Sony FX3

bythom sony fx3

The FX3 is basically an A7S Mark III, but designed into a more compact body that is solely oriented towards video. Normally I don't cover the Sony Pro video cameras on this site, but I've made an exception in this case, as many will want to select between an A7S Mark III and FX3.
