I do. What do you need to know?
Generally, DSLR video is quite "filmic" and when good gear is used, doesn't fall apart at all. Also, you can get bokeh previously not available on this side of 35mm film.
I recommend starting with DVXUser forum
DVXuser.com -- The online community for filmmaking and going from there.
I have both Canon and Panasonic gear and now use Panasonic GH2 for video almost all the time. Canon still has a slights edge on stills (read: I invested too much money into Canon glass to get rid of it
) but it's video isn't quite up to par.
