New GH4 test by EosHD and Focus Numerique.

EOSHD GH4 vs GH3 rolling shutter train test from Andrew Reid on Vimeo.

We have a couple of new GH4 tests:

Panasonic GH4  Slow-mo at 96fps and 4K rolling shutter test at EosHD:

Panasonic have made great efforts to speed up the sensor in the GH4 so in slow-mo at 96p and standard 1080/60/50p the GH4 has less rolling shutter than the GH3 thanks to a 50% faster sensor readout.
In 4K mode the sensor has to readout 4x the amount of data than in 1080p and the 50% increase in readout speed isn’t enough to compensate.
The result is that in 4K the GH4 has slightly worse rolling shutter than the GH3 in 1080p.

Focus Numerique (google translation here) tested the GH4 High ISO quality:

On the 100-800 ISO range, the images of GH4 are superb with a nice dynamic and bold colors. Only at ISO 800 the finer details (100% on-screen display) are slightly faded. Nothing so dramatic. At 3200 ISO, the GH4 provides the first signs of weakness with greater noise and greater detail and dynamics loss. Again, the images are usable, but beyond this sensitivity, the damage will be greater.
