The focus ring has a nice, well dampened resistance and turns about 90\u00b0 from the minimum focus distance (1.0 m) to infinity. There is not only a hard-stop, there is also an infinity lock, so if your lens is set to infinity you first have to push down the button on the focus tab to be able to change the focus distance.<\/p>\n<figure id=\"attachment_30127\" aria-describedby=\"caption-attachment-30127\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-30127\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2021\/11\/TTArtisan_28mm_5.6_infinity_lock.jpg\" alt=\"ttartisan 28mm 5.6 m m-mount pancake review smallest leica contrast sharpness resolution\" width=\"800\" height=\"450\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2021\/11\/TTArtisan_28mm_5.6_infinity_lock.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2021\/11\/TTArtisan_28mm_5.6_infinity_lock-300x169.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2021\/11\/TTArtisan_28mm_5.6_infinity_lock-768x432.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-30127\" class=\"wp-caption-text\">Focus tab with infinity lock<\/figcaption><\/figure>\n<p>Now me personally, I neither like that infinity focus lock &#8211; which slows me down a lot during shooting &#8211; nor a minimum focus distance of 1.0 m &#8211; which is very long even for a rangefinder lens.<\/p>\n<p>The aperture ring has full-stop click stops and turns roughly 30\u00b0 from f\/5.6 to f\/22.<\/p>\n<p>The lens is rangefinder coupled across the whole distance range and considering its specifications I don&#8217;t expect any calibration issues.

Under overcast skies I often had to push the ISO a bit to get a shutter speed of 1\/30s and things obviously got worse in the evening or indoors.<\/p>\n<p>I think you know everything there is to know now to figure out if this lens is for you.<\/p>\n<figure id=\"attachment_30124\" aria-describedby=\"caption-attachment-30124\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-30124\" src=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2021\/11\/TTArtisan_28mm_5.6_A7rII.jpg\" alt=\"ttartisan 28mm 5.6 m m-mount pancake review smallest leica contrast sharpness resolution\" width=\"800\" height=\"450\" srcset=\"https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2021\/11\/TTArtisan_28mm_5.6_A7rII.jpg 800w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2021\/11\/TTArtisan_28mm_5.6_A7rII-300x169.jpg 300w, https:\/\/phillipreeve.net\/blog\/wp-content\/uploads\/2021\/11\/TTArtisan_28mm_5.6_A7rII-768x432.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-30124\" class=\"wp-caption-text\">TTArtisan 28mm 5.6 via TTArtisan M-&gt;E adapter on Sony A7rII<\/figcaption><\/figure>\n<\/div>\n<p><em>The lens can already be preordered from the <a href=\"https:\/\/ttartisan.myshopify.com\/products\/m-28mm-f5-6?ref=EvdGAnf950qaM\">manufacturer&#8217;s shop<\/a> and <a href=\"https:\/\/bhpho.to\/3EeY25U\">B&amp;H<\/a> (affiliate link) and the price is <strong>$298<\/strong><\/em><\/p>\n<h2>Alternatives<\/h2>\n<p><strong>Leica 28mm 5.6 Summaron-M:<\/strong><br \/>\nThe Leica lens looks almost exactly the same from the outside, but the optics are completely different.
