and then you can also use the Olympus Ring Flash as a fill-in flash for your portraits.<\/p>\n<p><strong>But before we leave this lens, let&#8217;s look at how it compares with the Canon EF 85mm f\/1.8 lens on a Canon 5D Mark II full frame dSLR:<\/strong><\/p>\n<ul>\n<li><a href=\"http:\/\/www.dxomark.com\/index.php\/Lenses\/Compare-Camera-Lenses\/Compare-lenses\/%28lens1%29\/532\/%28brand%29\/Olympus\/%28camera1%29\/677\/%28lens2%29\/241\/%28brand2%29\/Canon\/%28camera2%29\/176\/%28lens3%29\/241\/%28brand3%29\/Canon\/%28camera3%29\/483#div1anchor\" target=\"_blank\">the Canon lens is sharper at all apertures<\/a> &#8211; partly due to the higher resolution sensor, but even when used on a 5D Mark I it still seems marginally sharper.<\/li>\n<li>the Olympus lens has less distortion and almost half the amount of vignetting wide open and at f\/2.8, but a touch more CA wide open<\/li>\n<li>the Canon lens uses a 58mm filter, and weighs just under 4x as heavy, and 50% longer but is priced at a similar price point<\/li>\n<li>I must admit, my personal experience of the Canon lens seems a lot worse than these tests indicate when looking at the CA levels which to me are quite problematic wide open on the Canon lens.<\/li>\n<li>the Canon lens is an older design which does not have circular aperture blades and thus the Olympus lens should have nicer bokeh stopped down<\/li>\n<li>Olympus lens is optimised for movies and fast contrast detect AF whereas the Canon lens is not.<\/li>\n<li>when used on an Olympus OM-D, you gain 5 stops of 5 axis image stabilisation which is not available for the Canon lens on a Canon camera.<\/li>\n<li>Olympus lens allows faster more accurate AF for slow moving subjects with option of subject eye detection when used on an OM-D or E-P3 or E-PL3 camera.<\/li>\n<\/ul>\n<p>The DxOMark tests on the Canon lens surprisingly beats both the Olympus and the much more expensive Nikkor lens, although it has been known for its sharpness but significant CA.<\/p>\n<p><strong>That said, the Olympus combination of movie capability and 5EV IS along with 1\/5th the weight makes it a compelling choice for travel when compared with either the Canon or the Nikkor lenses.<\/strong><\/p>\n<p>So now we have at least 4 compelling autofocus lens scenarios where Micro Four Thirds competes admirably for even full frame options let alone APS-C dSLR options, and at a much more compact, light and cost effective kit beautifully designed for travel &#8211; I can&#8217;t wait for the Olympus OM-D E-M5 to get to market to make the most of these lenses.<\/p>\n<p>Oh&#8230; the other great autofocus lenses for Micro Four Thirds available now are:<\/p>\n<ul>\n<li><strong>Olympus 12mm f\/2.0<\/strong> wide angle discussed in the <a href=\"http:\/\/www.ayton.id.au\/wp02\/?p=5252\" target=\"_blank\">previous post<\/a><\/li>\n<li><strong>Panasonic 20mm f\/1.7 pancake lens<\/strong> &#8211; the brilliant party lens<\/li>\n<li><strong>Panasonic 25mm f\/1.4 lens<\/strong> &#8211; high quality wide aperture standard lens<\/li>\n<\/ul>\n<p>Coming later this year are the <strong>Olympus 75mm f\/1.8<\/strong> which will be very high on my wish list, the <strong>Olympus 60mm f\/2.8 1:1 macro<\/strong> and the<strong> f\/2.8 zoom lenses from Panasonic<\/strong>.<\/p>\n<p><strong>Very exciting times to be a photographer<\/strong> not wanting to carry around large lenses and cameras, and the lens tests so far show these easily beat the smaller Nikon 1 lenses in terms of image quality, while the larger sensor of the Micro Four Thirds will provide enough ability to blur the background which the Nikon 1 system will struggle to achieve.<\/p>\n<p>Oh, and I don&#8217;t compare it with the tests on a Nikon DX dSLR or a Canon APS-C dSLR as <strong>I just don&#8217;t see much point in owning a cropped sensor dSLR<\/strong> now that Micro Four Thirds cameras AF faster than them with comparable image quality at low ISO, plus you get the 5EV 5 axis IS for any lens when using the Olympus OM-D camera.<\/p>\n<p>But <strong>there are still good reasons to buy full frame dSLR to compliment a Micro Four Thirds kit<\/strong> for those wanting to push the boundaries of shallow DOF, high ISO, or higher dynamic range photography, or for those who need more than 20mp to print larger than 20&#8243; x 30&#8243; prints. Well-heeled Canon full frame dSLR users may want to consider the extremely expensive slow AF but superb <strong>Canon EF 85mm f\/1.2 lens<\/strong> if they really want to push the boundaries.<\/p>\n<p>ps.. Sony NEX users have the option of the <strong>Sony E 50mm f\/1.8 lens<\/strong> but this has not been tested by DxOMark yet and it has a field of view of only a 75mm lens in 35mm camera terms which is quite a bit too short for a portrait lens which historically has been 90-100mm focal length in 35mm terms and it is designed to be a cheap $120 consumer lens. Thus NEX users are out of luck in a true high quality autofocus portrait lens at this stage unless they resort to the much larger Sony alpha lenses.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DxOMark has tested the Micro Four Thirds Olympus 45mm f\/1.8 lens on a Panasonic GH-2 and shows that despite its very compact and light size and sub-$400 price tag, it seems sharper and with less vignetting and distortion wide open than a much more expensive, heavier and larger Nikon AF-S Nikkor 85mm f\/1.4G at f\/1.4 [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23,3],"tags":[44,18,48,14,26],"class_list":["post-5282","post","type-post","status-publish","format-standard","hentry","category-lenses","category-photography","tag-canon","tag-four-thirds-micro","tag-nikon","tag-olympus","tag-portrait"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.8 - aioseo.com -->\n\t<meta name=\"robots\" content=\"max-image-preview:large\" \/>\n\t<meta name=\"author\" content=\"Gary\"\/>\n\t<meta name=\"google-site-verification\" content=\"Dgnw9xhtpcXI39ctj3S_h_tk5whzrsWUy5siHoDRz0M\" \/>\n\t<meta name=\"keywords\" content=\"canon,four thirds micro,nikon,olympus,portrait\" \/>\n\t<link rel=\"canonical\" href=\"https:\/\/www.ayton.id.au\/wp02\/?p=5282\" \/>\n\t<meta name=\"generator\" content=\"All in One SEO (AIOSEO) 4.9.8\" \/>\n\t\t<meta property=\"og:locale\" content=\"en_US\" \/>\n\t\t<meta property=\"og:site_name\" content=\"Gary Ayton photography | Photography news, tips and wikipedia\" \/>\n\t\t<meta property=\"og:type\" content=\"article\" \/>\n\t\t<meta property=\"og:title\" content=\"DxOMark lens tests show the Micro Four Thirds Olympus 45mm f\/1.8 portrait lens seems sharper with less vignetting and distortion than a Nikon 85mm f\/1.4G on a Nikon D700, at 1\/5th the weight and price!!
