Panasonic GH4 Autofocus Speed Found To Be Close to the Nikon D4s

As mirrorless cameras have improved over the years, so to has their autofocusing. Many companies claim that they have the world’s fastest autofocusing capabilities. For years, we’ve stated that Olympus is king in terms of speed but the new Sony A6000 has also really impressed us lately. But the Camera Store decided to put four of the top mirrorless cameras to the test on a dirt bike range. Plus, they also brought along the Nikon D4s.

The cameras put to the test were the Sony A6000, Olympus OMD EM1, Panasonic GH4 and the Fujifilm XT-1 as well as the Nikon D4s. They were all tested with comparable focal lengths at f4. In the end, they conclude that the D4s is still king but that the GH4 is close.

There are problems with the test though:

– At f4, more is in focusing with a Micro Four Thirds sensor than with an APS-C or full frame sensor. They were testing the lenses out at f4

– Panasonic lenses don’t focus as snappily on Olympus cameras and vice versa. This could help account for the findings with the OMD EM1.

– The Sony A6000 was tested with an Alpha adapted lens; not a native E-mount

– The D4s is significantly more expensive.

Despite these flaws in the non-scientific test, it’s still very much worth watching for the insight. Check it out below after the jump. Be also sure to check out our reviews of the Sony A6000, Fujifilm XT1 and the Olympus OMD EM1.
