If you have seen one of the Simera or Eureka lenses you will immediately notice that Thypoch went a different route here, as they chose a knurled focus ring and a rather unusual font.<\/p>\n<p>The focus ring could have a little higher resistance but as is typical for Thypoch&#8217;s M-mount lenses it features a click stop at 0.7 m. It turns around 100\u00b0 from the minimum focus distance of 0.5 m to infinity.<\/p>\n<p>The aperture ring has small wings similar to the <a href=\"https:\/\/phillipreeve.net\/blog\/vm_40mm_1-4_nokton_mc\/\">Voigtl\u00e4nder VM 40mm 1.4 Nokton<\/a> and features equidistant half-stop click-stops as it should be.<\/p>\n<p>Because of the size of this lens both focus and aperture ring are narrow and have almost the same diameter, so there is certainly some risk grabbing the wrong one.<\/p>\n<figure id=\"attachment_82145\" aria-describedby=\"caption-attachment-82145\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-82145\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2026\/01\/Thypoch_21mm_3.5_Ksana_Epoch_rear.jpg\" alt=\"thypoch ksana epoch 73 coating 21mm 3.5 compact leica m10 m11 m9 m8 m10r review 42mp 24mp 61mp contrast sharpness bokeh vignetting limited\" width=\"800\" height=\"533\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2026\/01\/Thypoch_21mm_3.5_Ksana_Epoch_rear.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2026\/01\/Thypoch_21mm_3.5_Ksana_Epoch_rear-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2026\/01\/Thypoch_21mm_3.5_Ksana_Epoch_rear-768x512.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-82145\" class=\"wp-caption-text\">bayonet and rangefinder coupling<\/figcaption><\/figure>\n<p>There are not a lot of non-moving parts to grab this lens to mount or unmount it, so most of the time you will grab it by the focus ring and rotate it until you hit one of the hard stops.&nbsp;&nbsp;<\/p>\n<p>This Thypoch 21mm 3.5 brings up the 28\/90mm frameline pair and because it is so small there is hardly any rangefinder blockage.&nbsp;<\/p>\n<figure id=\"attachment_82143\" aria-describedby=\"caption-attachment-82143\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-82143\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2026\/01\/Thypoch_21mm_3.5_Ksana_Epoch_Comparison_Voigtlander_VM_21mm_3.5_Color_Skopar_Type_I_II.jpg\" alt=\"thypoch ksana epoch 73 coating 21mm 3.5 compact leica m10 m11 m9 m8 m10r review 42mp 24mp 61mp contrast sharpness bokeh vignetting limited\" width=\"800\" height=\"259\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2026\/01\/Thypoch_21mm_3.5_Ksana_Epoch_Comparison_Voigtlander_VM_21mm_3.5_Color_Skopar_Type_I_II.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2026\/01\/Thypoch_21mm_3.5_Ksana_Epoch_Comparison_Voigtlander_VM_21mm_3.5_Color_Skopar_Type_I_II-300x97.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2026\/01\/Thypoch_21mm_3.5_Ksana_Epoch_Comparison_Voigtlander_VM_21mm_3.5_Color_Skopar_Type_I_II-768x249.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-82143\" class=\"wp-caption-text\">Thypoch 21mm 3.5 Ksana | Voigtl\u00e4nder VM 21mm 3.5 Color-Skopar<\/figcaption><\/figure>\n<p>This is a very small lens: a bit shorter than the <a href=\"https:\/\/phillipreeve.net\/blog\/review-voigtlander-vm-21mm-3-5-color-skopar\/\">Voigtl\u00e4nder VM 21mm 3.5 Color-Skopar<\/a>, actually closer to the older Voigtl\u00e4nder VM 21mm 4.0 Color-Skopar.

I would understand that design choice when it comes to portrait lenses. A 21mm 3.5 wide angle lens is something I would expect most people to use for landscape or architecture shooting and maybe some for street photography though and here I wouldn&#8217;t embrace such kind of lens flares. But maybe I am the minority here, so please tell me in the comment section what you think of this design choice.<\/p>\n<p>If you are looking for an as compact as possible 21mm M-mount lens this is surely worth a closer look, be sure to also check out the Alternatives section below though.<\/p>\n<div dir=\"auto\">\n<p><em>buy from <a href=\"https:\/\/store.thypoch.com\/collections\/all?ref=lyiftukn\">manufacturer&#8217;s shop<\/a> (use code PRNET for 5% discount) | <a href=\"https:\/\/www.ebay.com\/sch\/i.html?_nkw=thypoch+21mm+3.5&amp;_sacat=0&amp;_from=R40&amp;_trksid=m570.l1313&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?_nkw=thypoch+21mm+3.5&amp;_sacat=0&amp;_from=R40&amp;_trksid=p4624852.m570.l1313&amp;mkcid=1&amp;mkrid=707-53477-19255-0&amp;siteid=77&amp;campid=5337820268&amp;toolid=20008&amp;mkevt=1\">ebay.de<\/a> | <a href=\"https:\/\/www.bhphotovideo.com\/c\/search?N=0&amp;InitialSearch=yes&amp;Ntt=thypoch%2021mm%203.5&amp;BI=21073&amp;KBID=18855&amp;SID=DFF&amp;DFF=d50\">B&amp;H<\/a> (advertisement\/affiliate links) for <strong>$549<\/strong><\/em><\/p>\n<div dir=\"auto\">\n<h2>Alternatives<\/h2>\n<p><a href=\"https:\/\/phillipreeve.net\/blog\/review-voigtlander-vm-21mm-3-5-color-skopar\/\"><em><strong>Voigtlander VM 21mm 3.5 Color-Skopar Type I\/II:<\/strong><\/em><\/a><br \/>\nI already compared this Thypoch lens to the 21mm 3.5 Color-Skopar in most of the sections above.
