Thanks a lot for the suggestion.
Is the auto focus good in video mode and was also wondering if it's noisy? I was thinking about m43 but there are so many choices that's making it very hard
.No noise whatsoever, the lenses are silent and made with video in mind. The auto focus works very well, with a little lag with the telephoto only, primes are fine though.
The Olympus codec isn't great but the IBIS is amazing and very useful in video. Panasonic has better codec BUT no IBIS so no stabilisation with prime lenses. NEX again is decent but less pancake lenses so as a system imo not as good as M43. Fuji video is crap. Ive used all of them and would recommend Olympus.
Dunno about primes and in lens IS but the GX7 has IBIS.
