The main reference point that people therefore use is the 35mm one which is considered &#8216;full frame&#8217; size.\n<\/p>\n<p>\nIf you compare the size of the film in a normal SLR (film is 35mm) to the image sensor in most DSLRs you&#8217;ll find that the size of the DSLRs sensor is generally smaller (unless you get what&#8217;s called a &#8216;full frame&#8217; DSLR).\n<\/p>\n<p>\nUntil recently &#8216;full frame&#8217; cameras were largely in the realm of professional DSLRs and all lower end cameras had smaller sensors.\n<\/p>\n<p>\nIf you take a photo with a smaller sensor and the same lens it will only show a smaller area of the scene.\n<\/p>\n<p>\nTo illustrate this I&#8217;ve show how different cameras with different image sizes will see an image.\n<\/p>\n<p>\n<span class=\"responsive-image \" style=\"width:450px\"><span class=\"space\" style=\"width:450px; padding-top:65.78%\"><\/span><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/digital-photography-school.com\/wp-content\/uploads\/2007\/03\/crop-factor.jpg?resize=450%2C296&#038;ssl=1\" height=\"296\" width=\"450\" border=\"0\" hspace=\"10\" vspace=\"10\" alt=\"Crop-Factor\" \/><\/span>\n<\/p>\n<p>\n<!--more--><br \/>\nFinding this helpful? <a rel=\"nofollow noopener\"  href=\"http:\/\/digg.com\/design\/Crop_Factor_Explained\">Digg This Post<\/a><\/p>\n<p><strong>Black<\/strong> &#8211; Full Frame<br \/>\n<span style=\"color:#ff0000;\">Red<\/span> &#8211; 1.3x Crop Factor<br \/>\n<span style=\"color:#e0e201;\">Yellow<\/span> &#8211; 1.5x Crop Factor<br \/>\n<span style=\"color:#00ff00;\">Green<\/span> &#8211; 1.6x Crop Factor\n<\/p>\n<p>\nWhen you enlarge images to the same size from different  sensors the ones with the smaller sensors will be enlarged more &#8211; making it seem bigger.\n<\/p>\n<p>\nAs a result &#8211; when you fit a lens to a camera with a smaller sensor the lens is often said to have a larger equivalent lens size.\n<\/p>\n<p><!--adsense--><\/p>\n<p>\nI&#8217;ve included a table below that shows the equivalent lens sizes for different crop factors.
