Of course, the Olympus E-M5 Mark II has the built-in 5-axis image stabilization on the image sensor itself. The Panasonic GH4 is tested with lens-based image stabilization using the Panasonic Lumix G X Vario 12-35mm f/2.8 APSH. POWER OIS lens.
The E-M5 Mark II performs extremely well in the overall stabilization throughout the video sample. Whereas the Panasonic 12-35mm lens just falls apart in its efforts at certain points. The 5-axis stabilization in the Olympus camera looks like a real hit in this revealing comparison.
The source criticizes the sharpness of the E-M5 Mark II frames in comparison to the Panasonic GH4; however, that’s a tough call to make since the video was shot with both cameras in Program mode, so the shutter speed seems to be obviously faster in the examples provided.
Still, it’s a nice comparison of two cameras in a side-by-side handheld environment. Other features of the cameras may push potential buyers in a different direction (e.g., the ability to record 4K video), but it is pretty clear than the E-M5 Mark II kicks butt at handheld video.
