I mean for $400 more one could even go full frame by selecting Sony (though that camera is geared for a different genre of photography admittedly), and for $700 more they could do it really well with a D700.
another $700 more is quite a lot.
what Canon did was address the gap between APS-C and APS-H cameras, with some extras thrown in. there's nothing underwhelming, unless you expected them to start putting 1-series features in a sub-$2000 body.
AF is the same if not superior to the D300 in tracking, the body has weather sealing, the viewfinder as large as it can get, and the ergonomics are improved. AF points can be linked to the camera orientation and it gains double-cross center AF point and spot AF. what's so "underwhelming"?
I suppose the days of Canon being the default brand of choice for professionals are long behind us eh?
when was Canon the "default brand of choice"? 2005, when the 5D came out?
Canon has only been a standard in sports. portraiture, weddings, etc. have always been split.
