I have a possible job coming up just shooting a conversation between 2 people with 2 cameras shooting iso's of each person but the available cameras are only an FX9 and FS5 . Will these cut OK if we shoot UHD Slog 3 on both ? Might have an A7siii as a third camera doing a 2 shot . Of course I guess we could also use the FS5 for the 2 shot - as I know the A7 and FX9 can match. Any experience with that combo?
