The Panasonic GH4 has been the gold standard for m43 video for a while now, but the IBIS in the GX85 makes it a far better value for videographers until the Panasonic GH5 comes out. Both cameras have very similar video quality and were locked together using a Fhugen cage using the Panasonic 25mm f1.7 lens at ISO 400 1/50th shutter speed. I would imagine the new Panasonic G85 performs similarly or better than the GX85. It seem the GH4 could use a price drop before the GH5 come out.
