of the Sony cameras. Both come with Leica-M mount though and from the outside can only be distinguished by a small &#8220;FE-PLUS&#8221; mark on the bayonet. The FE-Plus version also has a click stop at f\/11 that was absent on the Leica version I tried.<br \/>\nIn the beginning there was also a version with an obvious ring flare when used wide open. As far as I know only few were made and all &#8220;FE-Plus&#8221; versions feature the improved flare resistance.<\/p>\n<figure id=\"attachment_17641\" aria-describedby=\"caption-attachment-17641\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-17641\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/7artisaus_28mm_1.4_feplus_detail_2.jpg\" alt=\"7artisans leica summulix 28mm 1.4 f\/1.4 wide angle fast 42mp sony feplus resolution contrast coma review\" width=\"800\" height=\"450\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/7artisaus_28mm_1.4_feplus_detail_2.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/7artisaus_28mm_1.4_feplus_detail_2-300x169.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/7artisaus_28mm_1.4_feplus_detail_2-768x432.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-17641\" class=\"wp-caption-text\">FEplus marking on bayonet<\/figcaption><\/figure>\n<p>Apart from this both versions look exactly the same and share the following specifications:<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>Diameter: 60mm<\/li>\n<li>Field of view: 75\u00b0 (diagonally)<\/li>\n<li>Length: 69mm (+adapter)<\/li>\n<li>Weight: 490g (+adapter, without hood and caps)<\/li>\n<li>Filter Diameter: 52mm<\/li>\n<li>Number of Aperture Blades: 13 (rounded)<\/li>\n<li>Elements\/Groups: 11\/9<\/li>\n<li>Close Focusing Distance: 0.7 m<\/li>\n<li>Maximum Magnification: 1:20 (measured)<\/li>\n<li>Mount: Leica-M<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><em>The lens is available from the <a href=\"https:\/\/7artisans.store\/products\/7artisans-m28mm-f1-4?ref=05rrjwls\">manufacturer&#8217;s shop<\/a>, <a href=\"https:\/\/bhpho.to\/2NCqOZt\">B&amp;H<\/a>, <a href=\"https:\/\/amzn.to\/2Lyk7GB\">amazon.com<\/a>\/<a href=\"https:\/\/amzn.to\/2XiCHHk\">amazon.de<\/a> <a href=\"https:\/\/www.ebay.com\/sch\/i.html?LH_CAds=&amp;_ex_kw=&amp;_fpos=&amp;_fspt=1&amp;_mPrRngCbx=1&amp;_nkw=7artisans+28mm+1.4&amp;_sacat=625&amp;_sadis=&amp;_sop=12&amp;_udhi=&amp;_udlo=&amp;_fosrp=1&amp;mkrid=711-53200-19255-0&amp;siteid=0&amp;mkcid=1&amp;campid=5337820268&amp;toolid=10001&amp;customid=&amp;mkevt=1\">ebay.com<\/a>\/<a href=\"https:\/\/www.ebay.de\/sch\/i.html?_ex_kw=&amp;_mPrRngCbx=1&amp;_nkw=7artisans+28mm+1.4&amp;_sacat=625&amp;_sop=12&amp;_udhi=&amp;_udlo=&amp;_fosrp=1&amp;mkrid=707-53477-19255-0&amp;siteid=77&amp;mkcid=1&amp;campid=5337820268&amp;toolid=10001&amp;customid=&amp;mkevt=1\">ebay.de<\/a> for about <strong>$436<\/strong> (advertisement\/affiliate links)<br \/>\nWhen buying on ebay make sure you buy the FE-plus version.<br \/>\nIf you want to make sure you get the right one you can always use <a href=\"http:\/\/rover.ebay.com\/rover\/1\/711-53200-19255-0\/1?ff3=4&amp;pub=5575156171&amp;toolid=10001&amp;campid=5337820268&amp;customid=&amp;mpre=https%3A%2F%2Fwww.ebay.com%2Fitm%2F7artisans-28mm-F1-4-Large-Aperture-Lens-for-leica-m-mount-fe-plus-Version%2F173811237618%3Fhash%3Ditem2877f502f2%3Ag%3AqpIAAOSwJ%7E5b96ov%26frcectupt%3Dtrue\">this link<\/a> pointing you to the official store.<\/em><\/p>\n<h1>Handling \/ Build Quality<\/h1>\n<figure id=\"attachment_17640\" aria-describedby=\"caption-attachment-17640\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-17640\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/7artisaus_28mm_1.4_feplus_detail.jpg\" alt=\"7artisans leica summulix 28mm 1.4 f\/1.4 wide angle fast 42mp sony feplus resolution contrast coma review\" width=\"800\" height=\"534\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/7artisaus_28mm_1.4_feplus_detail.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/7artisaus_28mm_1.4_feplus_detail-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/7artisaus_28mm_1.4_feplus_detail-768x513.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-17640\" class=\"wp-caption-text\">7artisans 28mm 1.4<\/figcaption><\/figure>\n<p>From the outer apperance this looks very much like a Leica M lens including the famous red dot. Markings are yellow\/white (seem to be slightly engraved and filled with paint) focus ring has an absolutely perfect resistance (just like the <a href=\"https:\/\/phillipreeve.net\/blog\/review-leica-90mm-2-0-summicron-m\/\">Leica Summicron 90mm 2.0 pre Asph<\/a> I used to own) and turns slightly more than 90\u00b0 from the minimum focus distance of 0.7 m to infinity.<br \/>\nThe aperture ring has full stop click stops which I think is a good design decision. It makes changing the aperture to the desired value without looking at the lens very easy.<br \/>\nThe aperture ring is oh so slightly wobbly if you try to move it in an axial direction. I am sure most of you would never notice this as normal people would not try to move the aperture ring like that, but I have never used a 7artisans lens before so I wanted to know where they stand in terms of build quality. At a first look (after a few weeks of usage) they are pretty good.<\/p>\n<p>The lens features a rangefinder coupling which can be adjusted yourself using a small screwdriver. Being an owner of an M-mount camera now I cannot stretch enough what a wonderful design decision this is: the lens can easily be adjusted to be perfectly calibrated to your rangefinder camera and give best possible results without sending it in. I wish every M-mount lens would offer this.<br \/>\nIf you don&#8217;t intend to use this lens on a rangefinder camera you can also remove the brass part and save some (very little) weight.<\/p>\n<figure id=\"attachment_17642\" aria-describedby=\"caption-attachment-17642\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-17642 size-full\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/7artisaus_28mm_1.4_feplus_hood-e1553343901268.jpg\" alt=\"7artisans leica summulix 28mm 1.4 f\/1.4 wide angle fast 42mp sony feplus resolution contrast coma review\" width=\"800\" height=\"378\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/7artisaus_28mm_1.4_feplus_hood-e1553343901268.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/7artisaus_28mm_1.4_feplus_hood-e1553343901268-300x142.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/7artisaus_28mm_1.4_feplus_hood-e1553343901268-768x363.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-17642\" class=\"wp-caption-text\">Square rectangular hood<\/figcaption><\/figure>\n<p>My lens also shipped with a rectangular lens hood (with hole for using with a rangefinder camera) and a focus tab with adhesive on the back that you can put on the focus ring if you like to.<\/p>\n<h1>Vignetting<\/h1>\n<h3><strong>light falloff<br \/>\n<\/strong><\/h3>\n<p><em><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-17734 size-full\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/vignetting_7artisans_28mm_1.4.png\" alt=\"7artisans leica summulix 28mm 1.4 f\/1.4 wide angle fast 42mp sony feplus resolution contrast coma review vignetting light fall off vignette\" width=\"750\" height=\"610\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/vignetting_7artisans_28mm_1.4.png 750w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/vignetting_7artisans_28mm_1.4-300x244.png 300w\" sizes=\"auto, (max-width: 750px) 100vw, 750px\" \/><br \/>\n<\/em><\/p>\n<p>Wide open there is strong light falloff of roughly 2.5 EV, stopped down to f\/2.0 this improves to 2.0 EV, stopped down to f\/2.8 it is 1.9 EV and pretty much stays at that value on stopping down further.

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

The focus shift effect is a bit more visible here between f\/2.0 and f\/4.0 though, so either use live view (if possible) or stop down to f\/5.6 in the first place.<br \/>\nThe midframe looks actually significantly better on the Leica sensor, I see about a two stop improvement.<br \/>\nThe corners look slightly worse between f\/1.4 and f\/4.0 on the Leica.<br \/>\nBest across frame performance is also reached at f\/8.0 on the Leica sensor, but the midframe surely looks better on this camera.<\/p>\n<p>I said on the Sony f\/2.8 yields usable resolution across frame, on the Leica the midframe is better at f\/2.8 but the corners are worse, so I would rather stop down to f\/4.0 or better f\/5.6 here (to also get rid of the focus shift effect).<br \/>\nFor many applications the better midframe instead of corner resolution will be favorable though.<\/p>\n<p><em>Focus shift (see corresponding section) had not been taken into account for these shots, so with stopped down focusing you can get slightly better results at f\/2.0 to f\/4.0.<\/em><\/p>\n<h3><strong>Compared to:<\/strong> Voigtlander VM 35mm 1.7 + 5m PCX<\/h3>\n<figure id=\"attachment_17639\" aria-describedby=\"caption-attachment-17639\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-17639 size-full\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/7artisans_28mm_1.4_vm_35_1.7_5m_pcx-e1553298245152.jpg\" alt=\"7artisans leica summulix 28mm 1.4 f\/1.4 wide angle fast 42mp sony feplus resolution contrast coma review\" width=\"800\" height=\"344\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/7artisans_28mm_1.4_vm_35_1.7_5m_pcx-e1553298245152.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/7artisans_28mm_1.4_vm_35_1.7_5m_pcx-e1553298245152-300x129.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/7artisans_28mm_1.4_vm_35_1.7_5m_pcx-e1553298245152-768x330.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-17639\" class=\"wp-caption-text\">7artisans 28mm 1.4 and Voigtlander VM 35mm 1.7 Ultron with 5m PCX filter attached<\/figcaption><\/figure>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-17778 size-full\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/Sharpness_voigtlander_35mm_1.7_5m_2-1.png\" alt=\"7artisans leica summulix 28mm 1.4 f\/1.4 wide angle fast 42mp sony feplus resolution contrast coma review\" width=\"800\" height=\"2482\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/Sharpness_voigtlander_35mm_1.7_5m_2-1.png 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/Sharpness_voigtlander_35mm_1.7_5m_2-1-97x300.png 97w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/Sharpness_voigtlander_35mm_1.7_5m_2-1-768x2383.png 768w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/Sharpness_voigtlander_35mm_1.7_5m_2-1-413x1280.png 413w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/p>\n<p>As you know the <a href=\"https:\/\/phillipreeve.net\/blog\/voigtlander-ultron-11-7-35-mm-review\/\">Voigtlander VM 35mm 1.7 Ultron<\/a> + <a href=\"https:\/\/phillipreeve.net\/blog\/rangefinder-wide-angle-lenses-on-a7-cameras-problems-and-solutions\/\">5m PCX filter<\/a> is my lens of choice in this focal length range for quite some time now, offering a very balanced package of maximum aperture, bokeh and stopped down across frame sharpness.<\/p>\n<p>The 7artisans lens holds up well in this comparison. The center performance wide open is comparable. Interestingly close to the center different structures show moir\u00e9 when comparing both lenses.<\/p>\n<p>The Voigtlander shows much better midframe but much worse corners at wider apertures and the corners don&#8217;t improve as fast. So the Voigtlander lens with correction filter needs to be stopped down to f\/8.0 to show the same across frame performance as the 7artisans lens at f\/4.0.<br \/>\nUp to you what you prefer, there is definetly something to be said for either approach.<\/p>\n<p><em>The corner crops have been pushed in post to reveal more details.<\/em><\/p>\n<h3>portrait distance<\/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-2-review-7artisans-28mm-1-4-fe-plus-39425\"><li class=\"active\"><a href=\"#ert_pane2-0\" data-toggle=\"tab\">f\/1.4<\/a><\/li><li class=\"\"><a href=\"#ert_pane2-1\" data-toggle=\"tab\">f\/2.0<\/a><\/li><\/ul><\/div><div style=\"clear:both;width: 100%;\"><ul class=\"tab-content\" id=\"oscitas-restabcontent-2-review-7artisans-28mm-1-4-fe-plus-39425\"><li class=\"tab-pane active\" id=\"ert_pane2-0\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-17670 size-full\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/middistance_midframe_f1.4.jpg\" alt=\"7artisans leica summulix 28mm 1.4 f\/1.4 wide angle fast 42mp sony feplus resolution contrast coma review\" width=\"800\" height=\"450\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/middistance_midframe_f1.4.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/middistance_midframe_f1.4-300x169.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/middistance_midframe_f1.4-768x432.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/li><li class=\"tab-pane \" id=\"ert_pane2-1\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-17671 size-full\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/middistance_midframe_f2.0.jpg\" alt=\"7artisans leica summulix 28mm 1.4 f\/1.4 wide angle fast 42mp sony feplus resolution contrast coma review\" width=\"800\" height=\"450\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/middistance_midframe_f2.0.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/middistance_midframe_f2.0-300x169.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/03\/middistance_midframe_f2.0-768x432.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/li><\/ul><\/div><\/div><br \/>\n<span style=\"color: #808080;\"><em>100% crops from outer midframe center, A7rII<\/em><\/span><\/p>\n<p>For taking a full body portrait in landscape orientation you need a distance of about ~2.0 to 2.5 m to the subject.<br \/>\nThe midzone dip we can see at infinity starts to have a visible influence at these distances, too.

So far there was no 28mm lens with these specs that appealed to me available, so I was using the <a href=\"https:\/\/phillipreeve.net\/blog\/voigtlander-ultron-11-7-35-mm-review\/\">Voigtlander VM 35mm 1.7<\/a> + <a href=\"https:\/\/phillipreeve.net\/blog\/rangefinder-wide-angle-lenses-on-a7-cameras-problems-and-solutions\/\">5m PCX<\/a> for this task.<br \/>\nI also tried my luck with the <a href=\"https:\/\/phillipreeve.net\/blog\/review-slrmagic-35mm-1-2-cine\/\">SLRmagic 35mm 1.2<\/a>, but it is a rather basic design without aspherical elements and bokeh wasn\u2019t completely to my liking.<br \/>\nThe optical design of this 28mm 1.4 though looked very interesting and more advanced: aspherical element, ED elements, high refractive elements.

\/><\/li><\/ul><\/div><\/div>\n<p>&nbsp;<\/p>\n<p>I tried to give you a thorough basis here to decide whether you like the bokeh rendering or not. This is a matter of personal taste and will also heavily depend on what you use this lens for.<br \/>\nI was using this lens on several occasions to see how it works for me in many different scenarios. In the end there are way more pictures where I like the bokeh compared to those where I don\u2019t like it.<\/p>\n<h1>Sunstars<\/h1>\n<p>This is the second lens with 13 rounded aperture blades I reviewed (first one being the <a href=\"https:\/\/phillipreeve.net\/blog\/review-slrmagic-35mm-1-2-cine\/\">SLRmagic 35mm 1.2<\/a>). With that higher number of blades the correct and equidistant spacing between these is very important to get decent sunstars.<br \/>\nI was very surprised to see we get clear and respectable sunstars between f\/5.6 and f\/11. Judging by my experiences with other lenses I really did not expect that. They are actually very similar to those of the <a href=\"https:\/\/phillipreeve.net\/blog\/review-sony-fe-24mm-1-4-gm\/\">Sony FE 24mm 1.4 GM<\/a> or <a href=\"https:\/\/phillipreeve.net\/blog\/review-sony-fe-85mm-1-4-gm\/\">85mm 1.4 GM<\/a> (both featuring 11 rounded blades).<\/p>\n<p><div class=\"osc-res-tab tabbable   osc-tabs-left\"><div

a bit closer for best performance. This is most noticeable at close range, less so at infnity.

What was I expecting? Not much to be honest.<br \/>\nBut after thoroughly testing the lens and using it in the field I can stand before you and tell you I was wrong. Very wrong.<\/p>\n<p>First thing you notice is this lens does not feel like your cheap sub $500 chinese lens (I am looking at you, <a href=\"https:\/\/phillipreeve.net\/blog\/review-slrmagic-35mm-1-2-cine\/\">SLRmagic 35mm 1.2<\/a>). In terms of build quality it seems to be much closer to the Zeiss Loxia or newer Voigtlander lenses.<\/p>\n<p>I liked the Bokeh in most cases a lot. I consider it to be quite similar to the <a href=\"https:\/\/phillipreeve.net\/blog\/voigtlander-ultron-11-7-35-mm-review\/\">VM 35mm 1.7<\/a>. Like most fast wide angle lenses it struggles at full body portrait distance (when transition zone and background overlap). Still, it holds itself up well here and I would need to compare it directly to the Nikon AF-S 28mm 1.4E or the gigantic Sigma 28mm 1.4 Art to see if those actually fare better at these distances.<\/p>\n<p>Also from f\/2.8 onwards the image quality at infinty is pretty much on par with the highly regarded Voigtlander <a href=\"https:\/\/phillipreeve.net\/blog\/voigtlander-ultron-11-7-35-mm-review\/\">VM 35mm 1.7<\/a> when coupled with the <a href=\"https:\/\/phillipreeve.net\/blog\/rangefinder-wide-angle-lenses-on-a7-cameras-problems-and-solutions\/\">5m PCX filter<\/a> (my lens of choice in this focal length range for infinity shooting), making it a very versatile and capable landscape and architecture lens.<\/p>\n<p>There are a few things I don&#8217;t like: the midzone dip between f\/1.4 to f\/2.0 is definetly something to watch out for.<br \/>\nFlare resistance is not bad, but not as good as the <a href=\"https:\/\/phillipreeve.net\/blog\/voigtlander-ultron-11-7-35-mm-review\/\">VM 35mm 1.7<\/a> either (I see that as class leading though, so nothing be to ashamed of).<br \/>\nThere is noticeable green color cast in the corners. Again, similar to the <a href=\"https:\/\/phillipreeve.net\/blog\/voigtlander-ultron-11-7-35-mm-review\/\">VM 35mm 1.7<\/a>, but something not found on super fast native lenses like the <a href=\"https:\/\/phillipreeve.net\/blog\/voigtlander-40mm-f1-2-nokton-aspherical-rolling-review\/\">Voigtlander 40mm 1.2 E<\/a>.<br \/>\nThe minimum focus distance of 0.7m really ain&#8217;t that great, so I advise you to couple this lens with a close focus helicoid adapter like the <a href=\"https:\/\/phillipreeve.net\/blog\/review-voigtlander-vm-e-close-focus-adapter\/\">Voigtlander VM-E close focus adapter<\/a> or the one from Hawk&#8217;s Factory I am currently using. This will increase the entry price a bit if you don&#8217;t already own one though.<\/p>\n<p>I see this lens as a very welcome addition to the sparse line up of 28mm lenses optimized for E-mount cameras. As you can probably tell from the sample images I had great fun using this lens and have added it to my kit.<\/p>\n<p>This lens feels a lot like a <a href=\"https:\/\/phillipreeve.net\/blog\/review-zeiss-zm-35mm-1-4-t-distagon\/\">Zeiss ZM 35mm 1.4<\/a> with 28mm and for about a fourth the price, so I am tempted to call it an actual bargain. After 3 months of regular usage I still like this lens a lot and it often finds a way in my bag.<\/p>\n<p><em><strong>Update: Performance on Leica M10<\/strong><\/em><\/p>\n<figure id=\"attachment_24336\" aria-describedby=\"caption-attachment-24336\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-24336\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2020\/01\/DSC05541.jpg\" alt=\"\" width=\"800\" height=\"450\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2020\/01\/DSC05541.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2020\/01\/DSC05541-300x169.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2020\/01\/DSC05541-768x432.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-24336\" class=\"wp-caption-text\">7Artisans 28mm 1.4 FE+ on Leica M10<\/figcaption><\/figure>\n<p>Many of you have been asking in the comments which lens to get if they intend to use this lens on Sony and Leica cameras. After investigating the performance on the M10 I tend to say: get the FE-Plus version. There really isn&#8217;t much you loose when doing so.<br \/>\nBy the way, I really like the option to adjust the rangefinder coupling myself. I adjusted it once for infinity and afterwards was spot on at every distance. Just be careful of the focus shift between f\/2.0 and f\/4.0 to get best possible results.<\/p>\n<p><em>The lens is available from the <a href=\"https:\/\/7artisans.store\/products\/7artisans-m28mm-f1-4?ref=05rrjwls\">manufacturer&#8217;s shop<\/a>, <a href=\"https:\/\/bhpho.to\/2NCqOZt\">B&amp;H<\/a>, <a href=\"https:\/\/amzn.to\/2Lyk7GB\">amazon.com<\/a>\/<a href=\"https:\/\/amzn.to\/2XiCHHk\">amazon.de<\/a> <a href=\"https:\/\/www.ebay.com\/sch\/i.html?LH_CAds=&amp;_ex_kw=&amp;_fpos=&amp;_fspt=1&amp;_mPrRngCbx=1&amp;_nkw=7artisans+28mm+1.4&amp;_sacat=625&amp;_sadis=&amp;_sop=12&amp;_udhi=&amp;_udlo=&amp;_fosrp=1&amp;mkrid=711-53200-19255-0&amp;siteid=0&amp;mkcid=1&amp;campid=5337820268&amp;toolid=10001&amp;customid=&amp;mkevt=1\">ebay.com<\/a>\/<a href=\"https:\/\/www.ebay.de\/sch\/i.html?_ex_kw=&amp;_mPrRngCbx=1&amp;_nkw=7artisans+28mm+1.4&amp;_sacat=625&amp;_sop=12&amp;_udhi=&amp;_udlo=&amp;_fosrp=1&amp;mkrid=707-53477-19255-0&amp;siteid=77&amp;mkcid=1&amp;campid=5337820268&amp;toolid=10001&amp;customid=&amp;mkevt=1\">ebay.de<\/a> for about <strong>$436<\/strong> (advertisement\/affiliate links)<br \/>\nWhen buying on ebay make sure you buy the FE-plus version.<br \/>\nIf you want to make sure you get the right one you can always use <a href=\"http:\/\/rover.ebay.com\/rover\/1\/711-53200-19255-0\/1?ff3=4&amp;pub=5575156171&amp;toolid=10001&amp;campid=5337820268&amp;customid=&amp;mpre=https%3A%2F%2Fwww.ebay.com%2Fitm%2F7artisans-28mm-F1-4-Large-Aperture-Lens-for-leica-m-mount-fe-plus-Version%2F173811237618%3Fhash%3Ditem2877f502f2%3Ag%3AqpIAAOSwJ%7E5b96ov%26frcectupt%3Dtrue\">this link<\/a> pointing you to the official store.<\/em><\/p>\n<h1>Alternatives<\/h1>\n<h2>E-mount<\/h2>\n<p><a href=\"https:\/\/phillipreeve.net\/blog\/review-laowa-28mm-1-2-ffii-argus-the-worlds-fastest-28mm-lens\/\"><em><strong>Laowa 28mm 1.2 Argus:<\/strong><\/em><\/a><br \/>\nThe Laowa lens is even faster and I especially like its high contrast at wider apertures which in combination with the f\/1.2 aperture and the wide angle view makes this a great choice for <a href=\"https:\/\/phillipreeve.net\/blog\/how-to-create-environmental-portraits\/\">environmental portraiture<\/a>.
