Just saw that Panasonic released new firmware for GH4. v2.0 firmware!

New firmware is available from:

: 4K PHOTO mode added which records 4K video exclusively for capturing a frame to save as a photo. In addition to 16:9 aspect, 4:3/3:2/1:1 can be selected.
: Exif information is embedded to the captured image from the 4K video.

: Marking function was added which allows you to insert marker setting at the designated point while recording video. This allows the user to jump to the markers when playing back the video to capture the frame they want.

:Loop Recording function was added, with which the camera keeps on recording video while deleting the old footage automatically.

: 4K/23.98p/100Mbps mode is added in MP4 video recording.
: The upper limit of the ISO sensitivity can be set in the menu of ISO sensitivity setting and the photo flash output can now be adjusted in the menu of exposure compensation.

: Focusing performance of 1-area AF in video recording is improved.

: Tracking performance of tracking AF when used with the interchangeable lens H-FS14140 is improved.

: Remote shooting via USB tethering is available by using PC software "USB Tether" supplied by Promote Systems.
Windows version available now, with Mac version available soon.

: Version 2.0 also gives you compatibility to Promote’s USB controller

I don't know if it was doing that before but I found out that when I'm controlling the GH4 with my Android Phone, the Constant AF is not working. I have to touch to refocus. Not sure if it was like that before the firmware update. Can anyone try this please?

-AF in 4k with 14-140 II is faster and more accurate.
-4k and fullhd 100Mbs bitrates have increased from about 75-80Mbs to 97Mbs (not documented but I tested)
