While many of the competitors often cut corners with their compact lenses when it comes to build quality, feature set and sometimes also optical quality, Sony decided to go for a different approach here, offering more, but also at a higher price point. Did that pay off?

If you are used to other (higher end) Sony lenses this is very nice as you will feel right at home.<\/p>\n<p>The focus ring has a very nice and even resistance. It takes exactly 180\u00b0 from the minimum focus distance of 0.28 m to infinity and the coupling is linear.<\/p>\n<p>In the marketing material Sony also shows some pictures without the paint where you can see that the outer casing is actually made of metal.<\/p>\n<figure id=\"attachment_58328\" aria-describedby=\"caption-attachment-58328\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-58328\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2024\/07\/Sony_FE_40mm_2.5_G_left.jpg\" alt=\"fe 40mm 2.5g 2.5 g sony 42mp 61mp a7rii a7riv a7riii a1 a9iii a7rv review resolution sharpness contrast bokeh vignetting coma\" width=\"800\" height=\"533\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2024\/07\/Sony_FE_40mm_2.5_G_left.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2024\/07\/Sony_FE_40mm_2.5_G_left-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2024\/07\/Sony_FE_40mm_2.5_G_left-768x512.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-58328\" class=\"wp-caption-text\">lens button and AF\/MF switch<\/figcaption><\/figure>\n<p>On the left side you can find a lens button and an AF\/MF switch.<\/p>\n<figure id=\"attachment_58329\" aria-describedby=\"caption-attachment-58329\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-58329\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2024\/07\/Sony_FE_40mm_2.5_G_right.jpg\" alt=\"fe 40mm 2.5g 2.5 g sony 42mp 61mp a7rii a7riv a7riii a1 a9iii a7rv review resolution sharpness contrast bokeh vignetting coma\" width=\"800\" height=\"533\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2024\/07\/Sony_FE_40mm_2.5_G_right.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2024\/07\/Sony_FE_40mm_2.5_G_right-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2024\/07\/Sony_FE_40mm_2.5_G_right-768x512.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-58329\" class=\"wp-caption-text\">aperture de-click lever<\/figcaption><\/figure>\n<p>At the bottom there is also a de-click lever for the aperture ring to be found.<\/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-sony-fe-40mm-2-5-g-41363\"><li class=\"active\"><a href=\"#ert_pane1-0\" data-toggle=\"tab\">40mm 2.5 hood<\/a><\/li><li class=\"\"><a href=\"#ert_pane1-1\" data-toggle=\"tab\">24mm 2.8 hood<\/a><\/li><\/ul><\/div><div style=\"clear:both;width: 100%;\"><ul class=\"tab-content\" id=\"oscitas-restabcontent-1-review-sony-fe-40mm-2-5-g-41363\"><li class=\"tab-pane active\" id=\"ert_pane1-0\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-58327\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2024\/07\/Sony_FE_40mm_2.5_G_Hood_40.jpg\" alt=\"fe 40mm 2.5g 2.5 g sony 42mp 61mp a7rii a7riv a7riii a1 a9iii a7rv review resolution sharpness contrast bokeh vignetting coma\" width=\"800\" height=\"533\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2024\/07\/Sony_FE_40mm_2.5_G_Hood_40.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2024\/07\/Sony_FE_40mm_2.5_G_Hood_40-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2024\/07\/Sony_FE_40mm_2.5_G_Hood_40-768x512.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-58326\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2024\/07\/Sony_FE_40mm_2.5_G_Hood_24.jpg\" alt=\"fe 40mm 2.5g 2.5 g sony 42mp 61mp a7rii a7riv a7riii a1 a9iii a7rv review resolution sharpness contrast bokeh vignetting coma\" width=\"800\" height=\"533\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2024\/07\/Sony_FE_40mm_2.5_G_Hood_24.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2024\/07\/Sony_FE_40mm_2.5_G_Hood_24-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2024\/07\/Sony_FE_40mm_2.5_G_Hood_24-768x512.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/li><\/ul><\/div><\/div><span style=\"color: #999999;\"><i>Sony FE 40mm 2.5 G with different lens hoods<\/i><\/span><\/p>\n<p>This Sony FE 40mm 2.5 G ships with an interesting looking lens hood, which I am sure offers great protection, but won&#8217;t win any prizes for great design.

For me the stand out features are the compact size coupled with very high resolution and contrast from f\/2.5 as well as the non-existent field curvature. The latter being an area where many compact lenses struggle.<\/p>\n<p>I also really like that Sony decided to give this lens the full feature set of a higher end lens, something other manufacturers often like to cheap out on with their compact lenses.<\/p>\n<p>What surprised me a bit is that the CA correction and flare resistance aren&#8217;t that great, but then the vignetting is actually lower than I would have expected and in the end there is no really outstanding flaw with this lens.<\/p>\n<p>If you are in the market for a compact 40mm lens and you don&#8217;t need a maximum aperture faster than f\/2.5, you can hardly go wrong with this one.<\/p>\n<p><em>buy from <a href=\"https:\/\/amzn.to\/3HdrISX\">Amazon.com<\/a> | <a href=\"https:\/\/amzn.to\/3EwX84T\">Amazon.de<\/a> | <a href=\"https:\/\/bhpho.to\/3szhcRN\">B&amp;H<\/a> | <a href=\"https:\/\/www.ebay.com\/sch\/i.html?_from=R40&amp;_trksid=p2334524.m570.l1313&amp;_nkw=sony+40mm+2.5&amp;_sacat=0&amp;LH_TitleDesc=0&amp;_odkw=sigma+105+dg+dn&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> (advertisement\/affiliate links) for <strong>$548<\/strong><\/em><\/p>\n<h2>Alternatives<\/h2>\n<p>You can find most of the alternatives in our <a href=\"https:\/\/phillipreeve.net\/blog\/fe-lenses-sony-comprehensive-independent-guide\/\">Sony FE Guide<\/a>. The closest competitors are probably the <a href=\"https:\/\/phillipreeve.net\/blog\/review-carl-zeiss-sonnar-fe-2-835-za-t\/\">Sony FE 35mm 2.8 ZA<\/a>, <a href=\"https:\/\/phillipreeve.net\/blog\/review-zeiss-batis-2-40-cf\/\">Zeiss Batis 40mm 2.0 CF<\/a>, the Sigma 45mm 2.8 C DG DN or the Samyang FE 45mm 1.8 AF. Honestly, if I had to pick among these, I would probably go for this Sony FE 40mm 2.5 G, as all the others have at least one flaw that sticks out a bit.<\/p>\n<p>The more important question is, if you wouldn&#8217;t be better off with one of the compact f\/2.8 zoom lenses. There is e.g. the Sony FE 24-50mm 2.8 G which offers the same feature set, but covers the range of all three of Sony&#8217;s compact G lenses. It is more expensive than one lens, but as soon as you buy two of them the difference ain&#8217;t that big anymore. So if you are thinking of getting a wide angle lens in addition to this 40mm and\/or you always carry more than one lens anyway, I think the zoom would be the better choice for you as you would be more flexible while not really carrying noticeably more weight or having spent more money.<\/p>\n<h2>Sample Images<\/h2>\n<figure id=\"attachment_58001\" aria-describedby=\"caption-attachment-58001\"
