I am going to be setting up a new reef aquarium and I want to film the process to help people who are getting started in the hobby and I want a camera, I want to buy a camera to film in 4k inside my home with a tripod & slider, i want to do some up close shots of my aquarium and my fish swimming around. My budget is 600-1500$ I was considering the sony a6300 and the sony rx10 ii, but now that I think about it since Im not really going to use it outside portability and size aren't a real issue and thought a larger camera would be cheaper or I could find a better camera for the same price. What would you suggest? I really like being able to shoot in low light and to do closeups of small crustaceans living in my tank but they are 1-2 feet away so I think I would need a telephoto lens. Thanks.
