Cristian Mihai: BE AWARE PEOPLE OF LUMIX GX7This camera has the mini HDMI port locked! You cannot use the HDMI port for LIVE work. Only playback mode ! Their website says mini HDMI output but it hides the fact it's locked! FALSE ADVERTISING
IIRC, HDMI work in same way for every panasonic m43 camera, isn't it? HDMI only for PLAY, and analog output works for LIVE and PLAY. Just checked with my old GF2.
ProfHankD: Good for Eye-Fi... BUT the Transcend has been hacked, so it is possible (easy) to get access to it as a little Linux system with all the programmability that implies: http://haxit.blogspot.ch/2013/08/hacking-transcend-wifi-sd-cards.html
I haven't tested the Transcend yet, but I'm looking forward to running my own scripts in it. ;-) Incidentally, I've been using an Eye-Fi card for a couple of years to do live continuous downloads of a camera at a research exhibit, and it is good even talking to Linux (not officially supported), but has serious trouble dealing with heavily-loaded wi-fi situations (i.e., a computing conference exhibit floor).
Another thing - openwrt guys working on port for transend card...
