I am looking to upgrade my equipment. I currently shoot with a Sony RX100 II in a Nauticam housing. I shoot 98% underwater video, 1% above water video, and 1% above water pictures. I have wet lenses, Inon uwl-h100 and two stackable Inon ucl-165s. All bayonet mount. I use two L&M Solas and a Kraken Weefine ring light.
I want the ability to change lenses and shoot sharks and nudis on the same dive. Does this sound feasible for the GH5? What camera body lens would I need? Is this worth the bang for the buck or would I be better off sticking with a new Sony RX100 V? All the videos shot are just for my own memories.
