In FoCal's test, the rather big surprise is how inaccurate and variable contrast-detect AF is on both the 5DII and the 7D.
I didn't know that and expected my 60d af to be always spot on - is this your personal experience or do you have sources on that? Afaik even lensrentals uses contrast af as the comparison for perfect af accuracy?
, the battery drain with wifi and GPS turned on is quite significant
... as far as I've read wifi is the main culprit, while gps surprisingly seems to draw little power when the interval is set to 60sec.
Why do the mention - "Relatively unsophisticated Auto ISO"?
Because there's Magic Lantern with sophisticated auto iso :-)
nothing but a re-packaged 5D II, crippled all around.
Imho the 6d is still overpriced and certainly not a feather in Canon's cap, but you are either ignorant or trolling: The list of advantages of the 6d over the older 5d2 is significant, though we know Canon felt like downgrading some core specs (x-sync, shutter speed, shutter rating): http://www.canonrumors.com/forum/index.php?topic=12582.msg226467#msg226467
Overall even weaker than the nothing-to-write-home-about Nikon D600.
... but you might feel different about writing home about the 6d after trying to use the d600 af in low light.The main part in the dpreview review that was missing from the preview is this:
Focus acquisition on the EOS 6D displays all the hallmarks of mature phase detection AF performance. The camera is quick to lock focus and under most conditions does so with a high degree of accuracy. In reviewing hundreds of images shot with the 6D, the vast majority of shots that did lack critical sharpness were due to either subject or camera movement.
