The answer is <strong>yes<\/strong>.<\/p>\n<p>Canon&#8217;s EF mount is one of the most popular lens mounts out there. Canon&#8217;s own lenses are well-respected, as are lenses from a wide range of third-party manufacturers that build lenses for the EF mount such as Sigma, Tokina, and Zeiss.<\/p>\n<p>If you&#8217;re coming to the Panasonic GH4 from a Canon 5DMKIII, Canon 7D, or any other camera with Canon&#8217;s EF mount, it&#8217;s no surprise that you would want to keep using your EF lenses on the GH4.<\/p>\n<p>Like most other lens mounts, Canon&#8217;s EF mount is compatible with the GH4&#8217;s versatile Micro Four Thirds (MFT) mount with the aid of a lens adapter.<\/p>\n<p>However, as Canon&#8217;s EF lenses are electronically controlled, <em>mounting<\/em> the lens is only half the story. Using most Canon EF lenses effectively also requires the adapter to <strong>communicate<\/strong> with the lens.<\/p>\n<p>In other words, you may need an <em>active<\/em> adapter.<\/p>\n<h2>Active Lens Adapters<\/h2>\n<p>Most Canon EF mount lenses do not feature a manual aperture ring. These lenses require an <em>active<\/em> lens adapter to adjust aperture.<\/p>\n<p>An active adapter has electronic contacts that allow the adapter to communicate with the lens, letting you control things like aperture.<\/p>\n<p><a href=\"https:\/\/suggestionofmotion.com\/wp-content\/uploads\/Metabones_Adapter_Canon-EF-MFT-QTR.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-3161\" src=\"https:\/\/suggestionofmotion.com\/wp-content\/uploads\/Metabones_Adapter_Canon-EF-MFT-QTR-693x699.jpg\" alt=\"Metabones Canon EF Smart Adapter\" width=\"693\" height=\"699\" srcset=\"https:\/\/suggestionofmotion.com\/wp-content\/uploads\/Metabones_Adapter_Canon-EF-MFT-QTR-693x699.jpg 693w, https:\/\/suggestionofmotion.com\/wp-content\/uploads\/Metabones_Adapter_Canon-EF-MFT-QTR-336x339.jpg 336w, https:\/\/suggestionofmotion.com\/wp-content\/uploads\/Metabones_Adapter_Canon-EF-MFT-QTR-607x612.jpg 607w, https:\/\/suggestionofmotion.com\/wp-content\/uploads\/Metabones_Adapter_Canon-EF-MFT-QTR.jpg 720w\" sizes=\"(max-width: 693px) 100vw, 693px\" \/><\/a><\/p>\n<p>Here are the current active adapter options:<\/p>\n<h2>Metabones Speed Booster<\/h2>\n<p>The Metabones Speed Booster is a well-regarded lens adapter available for many different lens mounts.

The lens will mount to the adapter just fine and you can use it on the GH4. The key difference is that you won&#8217;t be able to adjust the aperture.<\/p>\n<p>The key thing is to be aware of the effects that losing aperture control will have:<\/p>\n<h3>Sharpness<\/h3>\n<p>Some lenses are soft wide open, other&#8217;s are nice and sharp. When you have aperture control, you can stop down the aperture to improve sharpness. However, if you&#8217;re happy with your lens&#8217; sharpness wide open, then slap on a passive adapter and shoot!<\/p>\n<h3>Exposure Control<\/h3>\n<p>Aperture is one way to control exposure on a camera. Without aperture control, you will only be able to adjust exposure using shutter speed and ISO.<\/p>\n<p>If the image is still overexposed when you&#8217;ve adjusted shutter speed and ISO as much as possible, you can use <abbr title=\"Neutral Density\">ND<\/abbr> filters in front of the lens to dial in the desired exposure.<\/p>\n<h3>DOF Control<\/h3>\n<p>A wide open aperture means the lens is stuck at it&#8217;s shallowest depth of field (DOF). This may make focusing more difficult&#8211; especially for fast lenses (e.g. f\/1.2)&#8211; but if a shallow DOF is a good fit for your project, then you would need to deal with that anyway.<\/p>\n<div class=\"highlight\">\n<p><strong>Bottom line:<\/strong> If you&#8217;re fine with shooting wide open and using <abbr title=\"Neutral Density\">ND<\/abbr> filters to control exposure, grab yourself an inexpensive passive adapter and have fun!<\/p>\n<\/div>\n<div class=\"cta\">\n<h2>Free Consult<\/h2>\n<p> Are you excited about the potential of the Panasonic GH4 and its versatile Micro Four Thirds lens mount, but feel overwhelmed by all the options?<\/p>\n<p>The Panasonic GH4&#8217;s MFT system may be completely new territory for a many of you.
