The Mr. Ding 50mm 1.1 Noxlux became a favorite of mine and many others, can they repeat that success with this 35mm 1.8 Pactcron?

combined with very unfavourable field curvature. This will often lead to the corners being in focus even though they shouldn&#8217;t be.&nbsp;<\/p>\n<p>Personally, I find this rendering rather distracting. But there are many compact M-mount wide angle lenses with a similar behaviour (e.g. the <a href=\"https:\/\/phillipreeve.net\/blog\/review-light-lens-lab-35mm-2-0-eight-element\/\">Light Lens Lab 35mm 2.0 8e<\/a> or the <a href=\"https:\/\/phillipreeve.net\/blog\/review-artizlab-35mm-1-4-classic\/\">Artizlab 35mm 1.4 Classic<\/a> or the <a href=\"https:\/\/phillipreeve.net\/blog\/review-ms-optics-28mm-2-0-apoqualia\/\">MS-Optics 28mm 2.0 Apoqualia<\/a>) including many vintage Leica lenses, that people pay a lot of money for, so this rendering must have some fans after all.<\/p>\n<h2>Sunstars<\/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

So depending on which category you find yourself in, you will either love or hate this lens.&nbsp;<\/p>\n<p>Generally this Mr. Ding 35mm 1.8 Pactcron falls in the &#8220;vintage\/classic&#8221; category. While it actually shows high contrast and resolution in the focal plane from wide open (unlike the <a href=\"https:\/\/phillipreeve.net\/blog\/review-artizlab-35mm-1-4-classic\/\">Artizlab 35mm 1.4 Classic<\/a>) and makes use of modern coatings (unlike the <a href=\"https:\/\/phillipreeve.net\/blog\/review-light-lens-lab-35mm-2-0-eight-element\/\">Light Lens Lab 35mm 2.0 8e<\/a>) it shows strong field curvature and Coma at wider apertures, leading to a rather strong falloff towards the corners. I also included several samples showing the effect this has on the bokeh rendering at mid to long focus distances.<\/p>\n<p>As said before, this type of rendering is rather popular among the vintage wide angle rangefinder lenses, so if you are looking for a 35mm M-mount lens with vintage characteristics and you value the use of brass and the black paint finish this lens might be for you.<\/p>\n<p><em>You can order this lens from the <a href=\"https:\/\/mrdingstudio.com\/products\/mr-ding-35-1-8-for-leica-mount?ref=G_RCnAFR27Ntin&amp;variant=43635608912053\">official homepage<\/a> (advertisement\/affiliate link) for <strong>$699<\/strong><\/em><\/p>\n<h2>Alternatives<\/h2>\n<p>There are countless 35mm options for M-mount available. Others which fall in the &#8220;vintage\/classic&#8221; category are the Voigtl\u00e4nder VM 35mm 2.0 Ultron &#8211; which I haven&#8217;t reviewed yet &#8211; and the Voigtl\u00e4nder <a href=\"https:\/\/phillipreeve.net\/blog\/review-voigtlander-35mm-1-4-nokton-e-classic\/\">VM 35mm 1.4 Nokton Classic<\/a>. The <a href=\"https:\/\/phillipreeve.net\/blog\/review-ms-optics-35mm-1-4-apoqualia\/\">MS-Optics 35mm 1.4 Apoqualia<\/a> also has similar characteristics at f\/2.0, but it is a rare and expensive lens.<\/p>\n<p>Another recent competitor is the <a href=\"https:\/\/phillipreeve.net\/blog\/review-artizlab-35mm-1-4-classic\/\">Artizlab 35mm 1.4 Classic<\/a> from China. Generally I found this Mr. Ding 35mm 1.8 to perform a bit better (especially when it comes to contrast\/resolution and flare resistance), but the Artizlab is lighter, smaller and cheaper while being a bit faster.<\/p>\n<p>If you are looking for a compact lens with a more classic rendering which is more affordable be also sure to have a look at the <a href=\"https:\/\/phillipreeve.net\/blog\/vm_40mm_1-4_nokton_mc\/\">Voigtl\u00e4nder VM 40mm 1.4 Nokton MC<\/a>.<\/p>\n<p>If you are looking for a technically near perfect 35mm 2.0 lens you should have a look at the noticeably bigger and heavier <a href=\"https:\/\/phillipreeve.net\/blog\/review-voigtlander-vm-35mm-2-0-apo-lanthar\/\">Voigtl\u00e4nder VM 35mm 2.0 Apo-Lanthar<\/a>.<\/p>\n<p>You can
