Which A7 MkII body and lenses to purchase for concert/theatre photography

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!

 

Yeah I still have my Canon glass for the moment. I was planning on selling it to help pay for the new Sony gear lol. I might have to look into that though, thanks! How does the A7 II perform for theatre? Do you think the A7S II is better suited due to its low light capability?

 

Luckily for me any concert or theatre I shoot the lighting is at the worst decent so I might not need the A7S II. Is the A7 II good at auto focusing in lower light? I read the original A7 was pretty bad so I didn't know if it got better with the MK II? The a6300 is good at continuous burst so I really don't need two bodies that are good with that.

 

I only have one Canon lens. The other two are Sigma and Tamron for Canon mounts. So obviously I would get the Metabones IV to cover both my Canon and Sigma glass. What about Tamron lenses? Say I decide not to use my Canon mount lenses and go with something to compliment my Zeiss 85 f/1.8 Batis. Would you recommend the A7Rii still over the A7Sii and A7ii? What about lenses?

 

Thanks! The Sigma lenses you mentioned aren't e mount lenses, right? I would need to get the Metabones IV? What about the A7ii with native lenses? Would it be better than the A7rii with adapted lenses?

 

Thanks for the info! I think I'd rather shoot with native lenses because I like the eye AF etc.

 

That's good to know, thanks!
