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.
The FX3a model introduced May 7, 2025 differs in only one aspect: the Rear LCD has been upgraded.
