I've been wanting to upgrade from the 550d, pretty much entirely because of the buffer, but In my eyes it certainly wasn't worth spending another £200 for a 60d just to get 1.3fps faster shooting and a 20 frames buffer vs the 6 of the t2i, but now I've seen the d7000, same price as the 60d but from what I see it's a hell of a lot better,
these are the advantages to me:
great noise handling even up to 6400 iso it seemed
(buffer is lacking at about 11/12 frames but that's good enough(can you set a slower continous shooting speed like on the 50/60d(?)?))
Significantly higher dynamic range(one of the main reasons I got a dslr)
2 sd slots
weatherproofing & magnesium body(partially)
1.5x crop vs canon's 1.62
POSSIBLY a much higher video resolution, when I watched a video comparision between the two at 1080p(supposedly) the d7000 was a lot sharper than the 5diii, but I have a feeling they may have just shot at 720p with the canon(somebody chime in here please(or maybe it was to do with in camera sharpening)
Excellent selection of lenses(although being stuck to mainly nikon and being unable to use other vintage lenses is kind of annoying, but it's really only a slight inconvenience)
Seems a lot of nikon lenses are af-s(apparently with full time manual focus?) this is a big plus to me, is it the equivalent of canon usm(speedwise)
Ability to use/share lenses with everyone I know.
Pentaprism(although having never used one I don't know how much of a difference this makes so I'm not really counting it)
41 af points, 9 cross type
Selling canon setup, but I'm not heavily invested and I won't lose much.
lack of 60p at all with the d7000, but I never find myself needing/wanting to use it.
a little bit trickier to manually expose in video mode
have to buy an intervalometer,
No equivalent of canon 70-200 f4 from what I could see, for the price anyway.
I'm trying to think of negatives to add to the list, I'm seriously considering getting it just for the huge advantages for the very little price increase.
