This 7Artisans 35mm 1.4 M has no DJ-Optical branding, so I guess it comes from another manufacturer, which makes it more worthwhile to look at potential differences.<br \/>\nThe focus ring has a really nice, high yet even resistance and travels ~100\u00b0 from the minimum focus distance (0.7 m) to infinity. The retail version will also ship with a small rubber focus tab that can be glued to the focus ring.<\/p>\n<p>The aperture ring has full-stop click-stops which is very useful if you count the clicks to know how much you stop the lens down. It travels about 100\u00b0 from f\/1.4 to f\/22.<br \/>\nAt f\/1.4 there is no real distinct click-stop, the ring just hits the end of the scale.<\/p>\n<p>Most parts seem to be made from metal and the markings on focus ring and aperture ring are engraved and filled with paint whereas the branding on the front ring seems to be printed or a glued on sticker.<\/p>\n<p>The lens hood is of the retractable type which is something I find really useful as it takes up no space in the bag and therefore you won&#8217;t be leaving it at home.<br \/>\nIt would have been great if it was matte on the inside instead of shiny though.<\/p>\n<figure id=\"attachment_25731\" aria-describedby=\"caption-attachment-25731\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-25731\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2020\/08\/7Artisans_35m_1.4_M_IF_hood.jpg\" alt=\"7artisans 35mm 1.4 m if internal focus rear m-mount leica m10 sony a7riii a7riv sharpness bokeh resolution contrast review\" width=\"800\" height=\"481\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2020\/08\/7Artisans_35m_1.4_M_IF_hood.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2020\/08\/7Artisans_35m_1.4_M_IF_hood-300x180.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2020\/08\/7Artisans_35m_1.4_M_IF_hood-768x462.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-25731\" class=\"wp-caption-text\">7Artisans 35mm 1.4 M with retractable hood extended<\/figcaption><\/figure>\n<p>There is a small rim on the bayonet, I heard some people like to use this area to paint a 6-bit-coding so it does not wear off when attaching or unattaching the lens, this should also be possible here.<\/p>\n<figure id=\"attachment_25734\" aria-describedby=\"caption-attachment-25734\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-25734\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2020\/08\/7artisans_35mm_1.4_if_m_rear.jpg\" alt=\"7artisans 35mm 1.4 m if internal focus rear m-mount leica m10 sony a7riii a7riv sharpness bokeh resolution contrast review\" width=\"800\" height=\"533\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2020\/08\/7artisans_35mm_1.4_if_m_rear.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2020\/08\/7artisans_35mm_1.4_if_m_rear-300x200.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2020\/08\/7artisans_35mm_1.4_if_m_rear-768x512.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-25734\" class=\"wp-caption-text\">7Artisans 35mm 1.4 M bayonet with rangefinder coupling<\/figcaption><\/figure>\n<p>Even with lens hood retracted the 7Artisans 35mm 1.4 M is a comparably long lens though, this becomes obvious when comparing it to the <a href=\"https:\/\/phillipreeve.net\/blog\/review-voigtlander-vm-35mm-1-2-iii\/\">Voigtlander VM 35mm 1.2 III<\/a> and the <a href=\"https:\/\/phillipreeve.net\/blog\/voigtlander-ultron-11-7-35-mm-review\/\">Voigtlander VM 35mm 1.7<\/a>.<\/p>\n<figure id=\"attachment_25730\" aria-describedby=\"caption-attachment-25730\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-25730 size-full\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2020\/08\/7Artisans_35m_1.4_M_IF_comparison.jpg\" alt=\"7artisans 35mm 1.4 m if internal focus rear m-mount leica m10 sony a7riii a7riv sharpness bokeh resolution contrast review\" width=\"800\" height=\"373\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2020\/08\/7Artisans_35m_1.4_M_IF_comparison.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2020\/08\/7Artisans_35m_1.4_M_IF_comparison-300x140.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2020\/08\/7Artisans_35m_1.4_M_IF_comparison-768x358.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-25730\" class=\"wp-caption-text\">7Artisans 35mm 1.4 M | Voigtlander VM 35mm 1.2 III | Voigtlander VM 35mm 1.7<\/figcaption><\/figure>\n<p>The lens is also part of 7Artisans&#8217; new &#8220;WEN&#8221;-series.

apertures.<br \/>\nNow the 7Artisans 35mm 1.4 M is an internal focus design, therefore I expected better performance here and this is indeed the case.The lens looks good from wide open without any of that softness, have a look at the <a href=\"https:\/\/phillipreeve.net\/blog\/review-ttartisan-35mm-1-4\/#close_070_m_1166\">TTArtisan 35mm 1.4<\/a> for comparison.<\/p>\n<p>So if the wide open

user<\/strong><\/p>\n<p>The 7Artisans 35mm 1.4 M can be considered a bit of a milestone for 7Artisans, as it is their first lens with an internal focus design. This also leads to visibly better performance at wider apertures near the minimum focus distance, but unfortunately the same can not be said about infinity, where the corner resolution never reaches good levels.<br \/>\nThe lens is specifically aimed at streetphotographers, so it may be debatable whether great performance at infinity is something important to that target audience, yet we have seen that other lenses manage to combine compelling rendering with good across frame sharpness, so this should not be an excuse.<br \/>\nNevertheless we should also talk about the bokeh rendering here. At close to mid distances it looks undistracting and compelling to me and the contrast is pretty good from wide open, so the lens seems to follow the Leica design criteria a bit here. At longer focus distances things aren&#8217;t that undistracting anymore, we can sometimes notice field curvature, the effects of optical vignetting and double edged structures and this is true when the lens is used on either, a Sony or a Leica, camera.<\/p>\n<p>I find it a bit hard to wholeheartedly recommend this lens to Sony users, but if you like the rendering or you want to use it at close distances often (e.g. in combination with a <a href=\"https:\/\/phillipreeve.net\/blog\/review-voigtlander-vm-e-close-focus-adapter\/\">helicoid adapter<\/a>) I also have a hard time coming up with a better lens at this size and price point that offers the same specifications.<\/p>\n<div dir=\"auto\">\n<p><strong>M-mount user<\/strong><\/p>\n<figure id=\"attachment_25741\"
