Hi Kandinsky, thanks for thr link. Very informative. Have not gone around to matching profiles and shots yet. That will be on my list.
On a side note. Tried the canon 70d afc in video and was very impressed. Easily as good as GH4. But GH4 has one extra pattern tracking mode which i find it more useful than face recognition tracking. You can track a subject with a nice printed shirt effortlessly.
Becareful of the GH3/GH4 Auto Focusing for video.
Sometimes they have a very very minor incremental focusing 'jerk' when focusing from between a 0.3 metres object to an object 50 metres away.
The problem is that its very very minor and cannot be seen on the LCD. Only when u blow it up on your 27 inch screen then u see it.
