768w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/08\/portrait_distance-800x533.png 800w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-20406\" class=\"wp-caption-text\">positions of crops in the frame<\/figcaption><\/figure>\n<p>We will be looking at 100% crops from the 24mp Sony A7III and the Leica M10.

and Zeiss ZM\/Loxia lenses, leading to pretty nice sunstars between f\/2.8 and f\/11. At f\/2.0 and f\/16 the opening is perfectly round, so no sunstars at these settings.<br \/>\nIf you want to learn more about this topic have a look at <a

lightweight lenses and this Minolta 40mm 2.0 M-Rokkor is as compact and lightweight as it gets for a 40mm f\/2.0 lens.<\/p>\n<p>For many years this was actually considered a bit of a hidden gem thanks to decent optics while being small and affordable. In 2024 I don&#8217;t really see it as being that great of a deal anymore though, as you have to pay at least $350 for one in good condition &#8211; more than for a brand new <a href=\"https:\/\/phillipreeve.net\/blog\/vm_40mm_1-4_nokton_mc\/\">Voigtl\u00e4nder VM 40mm 1.4 Nokton<\/a>. The Voigtl\u00e4nder lens may be noticeably heavier, but it is also similarly sized while being one stop faster.<\/p>\n<p>Except for being lighter, what are the benefits of this Minolta lens by comparison? It has less distortion and a bit more even across frame sharpness at wider apertures. In terms of contrast it is not as punchy as the Voigtl\u00e4nder lens, but some of you may actually prefer that for a slightly softer rendering.<\/p>\n<p>At the end of the day this Minolta 40mm 2.0 M-Rokkor is a cute little lens that won&#8217;t weigh you down and will be useful for a lot of applications.<\/p>\n<p><em>buy from <a href=\"https:\/\/www.ebay.com\/sch\/i.html?_from=R40&amp;_trksid=p2334524.m570.l1313&amp;_nkw=minolta+40mm+2+m&amp;_sacat=0&amp;LH_TitleDesc=0&amp;_odkw=minolta+40mm+2.0&amp;_osacat=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=p2334524.m570.l1313&amp;_nkw=%28%27minolta%27%2C%27leica%27%29+40mm+2.0&amp;_sacat=0&amp;LH_TitleDesc=0&amp;rt=nc&amp;_odkw=%28minolta%2Cleica%29+40mm+2.0&amp;_osacat=0&amp;LH_PrefLoc=2&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) starting at <strong>$350<\/strong><\/em><\/p>\n<h2>Alternatives<\/h2>\n<p>There are not that many 40mm lenses for M-mount.
