The fundamental difference between a traditional SLR and a DSLR WRT dust collection is that DSLRs have a fixed sensing element, the film surface obviously moves frame to frame so is generally far less of a problem. I'm sure that the same amount of dust gets sucked in due to lens focus/zoom movements and enters the mirror box whilst lenses are being changed but yes it does pose more of a problem for DSLRs. Systems have been developed to attempt to counter the problem but basically a good puff of clean air will solve most DSLR dust problems.
