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

\/><\/li><\/ul><\/div><\/div><span style=\"color: #999999;\"><em>Sony A7rII | 1.0 m focus distance<\/em><\/span><\/p>\n<p>The theoretical maximum aperture an F-mount lens can have has been calculated to f\/1.17 and f\/1.2 is awfully close to that. The problem with these theoretical values is, that you usually cannot easily reach them in practice.<\/p>\n<p>As you can see in the center the circle looks cut at f\/1.2. This is because the rear element is actually not perfectly round due to the space needed for the aperture lever. This is the case for all of Nikon&#8217;s f\/1.2 lenses. I am actually not sure if this should be considered optical vignetting or mechanical vignetting.<\/p>\n<p>In 2023 &#8211; to my utmost surprise &#8211; Cosina released the <a href=\"https:\/\/phillipreeve.net\/blog\/review-voigtlander-55mm-1-2-sl-iis-nokton-the-last-f-mount-lens\/\">Voigtl\u00e4nder 55mm 1.2 SL IIs Nokton<\/a> for the Nikon F-mount. This lens features a special mechanical design (more on that in its review) that allows for a normal, perfectly round rear element. This is actually the only real f\/1.2 lens for the F-mount, released 64 years after its introduction.<\/p>\n<p>As we are operating at the limit of the lens mount optical vignetting is also very high &#8211; comparable to the <a href=\"https:\/\/phillipreeve.net\/blog\/comparison-super-fast-50mm-m-mount-lenses\/\">Super Fast 50mm M-mount Lenses<\/a>. The 50mm 1.2 lenses for the bigger Canon EF-mount (<a href=\"https:\/\/phillipreeve.net\/blog\/review-canon-ef-50mm-1-2-l-usm\/\">Canon EF 50mm 1.2L<\/a> and <a href=\"https:\/\/phillipreeve.net\/blog\/review-samyang-50mm-1-2-xp\/\">Samyang 50mm 1.2 XP<\/a>) show less optical vignetting.<\/p>\n<p>The 9 aperture blades are surely a benefit over the <a href=\"https:\/\/phillipreeve.net\/blog\/review-nikon-nikkor-55mm-1-2-ai-the-first-f-1-2-f-mount-lens\/\">Nikon 55mm 1.2<\/a> with only 7. The amount of optical vignetting between these two is also very similar. The <a href=\"https:\/\/phillipreeve.net\/blog\/review-nikon-58mm-1-2-ai-noct-nikkor\/\">58mm 1.2 Noct-Nikkor<\/a> shows a little less optical vignetting and also cleaner circles without distinct edges, which leads to a calmer bokeh.<\/p>\n<h2>Sharpness<\/h2>\n<h3>Glow \/ Spherical Aberration<\/h3>\n<p>Many modern fast lenses offer astonishingly high image quality at their maximum aperture, but this is usually not the case for fast lenses from earlier times. At wider apertures these lenses often create some &#8220;<em>glow<\/em>&#8220;. This Nikon 50mm 1.2 with its design from 1978 is also one of those lenses. If we were looking for a more technical term for <em>&#8220;glow&#8221;<\/em> it would be <em>undercorrected spherical aberration<\/em>.<\/p>\n<p>Spherical aberration is the only classic <a href=\"https:\/\/en.wikipedia.org\/wiki\/Optical_aberration\">lens aberration<\/a> that has an effect on the center of the frame. It will make your image appear softer and add some additional <em>&#8220;glow&#8221;<\/em> to already bright parts of the image. It is also an effect similar to what you get when using a <a href=\"https:\/\/phillipreeve.net\/blog\/diffusion-filters-are-they-useful\/\">diffusion\/mist filter<\/a>.<\/p>\n<p>Some people may like this softer rendering for portraiture, but then many others simply see this as bad image quality. You can find a few image sets shot at f\/1.2, f\/1.4 and f\/2.0 (where most of the glow\/spherical aberration is gone) here, so you can better judge, if this effect is for you.<\/p>\n<p><div

And by my experience, for fast lenses like this, that usually wasn&#8217;t infinity, because these are often situations where you can stop the lens down a bit.<\/p>\n<p>At f\/1.2 to f\/1.4 the lens is soft everywhere and on this bright day we can see huge artefacts around point light sources.<\/p>\n<p>Stopping down to f\/2.0 increases the contrast significantly and the midframe area already looks decent. These huge artefacts are also mostly gone. The corners are still nothing to write home about.<\/p>\n<p>I didn&#8217;t adjust for focus shift here, so the f\/2.8 center crop actually looks worse than the f\/2.0 one. It takes stopping down to f\/5.6 for the increased depth of field to catch up with the focus shift. For the corners to look good stopping down to f\/11 is not a bad idea.<\/p>\n<p>The <a href=\"https:\/\/phillipreeve.net\/blog\/review-nikon-nikkor-55mm-1-2-ai-the-first-f-1-2-f-mount-lens\/\">55mm 1.2<\/a> showed a very similar performance whereas the <a href=\"https:\/\/phillipreeve.net\/blog\/review-nikon-58mm-1-2-ai-noct-nikkor\/\">58mm 1.2 Noct<\/a> looks a bit worse at wider apertures thanks to stronger field curvature.<\/p>\n<h3><b>Portrait 1<\/b><b>.4 m (42mp Sony A7rII)<\/b><\/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 out of the equation.<\/p>\n<figure id=\"attachment_20406\" aria-describedby=\"caption-attachment-20406\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-20406\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/08\/portrait_distance.png\" alt=\"\" width=\"800\" height=\"533\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/08\/portrait_distance.png 3000w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/08\/portrait_distance-300x200.png 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/08\/portrait_distance-768x512.png 768w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2019\/08\/portrait_distance-800x533.png 800w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-20406\" class=\"wp-caption-text\">positions of crops in the frame<\/figcaption><\/figure>\n<p>We will be looking at 100% crops from the 42mp Sony A7rII.<\/p>\n<p><strong>f\/1.2 &lt;&#8212;&gt;

This 50mm 1.2 also comes as Ai-s version with 9 instead of 7 aperture blades, the flare resistance is a bit better and I also found it to generally perform better at f\/1.2 and f\/1.4. The reason for the latter might also be sample variation though.<\/p>\n<p><em>I will reuse the following paragraph from my review of the <a href=\"https:\/\/phillipreeve.net\/blog\/review-nikon-nikkor-55mm-1-2-ai-the-first-f-1-2-f-mount-lens\/\">Nikon 55mm 1.2<\/a>:<\/em><br \/>\nIn today&#8217;s times this lens is for those that are looking for something different. Who are bored by the &#8220;optical perfection&#8221; of modern lenses and are looking for a specific look, that &#8220;vintage rendering&#8221;. If you are among those, this 50mm 1.2 is an affordable entry ticket. You should also be aware this lens is not as easy to use as modern ones. It is optimized for close to mid distances at f\/1.2. For full body portraits your subject better be in the center, otherwise it is probably a good idea to stop down a bit.<\/p>\n<p>Modern f\/1.2 lenses perform great from their maximum aperture for pretty much any task, with these older lenses that is not the case. Understanding their strengths and weaknesses is necessary to make best use of them and maybe this review can help with that.<\/p>\n<p><em>buy from <a href=\"https:\/\/www.ebay.com\/sch\/i.html?_from=R40&amp;_trksid=p2334524.m570.l1313&amp;_nkw=nikon+50mm+1.2&amp;_sacat=0&amp;_odkw=voigtl%C3%A4nder+55mm+1.2+nokton&amp;_osacat=0&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?_from=R40&amp;_trksid=p2334524.m570.l1313&amp;_nkw=nikon+50mm+1.2&amp;_sacat=0&amp;_odkw=voigtl%C3%A4nder+55mm+1.2+nokton&amp;_osacat=0&amp;mkcid=1&amp;mkrid=707-53477-19255-0&amp;siteid=77&amp;campid=5337820268&amp;toolid=20008&amp;mkevt=1\">ebay.de<\/a> (advertisement\/affiliate links) starting at <strong>$400<\/strong><\/em><\/p>\n<h2>Alternatives<\/h2>\n<p>I reviewed a lot of fast 50mm lenses but most of them have been M-mount lenses.

If it doesn&#8217;t have to be an &#8220;original&#8221; vintage lens, I think this is a better choice than this 50mm and the 55mm 1.2 thanks to featuring 9 rounded aperture blades, more nicely shaped
