What do you guys think about the Sony A7ii ? I have used the Sony Nex 5 for a while and love it, because it's compact. Now i want to take it all to the next step and get a full frame camera. I was pondering about a Canon or Nikon, but i already have a Sigma Lens that would only go on a E mount of a Sony and i'm not sure it would be compatible with an other brand.
Mostly i wanna do portraits, architechture and landscapes. Not really interested by video although if i ever need it, can be nice to have a great quality.
