The 6D works in the DARK, unlike the 5D and 5D2.
(it will AF down to -3 EV I think...) And I think the 5D2 only works until +0.5. Big difference there.
Which translates into: it will work better most of time (even in daylight) when trying to focus on dark clothing or any dark or low contrast subject. this is worth a lot IMO.
Also it is said that the periphery points are much better now with the 6D.
For many it may be the perfect entry into FF and the benefits this sized sensor brings with it will be exploited as best possible. Three decades as a 35mm film shooter, one with a disability, the lighter weight of the 6D; it's WiFi/Smartphone pairing, are huge pluses!
The 6D lets me get back to no crop factor shooting with a digital body. There are many who see this entry level FF as a disappointment, I'm not one of those that see this body in that negative light. For me with all it's newer tech it's seems just prefect for my style of shooting, it's a fantastic lower cost alternative that may make it easier for me physically to shoot FF...
Back in 07 the 40D struck a great balance of tech and was my entry into digital. A kit with that old trusty crop body and a new tech FF body will make a great combo in 2013. Why am I really waiting, I need to save a bit more to get the new 24-70 f4L IS to complete my f4L glass!
To those that get the 6D early, have lots of eosfun and please post some images for this slow adopter...I've got me a Ginko to shoot tomorrow, it's blush is pure yellow, lets hope it doesn't rain much tomorrow so my crap 40D with 17-40L can handle it
Happy holidays all
