Rotate that ring to adjust the focus of your lens until the image is sharp through the viewfinder, and then you can take a shot. On some lenses, adjusting the focus ring can change the angle and magnification of your subject. This can make things <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>ear closer to or farther away from you depending on whether they\u2019re in focus. Focus breathing, also called lens breathing, is that change in apparent focal length.<\/p>\n<p>When this happens, it looks like the image you see through the viewfinder is \u201cbreathing,\u201d hence the name. Focus breathing can happen on a zoom lens or a prime lens (a lens with a fixed length, like 50mm), and will always cause an apparent decrease in focal length, not an increase. In other words, it will seem like you\u2019re viewing things at a slightly wider angle. Check out <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.youtube.com\/watch?v=bIrJUFtYxiQ\">an example video<\/a> uploaded by\u00a0HDSLR35 Online Filmschool for a demonstration.<\/p>\n<p>Put another way, it will look like your lens is zooming slightly in and out as you adjust focus, even if it\u2019s a fixed length. In most lenses, this change is so small that it doesn\u2019t make a difference to the final image, especially since it only takes place at close focusing distances. Certain lenses, however, can have significant issues with focus breathing that make them challenging to use.<\/p>\n<p>Photographers won\u2019t notice lens breathing much unless they\u2019re trying to take several images at different focal points to stitch them together for a more detailed shot (a technique called focus stacking). Where it causes more of a problem is videography \u2014 if the frame is constantly zooming when the focus changes, it distracts the viewer and takes them out of the narrative you\u2019re trying to create.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Why_Lenses_%E2%80%9CBreathe%E2%80%9D\"><\/span>Why Lenses \u201cBreathe\u201d<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Camera lenses each have multiple glass lenses inside them to direct and focus light. These glass pieces are built together in groups called lens elements or just \u201celements.\u201d This design makes it easier, faster, and quieter to focus a lens, particularly if it has an autofocus motor. It also means that the mechanism for focusing your lens is entirely inside the lens barrel.<\/p>\n<figure style=\"width: 650px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-780920 size-full\" data-pagespeed-lazy-src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2022\/01\/camera-lens-anatomy.jpg?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"A camera lens assembly cut across the diameter to expose the anatomy.\" width=\"650\" height=\"446\" data-crediturl=\"https:\/\/www.shutterstock.com\/image-photo\/anatomy-camera-lens-isolated-white-background-14849464\" data-credittext=\"yuyangc\/Shutterstock.com\" src=\"\/pagespeed_static\/1.JiBnMqyl6S.gif\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><figcaption class=\"wp-caption-text\"><span class=\"imagecredit\"><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.shutterstock.com\/image-photo\/anatomy-camera-lens-isolated-white-background-14849464\">yuyangc\/Shutterstock.com<\/a><\/span><\/figcaption><\/figure>\n<p>Unless you\u2019re using a zoom lens, the outside part of the lens won\u2019t move when you adjust focus. Instead, some of the internal glass elements move while others remain stationary. The change in distance as this movement happens is what produces the lens breathing effect.<\/p>\n<p>Manufacturers today make lenses that can mostly correct for this, so you\u2019ll notice very little focus breathing on many later models compared to their older counterparts.<\/p>\n<p><strong>RELATED:<\/strong> <strong><em>Why Are Good Camera Lenses So Important?<\/em><\/strong><\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"How_to_Check_a_Lens_For_Focus_Breathing\"><\/span>How to Check a Lens For Focus Breathing<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Checking that lens you\u2019re about to buy for excessive focus breathing is pretty simple if you have it in front of you. Just attach the lens to your camera, put your camera on a <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/trip-and-travel\/\" data-internallinksmanager029f6b8e52c=\"10\" title=\"Trip &amp; Travel\" target=\"_blank\" rel=\"noopener\">trip<\/a>od, and adjust the focus ring from close focus to infinity. A very slight zoom effect is normal, but if you notice a lot of zooming in and out as you change focus, you may want to pick a different lens.<\/p>\n<p>If you\u2019re looking at the specs online, look for the \u201cmaximum magnification\u201d number. You might also see it written as \u201cmaximum reproduction ratio\u201d or \u201creproduction ratio.\u201d The higher that number is, the less focus breathing the lens will have.<\/p>\n<p>So is focus breathing something you should worry about? Not really. Modern lenses have focus breathing correction built in, and once you learn to compensate for it, you probably won\u2019t even notice it anymore.<\/p>\n<p>For a lengthier and more technical breakdown of focus breathing, check out <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/photographylife.com\/focus-breathing\">this article<\/a> by Photography Life.
