I could not find any official information on who manufactures these lenses in Korea, but I did find some circumstantial evidence pointing at Samyang, which does make a lot of sense actually.<\/p>\n<p>These Irix lenses are purely manual focus lenses but they do feature electronic contacts to communicate with the camera.<\/p>\n<p>Earlier Irix lenses came in two versions, &#8220;Firefly&#8221; (a bit cheaper and ligther thanks to using more polycarbonate) and &#8220;Blackstone&#8221; (a bit more expensive and heavier thanks to more metal). The optics were the same and I always wondered if it actually makes sense to have these two series, because the differences in price and weight actually weren&#8217;t that big. As later Irix lenses only come in one version titled &#8220;Dragonfly&#8221;, maybe the people behind Irix had the same thoughts after all.<\/p>\n<p>Most Irix lenses are internal focus lenses. The focus ring of this 45mm 1.4 rotates ~180\u00b0 fromt he minimum focus distance of 0.4 m to infinity &#8211; a solid choice. The focus ring is rubberized and as was already the case for the Zeiss Milvus\/Otus\/Batis and Samyang XP lenses that rubber is really good at attracting dust and other debris. The resistance is nice and even though.<\/p>\n<p>At the front of the lens there is also a focus lock ring. It can be useful e.g. for astrophotography so that you won&#8217;t accidentally change your focus setting. It doesn&#8217;t lock super tight though, when using a litte more force you will still be able to adjust the focus setting, even when the ring has been fully locked.<\/p>\n<figure id=\"attachment_71310\" aria-describedby=\"caption-attachment-71310\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-71310\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/04\/Irix_45mm_1.4_Dragonfly_Hood.jpg\" alt=\"irix 45mm 1.4 dragonfly firefly blackstone south korea 42mp 61mp 24mp z6 z7 z8 z9 a7iv a7v a7riv a7riii a7r2 a7 a9 a1 review contrast resolution bokeh vignetting coma ca loca sunstars distortion\" width=\"800\" height=\"533\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/04\/Irix_45mm_1.4_Dragonfly_Hood.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/04\/Irix_45mm_1.4_Dragonfly_Hood-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2025\/04\/Irix_45mm_1.4_Dragonfly_Hood-768x512.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-71310\" class=\"wp-caption-text\">Irix 45mm 1.4 Dragonfly with hood attached<\/figcaption><\/figure>\n<p>A lens hood which can be mounted reversed is also part of the package.

With manufacturers like Samyang and Viltrox offering more compact affordable AF options these days, many of those big manual focus DSLR lenses have simply become undesirable relics of the past by now.<\/p>\n<p>Some of them bring something to the table that you cannot easily find with the latest designs though and this Irix 45mm 1.4 Dragonfly is one such case, as with its undercorrected spherical aberration it creates a very appealing out of focus rendering similar to lenses like the <a href=\"https:\/\/phillipreeve.net\/blog\/review-nikon-af-s-58mm-1-4g-better-than-its-reputation\/\">Nikon AF-S 58mm 1.4G<\/a> or <a href=\"https:\/\/phillipreeve.net\/blog\/review-sony-fe-85mm-1-4-gm\/\">Sony FE 85mm 1.4 GM<\/a>.<\/p>\n<p>As you can find it at bargain prices these days, this Irix 45mm 1.4 Dragonfly can still be a desirable tool for portrait photographers &#8211; even if just used for special occasions due to its somewhat unpleasant size and weight.<\/p>\n<p><em>buy from <a href=\"https:\/\/amzn.to\/3RMDLOp\">amazon.de<\/a> | <a href=\"https:\/\/bhpho.to\/433sa2F\">B&amp;H<\/a> | <a href=\"https:\/\/www.ebay.com\/sch\/i.html?_nkw=irix+45mm+1.4&amp;_sacat=0&amp;_from=R40&amp;_trksid=p4432023.m570.l1313&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?_nkw=irix+45mm+1.4&amp;_sacat=0&amp;_from=R40&amp;_trksid=p4432023.m570.l1313&amp;mkcid=1&amp;mkrid=707-53477-19255-0&amp;siteid=77&amp;campid=5337820268&amp;toolid=20008&amp;mkevt=1\">ebay.de<\/a> (<i>advertisement\/<\/i>affiliate links) for <strong>$379<\/strong><\/em><\/p>\n<h2 dir=\"auto\">Alternatives<\/h2>\n<div dir=\"auto\">\n<h3>DSLR designs<\/h3>\n<p><a href=\"https:\/\/phillipreeve.net\/blog\/review-sigma-40mm-1-4-art\/\"><em><strong>Sigma 40mm 1.4 Art:<\/strong><\/em><\/a><br \/>\nOne of the few higher end DSLR lenses with a focal length between 35 and 50mm.
