That's not always the case, scenes of Slumdog millionaire (in the streets) were filmed purely with DSLR, same for the subway scenes of Black Swan. Not a feature film but the entire season 6 finale of House was exclusively shot on a 5D mkII, and a couple of small BBC series have been. I appreciate that of course 'proper' digital cinema cameras are better, but this shows that DSLRs are very much competent, and they are only going to get better.
