I mainly shoot live entertainment such as theatre, concerts, and dance. I have been a Canon DSLR shooter for 5 years but I'm transitioning to Sony Mirrorless. I recently bought the a6300 and Zeiss Batis 85mm f/1.8 which I have used for headshots so far. I also bought the 24-70mm f/2.8 GM lens but I might be returning it (still in my 30 day window) because depending on my second body I might not be able to afford it. I am looking at the a7 II, a7S II, and a7R II. What body and lens combo would be recommended to compliment the a6300 and 85 Batis? When I shoot theatre I can usually move freely in the theatre because I'm shooting during dress rehearsals. Concert wise it's either pit or soundboard with the typical 3 songs. If I were to get the 7S II or 7R II I probably wouldn't be able to afford the 24-70mm GM or any other expensive lens to go with the 85 f/1.8 which I have already. Any info would be greatly appreciated!
