I don't know if i'm the only one who thinks this way or if my thinking is all wrong but..the way i look at FF is, if you want to go FF, go for the best in its class.
So in this case, either the 5D3 or 1DX or even 5D2.
The 6D to me should be a secondary FF camera to compliment what you should already own, i don't think it should be your one and only camera. Simply because although it's FF, it is hindered by some other "lower" specs like the AF points.
Why should one compromise specs that are important just to go FF.
Maybe it's just me, but i never ever did look at the 6D as a primary camera
So you honestly think the AF of the 5D2 is better then the 6D's?
Why should someone need the 5D3's AF (or even 1DX) if he doesn't do sports?
Btw you are the first one who reported that the outer AF-Points are crap (what I read.. I'm sure I haven't read all reports out there
Oh and how can the 5D2 at 3.9fps be faster than the 6D at 4.5fps?
