The Sigma 14mm 1.8 DG HSM Art was the fastest 14mm lens for DSLRs when it was released in 2017 and this Sigma 14mm 1.4 DG Art is the fastest 14mm lenses for mirrorless cameras since 2023. This lens&#8217; purpose is obviously astrophotography and on paper it is the ideal lens for milky way and especially aurora shooting. By my experience these fast ultra wide angle lenses have very high sample variation though, did Sigma manage to solve that issue?

At that point I lost the motivation to try further samples and ending up on that shop&#8217;s black list in the process.<\/p>\n<p>Because of this lens&#8217; ultra wide angle view I also made an adjustment to the <a href=\"https:\/\/phillipreeve.net\/blog\/how-to-check-how-decentered-your-lens-is\/\">centering test procedure<\/a> I usually use. As this lens comes with a rotateable tripod collar, I used that to rotate the lens with camera attached, thereby taking a picture of the same object with all four corners of the lens. This way it is 100% ensured that neither the angle nor the distance to the subject change even one bit.&nbsp;<\/p>\n<p>I decided to still put together this article with my findings, as this is generally a lens you cannot find a lot of useful information on.

The benefit of this Sigma 14mm 1.4 is that it improves more on stopping down, so from f\/5.6 it shows about 0.7 EV less vignetting.

This means, if you shoot both these lenses set to their maximum aperture with the same shutter speed and ISO setting, the corners of this 1.4 lens will hardly be brighter than those of the older 1.8 lens.

this is the most important category for a lens like this. Considering this is the only 14mm lens as fast as f\/1.4, what you see above could be considered a solid performance and can also be seen as an improvement over the <a

curvature and I actually had to focus on the corners for them to look good (central part and midframe are actually out of focus in the full pictures belonging to those crops you see above).<\/p>\n<p>The <a href=\"https:\/\/phillipreeve.net\/blog\/review-sony-fe-14mm-1-8-gm\/\">Sony FE 14mm 1.8 GM<\/a> and <a

The <a href=\"https:\/\/phillipreeve.net\/blog\/review-sony-fe-14mm-1-8-gm\/\">Sony FE 14mm 1.8 GM<\/a> and <a href=\"https:\/\/phillipreeve.net\/blog\/review-sony-fe-16mm-1-8-g\/\">Sony FE 16mm 1.8 G<\/a> are a little bit slower, but they are significantly smaller and lighter. Taking into account front cap and tripod collar, this 14mm 1.4 weighs 4 times as much as the <a href=\"https:\/\/phillipreeve.net\/blog\/review-sony-fe-16mm-1-8-g\/\">Sony FE 16mm 1.8 G<\/a> and 2.5 times as much as the <a href=\"https:\/\/phillipreeve.net\/blog\/review-sony-fe-14mm-1-8-gm\/\">Sony FE 14mm 1.8 GM<\/a>.&nbsp;<\/p>\n<p>Now some people prioritize maximum image quality and don&#8217;t care too much about size and weight. In the past Sigma managed to satisfy these kind of customers with lenses like the <a href=\"https:\/\/phillipreeve.net\/blog\/review-sigma-40mm-1-4-art\/\">Sigma 40mm 1.4 DG HSM Art<\/a>, <a href=\"https:\/\/phillipreeve.net\/blog\/review-sigma-105mm-1-4-dg-hsm-art-the-bokeh-master\/\">Sigma 105mm 1.4 DG HSM Art<\/a> and lately the <a href=\"https:\/\/phillipreeve.net\/blog\/review-sigma-135mm-1-4-art-dg-the-actual-bokeh-master\/\">Sigma 135mm 1.4 DG Art<\/a>. Here I am not so sure they accomplished that, as the vignetting figures are too high (especially compared to the predecessor) and field curvature also seems to be a bit of a problem.<\/p>\n<p><em>If you happen to own (or even want to sell) an actually good copy of this 14mm 1.4, please leave a message in the comment section.<\/em><\/p>\n<\/div>\n<\/div>\n<p><em>buy from <a href=\"https:\/\/amzn.to\/3YNIV0J\">amazon.com<\/a> | <a href=\"https:\/\/amzn.to\/3UzIBQM\">amazon.de<\/a> | <a href=\"https:\/\/www.ebay.com\/sch\/i.html?_from=R40&amp;_trksid=p2334524.m570.l1313&amp;_nkw=sigma+14mm+1.4+&amp;_sacat=0&amp;_odkw=laowa+15mm+2.0&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=sigma+14mm+1.4+&amp;_sacat=0&amp;_odkw=sony+fe+14mm+1.8+gm&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> | <a href=\"https:\/\/bhpho.to\/43rqMpJ\">B&amp;H<\/a> (advertisement\/affiliate link) for&nbsp;<strong>$1839<\/strong>&nbsp;<\/em><\/p>\n<div dir=\"auto\">\n<h2>Alternatives<\/h2>\n<p>All the alternatives are covered in our <a href=\"https:\/\/phillipreeve.net\/blog\/user-guide-ultra-wideangle-lenses-sony-alpha-7-series\/\">Guide to 9-18mm ultra wide angle lenses<\/a> for E-mount, so I will only talk about the most obvious ones in detail here.<\/p>\n<p><em><strong>A word of caution:<\/strong> it seems to be quite difficult to manufacture these fast ultra wide angle prime lenses as there is a higher degree of sample variation here compared to longer lenses.
