Evan pretty much nailed it, but here's my opinion too.
Pros of camcorder:
-Longer recording time.
-Can be easier to focus (also has autofocus if you for some reason need that)
-You can get a smooth zoom while filming
-more auto features in general, not that you really need that
-more sturdy without a stabilizer
Cons of camcorder:
-depth of field isn't very shallow and 35mm adapters are expensive and a hassle
-looks like the one you want doesn't shoot at 720p60p
Pros of DSLR:
-very shallow depth of field for cheap
-small and very portable
-720p60p in some models
cons of DSLR:
-can't get a smooth zoom. lenses aren't really built for that and you will lose focus
-limited recording time
-requires more knowledge of shutter speed, aperture, iso, etc
-too small to be stable
-on-camera audio generally sucks
that being said, i would choose a DSLR. and don't go with the 7D, it's just a waste of money these days. the T2i and 7D are exactly equal for video, the only difference is the 7D is more durable. the T3i is even better for video than the 7D, as is the 60D (the video will still look the same as the 7D, but the cameras have better features for video). Also, the 5D doesn't really blow any other DSLRs out of the water necessarily. while it's a bomb camera for filming actual films (where you would always be shooting at 1080p24p), it lacks 720p60p, which was a huge, huge downfall for me. plus there is no Magic Lantern for it, meaning it has less features for video than a Magic Lanterned T2i, T3i, or 60D.
