How is the body? Does it feel similar to the 60D? Also, how's the AF system. While it may not be like 5D3s but in it's own right is it snappy and quick? Cannot wait to see some IQ and ISO comparison between 6d, 5d2 and 5d3.
Ditto....from other posts it sounds like the high ISO sensor performance is on par with the mk3 (many are saying it's actually a touch better, not enough to be WOW, but still that's awesome!!). What I haven not heard about is the AF. How not good is it? LOL. Is it like the mk2, center point spot on but anything else forget about it? I shoot weddings and am considering what my secondary body will be (a second mk3 or possibly the 6d). I like many of the things I am hearing about the sensor, basically what I want is images that don't look out of place next to mk3 images. So, if the AF is decent, this may very well be my answer. Use the 6d with a 16-35 (or maybe my 24-70), then run with the 70-200 (or primes) on the mk3. If I am shooting mostly wide angle with it, as long as the AF is halfway decent I should be OK. I rather like the idea of the weight - usually I prefer something with some weight to it (it's one of the reasons I go with a grip!), but I rather like the idea of have as lighter weight ungripped body for the last 2 hours of a reception, where your more than likely holding the camera up over peoples heads. By that point your arms are tired, so hefting a mk3 with grip after shooting most of the day with a 70-200, it hurts!!!!! (and for that kind of stuff, center point only would be fine. I also do dig doing night time long exposure stuff - at first i didn't like the whole wifi idea - but the idea of being able to control the camera via my phone, that kind of rocks!
Long story short, how is the AF?
