There are a lot of differences? Because I was under the impression they were virtually clones of each other, as are most Canon/Nikons at any given price point.
"the choice is ultimately based on what you're looking to do with the camera."
How do you figure? They both have a carbon copy of each others specs list. There really is no feature differences. The Sony A77 on the other hand has a lot of unique features and specs, with unique advantages over these two cameras. Of course, its also a year newer.
They are both also almost identical in price for body only. The reason theres a $100-$200 price difference with the kit is that the 28-135 IS USM is a much better lens than the 18-105 that comes as a kit with the D7000.
*edit - though, unquestionably the Sony A77 is the winner for video recording. For some reason because the Sony isn't as popular of a brand name, people don't realize this. Its so funny how popularity can distort a persons thinking.
