but this happen to the d600 too
they did start to bring the full fram to everyone or at least to a cheap price
the point is that i would like to have a second body , the 5d mark3 af i guess it's too much for me, i mean i will never use so many points
i use almost the center point
and i want only a trusty camera and af
Well Mantra I think then a 6D will be a good backup since you don't need the extra AF points or AI servo settings and are happy with one cross-type center point. I mean we existed quite happily for years with the 5D2 and if not for the advent of the 5D3 would still be using the mark 2.
and i don't like one think about the mark3 , it's hard to focus in low light, i mean the focusing points light up....
The focus points can and do light up if you hit the AF selection button ( top right of rear panel ) As a user of the 5D3 I have had no issues using the black focusing point. However if you are concerned, let me allay your fears in saying that the AF on the 5D3 is stellar. I don't recall having to struggle with AF in the time that I've had it. Won't say the same about the 5D2 though, even if that problem was not insurmountable.
Houston , i undestood , what i don't understand is dxo , for example they put some cheap dsrl forward my 5d mark II ,and they are 1.5 sensors

I don't think DXO do themselves and anyone else much favour in creating their ranking system. It looks really strange to have as you say, a lesser item comprehensively beat a pro model. DXO do state I believe that their rating should be taken in comparison only with a similar sensor size. They then go along and rank the D800 at 96% or something and place it at No 1 while it has some 36MPs!!! I'd stay with DP Review
