It is also notable, that the aperture ring turns in the &#8220;wrong&#8221; direction, as was also the case with the <a

At maximum aperture I measure 2.0 EV which improves to 1.5 EV at f\/2.8. Already at f\/2.8 it is only 1.0 EV and further improves to 0.7 EV at f\/8.0.<br \/>\nThe Voigtlander lens shows similar values wide open and about 0.3 EV lower ones stopped down, so all in all not a bad performance here.<\/p>\n<figure id=\"attachment_31052\" aria-describedby=\"caption-attachment-31052\" style=\"width: 1026px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-31052\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2022\/02\/MS_73mm_1.5_Sonnetar.png\" alt=\"\" width=\"1026\" height=\"766\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2022\/02\/MS_73mm_1.5_Sonnetar.png 1026w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2022\/02\/MS_73mm_1.5_Sonnetar-300x224.png 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2022\/02\/MS_73mm_1.5_Sonnetar-800x597.png 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2022\/02\/MS_73mm_1.5_Sonnetar-768x573.png 768w\" sizes=\"auto, (max-width: 1026px) 100vw, 1026px\" \/><figcaption id=\"caption-attachment-31052\" class=\"wp-caption-text\">MS-Optics 73mm 1.5 Sonnetar<\/figcaption><\/figure>\n<p><em>It is recommended to have a look at <a href=\"https:\/\/phillipreeve.net\/blog\/vignetting-graphs-explained\/\">this article<\/a> first to get an idea how this brightness graph works.<\/em><\/p>\n<h3>optical vignetting<\/h3>\n<p>Very fast yet compact lenses usually show a significant amount of optical vignetting.

Generally low astigmatism at wider apertures, which often is the case with Miyazaki&#8217;s designs.<br \/>\nAt f\/2.8 we should see high resolution and contrast across the whole frame and really good performance at f\/5.6 except for the extreme corners where there also seems to be a fair amount of astigmatism stopped down.

As usual I am showing you the worst part of the frame here.<\/p>\n<p>Unfortunately the corners suffer a bit due to filter stack induced field curvature. Stopped down to f\/11 and focused a bit closer might yield better results than you see here.<\/p>\n<p>Let us see in the next section how the lens performs on a camera with a thinner filter

was not reached on my M10 at wider apertures, this is always a risk with lenses with infinity hard stop, which is why I am not a big fan of such hard stops.<br \/>\nA small adjustment of the coma-adjustment-ring could fix this (I changed the setting from 3.0 m to ~ 2.5 m), I am showing you the sharpness series after adjustment here.<\/p>\n<p>By f\/8.0 the lens looks really good across the whole frame, so when the light allows for it or a tripod is available it is a good performer for landscape or achitecture shooting.<br \/>\nInterestingly with this lens I also don&#8217;t see the high astigmatism in the corners shown in the MTF-graphs.<\/p>\n<p>Nevertheless, the <a href=\"https:\/\/phillipreeve.net\/blog\/review-voigtlander-75mm-f1-5-vm\/\">Voigtlander VM 75mm 1.5 Nokton<\/a> yields higher resolution and contrast, especially at wider apertures.<\/p>\n<h3>portrait distance (2.0 m)<\/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 (and also focus shift) out of the equation.<\/p>\n<figure id=\"attachment_20406\"

any lens to look bad if you push it hard enough and a slight change of scenario can affect results a lot.<\/p>\n<p>Nevertheless, it was easy to make the MS-Optics 73mm 1.5 look bad here, as it is not

I was hoping for something like the <a href=\"https:\/\/phillipreeve.net\/blog\/review-jupiter-9-85mm-2-0\/\">Jupiter-9 85mm 2.0<\/a> (meaning soft and smooth) but in a more compact package and with modern coatings.<br \/>\nIn close focus scenarios soft and smooth is usually what you get, but when you focus on something farther away it gets busy and funky very fast.<br \/>\nAnd then there are those strange coma\/spherical aberration artefacts at maximum aperture which I find very distracting and tried to avoid, so I see it more as an 73mm f\/1.8 lens to be honest.<\/p>\n<p>Strong longitudinal chromatic aberrations are also something I try to avoid in my lenses and here the MS-Optics 73mm 1.5 Sonnetar is not doing a great job either.<\/p>\n<p>If you like the look of the images or you really want the smallest and lightest lens in class maybe the MS-Optics 73mm 1.5 is exactly what you are looking for, but these are the only reasons I can think of getting this over the great <a href=\"https:\/\/phillipreeve.net\/blog\/review-voigtlander-75mm-f1-5-vm\/\">Voigtlander VM 75mm 1.5 Nokton<\/a>.<\/p>\n<figure id=\"attachment_27716\" aria-describedby=\"caption-attachment-27716\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-27716\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2021\/02\/ms-optics_73mm_1.5_Sonnetar_title.jpg\" alt=\"ms-optics ms-optical 73mm 1.5 sonnetar f\/1.5 fast summilux leica m10 24mp 42mp review sharpness contrast resolution lateral ca chromatic aberration aberrations\" width=\"800\" height=\"450\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2021\/02\/ms-optics_73mm_1.5_Sonnetar_title.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2021\/02\/ms-optics_73mm_1.5_Sonnetar_title-300x169.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2021\/02\/ms-optics_73mm_1.5_Sonnetar_title-768x432.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-27716\" class=\"wp-caption-text\">MS-Optics 73mm 1.5 Sonnetar on Leica M10<\/figcaption><\/figure>\n<p><em>You can find this lens at <a href=\"https:\/\/www.japanexposures.com\/shop\/camera-lens\/?currency=USD\">japanexposures.com<\/a> or on <a href=\"https:\/\/www.ebay.com\/sch\/i.html?_from=R40&amp;_trksid=p2380057.m570.l1313&amp;_nkw=ms-optics+73mm&amp;_sacat=0&amp;mkrid=711-53200-19255-0&amp;siteid=0&amp;mkcid=1&amp;campid=5337820130&amp;toolid=20008&amp;mkevt=1\">ebay.com<\/a> (advertisement\/affiliate link) but don&#8217;t expect it to be always available.
