Overall, though, it's difficult to shake the feeling that the EOS 6D simply lacks the 'wow' factor of its main rival. Whereas Nikon seems to have taken the approach of taking away as little as possible from D800 when creating the D600, Canon appears almost to have gone the other way, removing as much as it thinks it can get away with at the price. The result is the kind of conservative, slightly unimaginative design that's become the company's hallmark. It's still bound to be a very good camera, of course; just perhaps not quite as good as it could be. -http://www.dpreview.com/previews/canon-eos-6d/6- DPReview
My FF upgrade will now be to a 5D2 - NOT the 6D! From my perspective the 6D is disappointing, DPReview summed it all up, "conservative, slightly unimaginative design that's become the company's hallmark." I have no plans to jump back to Nikon but Canon needs to watch their back. Technology moves ahead at warp speed and if Canon's stodgy approach continues, they may loose market share and eventually their dominance in the marketplace.
