I am sorry but I consider this poll silly!
D800 is to be compared to 5D3 not 5D2. You compare a current camera with an obsolete one!
I think his point is that he's comparing the 5DII as a 'game-changing sensor' because of the much higher MP than any FF south of $7K to the D800 with more FF MP than anything else out there at the time (or still, the a7R isn't a dSLR). He's asking 'what did you do in 2008-9 about the 5DII' vs. what did you do lately about the D800.
I still don't really get the point, though...
That's right, the reason it's the 5D2 and not 5D3 is I'm wondering how many people are on this board right now because of the 5D2 five or six years ago (when it was new and the best camera you could get).
Also I've unlocked the poll so you don't have to vote to see the results.
