Ok guys and gals, I could really use your input. I am upgrading to a full frame camera for my wedding photography and I could use some input. Since I launched my wedding business this year I already have 4 wedding booked. I just sold my Canon 7d and I am about to purchase a full frame camera so that I don't have to keep renting one. I do not want to go in debt since my business is in its infancy. The three cameras that I am looking at in my price range are the Canon 6D, Nikon D800, and the Sony A7ii. The two that I am really looking at is the Nikon d800 and the Sony A7ii. I am really leaning towards the Sony but I know it has its drawbacks and weaknesses. If any one has any experience with these cameras please let me know your thoughts.
Go with the Sony! I had a D800 and it does not, repeat, does NOT, focus well in low light. It is an ok studio camera, but a lousy, that is LOUSY, event camera. I shoot two D750 bodies now. They're great cameras.
