Anamorphic Adapter
 

I am shooting a short film in a few months with an FS7, and the filmmakers would like me to shoot anamorphic. I was wondering what the best setup for the FS7 would be. I will be shooting in 4K 17:9 (XAVC I), using Sony primes, and I didn't know if that affected what adapter I should use.

Any suggestion or help on this would be greatly appreciated.
