With a wider lens like this these are more helpful compared to their longer lenses. I would still prefer ditching that thing altogether and giving us a bigger focus ring instead.<\/p>\n<p>The focus ring rotat<span style=\"color: #000000;\">es ~120\u00b0 fr<\/span>om infinity to the minimum focus distance of 0.23 m &#8211; again the focus throw is too short at closer distances though. The resistance is even and actually quite nice. What I like about the focus ring is that it has a distinct click stop at the 0.7 m setting, so you will notice leaving the rangefinder-coupled range.<\/p>\n<p>The aperture ring features a small de-click lever at the bottom. Its resistance is high, so I don&#8217;t think there is a high likelihood to accidentally change its setting. The stops are not spaced equidistantly and the click stops are also a bit random &#8211; 1\/3rd of a stop clicks between f\/1.4 and f\/4.0, half stops between f\/4.0 and f\/5.6 and full stops between f\/5.6 and f\/16 &#8211; which makes figuring out how far you stopped the lens down going by the clicks and without looking at it also rather difficult. I really hope Thypoch will optimize this for future lenses.<\/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-thypoch-21mm-1-4-simera-39561\"><li class=\"active\"><a href=\"#ert_pane1-0\" data-toggle=\"tab\">infinity no hood<\/a><\/li><li class=\"\"><a href=\"#ert_pane1-1\" data-toggle=\"tab\">infinity hood<\/a><\/li><li class=\"\"><a href=\"#ert_pane1-2\" data-toggle=\"tab\">MFD no hood<\/a><\/li><li class=\"\"><a href=\"#ert_pane1-3\" data-toggle=\"tab\">MFD hood<\/a><\/li><\/ul><\/div><div style=\"clear:both;width: 100%;\"><ul class=\"tab-content\" id=\"oscitas-restabcontent-1-review-thypoch-21mm-1-4-simera-39561\"><li class=\"tab-pane active\" id=\"ert_pane1-0\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-74645\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_RF_Blockage_Infinity.jpg\" alt=\"thypoch simera 21mm 1.4 fast portrait wide angle leica m10 m11 m9 m8 m10r review 42mp 24mp 61mp contrast sharpness bokeh vignetting\" width=\"800\" height=\"573\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_RF_Blockage_Infinity.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_RF_Blockage_Infinity-300x215.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_RF_Blockage_Infinity-768x550.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-74646\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_RF_Blockage_Infinity_Hood.jpg\" alt=\"thypoch simera 21mm 1.4 fast portrait wide angle leica m10 m11 m9 m8 m10r review 42mp 24mp 61mp contrast sharpness bokeh vignetting\" width=\"800\" height=\"573\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_RF_Blockage_Infinity_Hood.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_RF_Blockage_Infinity_Hood-300x215.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_RF_Blockage_Infinity_Hood-768x550.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/li><li class=\"tab-pane \" id=\"ert_pane1-2\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-74647\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_RF_Blockage_MFD.jpg\" alt=\"thypoch simera 21mm 1.4 fast portrait wide angle leica m10 m11 m9 m8 m10r review 42mp 24mp 61mp contrast sharpness bokeh vignetting\" width=\"800\" height=\"573\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_RF_Blockage_MFD.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_RF_Blockage_MFD-300x215.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_RF_Blockage_MFD-768x550.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/li><li class=\"tab-pane \" id=\"ert_pane1-3\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-74648\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_RF_Blockage_MFD_Hood.jpg\" alt=\"thypoch simera 21mm 1.4 fast portrait wide angle leica m10 m11 m9 m8 m10r review 42mp 24mp 61mp contrast sharpness bokeh vignetting\" width=\"800\" height=\"573\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_RF_Blockage_MFD_Hood.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_RF_Blockage_MFD_Hood-300x215.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_RF_Blockage_MFD_Hood-768x550.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/li><\/ul><\/div><\/div><span style=\"color: #999999;\"><em>Rangefinder blockage<\/em><\/span><\/p>\n<p>Similar to the <a href=\"https:\/\/phillipreeve.net\/blog\/review-thypoch-simera-28mm-1-4\/\">28mm 1.4 Simera<\/a>&nbsp;also this 21mm 1.4 is a rear focus lens which means the length of the lens does not change when focusing.<\/p>\n<p>It shouldn&#8217;t come as a surprise that the rangefinder blockage is still significant with this lens.

Due to the performance in the corners the lens actually looks best when stopped down to f\/8.0 here. The <a href=\"https:\/\/phillipreeve.net\/blog\/review-voigtlander-vm-21mm-1-4-nokton\/\">Voigtl\u00e4nder VM 21mm 1.4 Nokton<\/a> on the other hand looks least as good at f\/2.8 as this Thypoch lens does at f\/8.0.<\/p>\n<p>When looking at the performance on the Sony A7rII the M-mount version of the <a href=\"https:\/\/phillipreeve.net\/blog\/review-voigtlander-vm-21mm-1-4-nokton\/\">Voigtl\u00e4nder VM 21mm 1.4 Nokton<\/a> performed pretty bad: midzone dip at wider apertures and mediocre corners. This Thypoch 21mm 1.4 Simera only shows a slight midzone dip and the corners actually look better than on the Leica. On the Sony A7rII this lens shows great across frame performance from f\/4.0.<\/p>\n<p>As the Thypoch lenses are often availabe for different mounts my guess is they might be designed for an &#8220;average&#8221; filter thickness, allowing them to perform well enough on various camera systems. Good news for those among us that use more than one camera system.<\/p>\n<h3>close 0.23 m, 1:6.6 (42mp Sony A7rII)<em><br \/>\n<\/em><\/h3>\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-4-review-thypoch-21mm-1-4-simera-78549\"><li class=\"active\"><a href=\"#ert_pane4-0\" data-toggle=\"tab\">f\/1.4<\/a><\/li><li class=\"\"><a href=\"#ert_pane4-1\" data-toggle=\"tab\">f\/2.0<\/a><\/li><li class=\"\"><a href=\"#ert_pane4-2\" data-toggle=\"tab\">f\/2.8<\/a><\/li><li class=\"\"><a href=\"#ert_pane4-3\" data-toggle=\"tab\">f\/4.0<\/a><\/li><\/ul><\/div><div style=\"clear:both;width: 100%;\"><ul class=\"tab-content\" id=\"oscitas-restabcontent-4-review-thypoch-21mm-1-4-simera-78549\"><li class=\"tab-pane active\" id=\"ert_pane4-0\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-74649\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_Sharpness_Close_R2_1.4.jpg\" alt=\"thypoch simera 21mm 1.4 fast portrait wide angle leica m10 m11 m9 m8 m10r review 42mp 24mp 61mp contrast sharpness bokeh vignetting\" width=\"800\" height=\"534\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_Sharpness_Close_R2_1.4.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_Sharpness_Close_R2_1.4-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_Sharpness_Close_R2_1.4-768x513.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/li><li class=\"tab-pane \" id=\"ert_pane4-1\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-74650\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_Sharpness_Close_R2_2.0.jpg\" alt=\"thypoch simera 21mm 1.4 fast portrait wide angle leica m10 m11 m9 m8 m10r review 42mp 24mp 61mp contrast sharpness bokeh vignetting\" width=\"800\" height=\"534\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_Sharpness_Close_R2_2.0.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_Sharpness_Close_R2_2.0-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_Sharpness_Close_R2_2.0-768x513.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/li><li class=\"tab-pane \" id=\"ert_pane4-2\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-74651\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_Sharpness_Close_R2_2.8.jpg\" alt=\"thypoch simera 21mm 1.4 fast portrait wide angle leica m10 m11 m9 m8 m10r review 42mp 24mp 61mp contrast sharpness bokeh vignetting\" width=\"800\" height=\"534\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_Sharpness_Close_R2_2.8.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_Sharpness_Close_R2_2.8-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_Sharpness_Close_R2_2.8-768x513.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/li><li class=\"tab-pane \" id=\"ert_pane4-3\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-74652\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_Sharpness_Close_R2_4.0.jpg\" alt=\"thypoch simera 21mm 1.4 fast portrait wide angle leica m10 m11 m9 m8 m10r review 42mp 24mp 61mp contrast sharpness bokeh vignetting\" width=\"800\" height=\"534\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_Sharpness_Close_R2_4.0.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_Sharpness_Close_R2_4.0-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/06\/Thypoch_21mm_1.4_Simera_Sharpness_Close_R2_4.0-768x513.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/li><\/ul><\/div><\/div><em><span style=\"color: #999999;\">Sony A7rII | Thypoch 21mm 1.4&nbsp;

out. Normally lenses with such a high number (16) of rounded aperture blades do not create distinct sunstars, but here the production tolerances for the diaphragm seem to be pretty tight, as we see nice sunstars with an even length of the rays from f\/5.6 to f\/16.<br \/>\nIf you want to know more about sunstars have a look at <a

At first I thought this might end up being a boring review to write, should they actually perform more or less the same.<\/p>\n<p>Interestingly that isn&#8217;t the case. This Thypoch lens does show some improvements when it comes to CA and Coma correction and their engineers also managed to make it a bit smaller and lighter while focusing much closer &#8211; which is always welcome.<\/p>\n<p>In terms of sharpness at infinity &#8211; at least when used on an M-mount camera &#8211; it did not impress me as much as the<a href=\"https:\/\/phillipreeve.net\/blog\/review-voigtlander-vm-21mm-1-4-nokton\/\"> Voigtl\u00e4nder VM 21mm 1.4 Nokton<\/a> though whose mechanical design I also prefer. This time the Thypoch lens is also a bit more expensive.<\/p>\n<p>I told you about the small differences and they may push you towards one or the other. At the end of the day these are both very capable fast 21mm lenses and you cannot really go wrong with either of them.<\/p>\n<p><em>buy from <a href=\"https:\/\/store.thypoch.com\/collections\/all?ref=lyiftukn\">manufacturer&#8217;s shop<\/a> (use code PRNET for free shipping) | <a href=\"https:\/\/www.ebay.com\/sch\/i.html?_nkw=simera+21mm+1.4&amp;_sacat=0&amp;_from=R40&amp;_trksid=p4432023.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=simera+21mm+1.4&amp;_sacat=0&amp;_from=R40&amp;_trksid=p4432023.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:\/\/bhpho.to\/445YmUS\">B&amp;H<\/a> (advertisement\/affiliate links) for <strong>$999<\/strong><\/em><\/p>\n<h2>Alternatives<\/h2>\n<p><em><strong><a href=\"https:\/\/phillipreeve.net\/blog\/review-voigtlander-vm-21mm-1-4-nokton\/\">Voigtl\u00e4nder VM 21mm 1.4 Nokton:<\/a><br \/>\n<\/strong><\/em>In pretty much all of the categories above I compared these lenses. When I saw their optical designs being eerily similar I was expecting the same being true for their performance as well, but there are indeed some differences (but also a lot of similarities).<br \/>\nThe Voigtl\u00e4nder was still a bit sharper in my testing on a Leica camera, especially at infinity and I also greatly prefer its mechanical design. The Thypoch corrects coma and longitudinal CA better and is a bit smaller and lighter.&nbsp;<br \/>\nWhen I compared the Thypoch 75mm 1.4 Simera to the Voigtl\u00e4nder VM 75mm 1.5 Nokton the Thypoch was my clear recommendation. Here the situation is not as obvious, especially because the Thypoch is a hundred bucks more expensive than the Voigtl\u00e4nder.

Its optical design is simpler (only 10 elements with 2 aspherical surfaces) but it also features a floating elements design &#8211; it only focuses down to 0.7 m though, so I am not sure how useful it actually is. I wouldn&#8217;t be surprised if we see a lukewarm MK II update with improved minimum focus distance soon, as we have already seen for the 35mm 1.4 FLE and the 50mm 1.4 FLE.<br \/>\nAs usual it is hard to find reviews with an actual assessment of this Leica lens&#8217; performance, but what I saw didn&#8217;t give me any reason to consider picking it over this Thypoch or the Voigtl\u00e4nder 21mm 1.4.
