Hey, looking for upgrading my GH4 - currently selling my whole set (gh4,lenses,recorder) and for a two weeks looking for upgrade so 1, Sony FS5 (my number one) but only 50mbps in 4k / no 4k 10bit via SDI/HDMI - possible fw upgrade, fhd is all good 2, BM Ursa mini (no so many info/rev here) black sun spot again, cannot use with my ronin-m 3, A7sII (sooo small) fx but same specs for 4k and i think not worth to upgrade from GH4 right ? So i am pretty lost now, looks like its not extra-worthy to upgrade from GH4 now BUT what could be better ? i'd love to hear someone who upgraded from GH4 too, thanks
