I've been up and down about DSLR video. Currently I'm – on balance – postive.
Audio: a decent recorder like one of the Zooms is easy to sync nowadays and can give outstanding sound.
Video: Recording in true grogressive. Great image quality – especially low light.
Lens selection: Creative possibilities.
On the other hand:
Focus: Requires lots of advance planning for manual adjustment.
Monitoring: Will need to invest in something.
In general, many more moving parts,
BUT…very unobtrusive to subjects. (Personally, I think that's huge, which is why I was shouting.)
It depends entirely on what you shoot and how you shoot. If you are shooting setups, narrative fiction, crew, DSLR is fabulous. See all the features and TV shows that are using DSLRs. If you're doing run and gun, one man band, in my view you simply don't have the control on the camera to get the shots you want. How can you do a low angle shot when you can't see the viewfinder?
