So I wished for a FF Rebel and I guess I just about got it. (I even thought they will call it a 70D)
Am I disappointed about the lack of a Pop-up flash and 7D like AF, yes very much so. Would I have liked a little more fps, yes, but again it is 1fps faster than my current camera (T1i)
Do I care about the view finder (97%), fixed screen and no-touch screen, not at all because it is better than/I do not have it on my current Rebel. Hell from what I understand just being a pentaprism instead of a pentamirror is all the upgrade I need.
Is the GPS and WiFi an unexpected bonus, for sure. And I do not even have to buy new memory cards.
Does the D600 look better on paper, yes. Can I switch??? My 28 F1.8, 50 F1.4 100 F2.8L macro and 70-200 F4 and 430EXII says no. Does this dissapoint me, no. All my lenses were bought used (exept for the 50mm), Canon is far more popular were I live and this make it much easier for me to keep getting what I need at far lower than MSRP through kijiji and craigslist.
This camera is not for those wanting a cheap 5DIII, nor those upgrading at every release. Its for hobbyists like me who can't extract the capabilities of the 6D to its fullest, let alone the incremental difference to the D600.
I am excited and will get one - as soon the first price drops come along.
