It's kind of an Apples vs Oranges question. They're very different cameras. The big difference being the size of the imager. The EX1 uses a 1/2" chip, whereas the DSLRs use a full frame 35mm chip. That's a huge difference. That allows the DSLR to use 35mm lenses and get the characteristics of those lenses, one of which is the shallow DOF. That being said, when you consider the "total" or "whole" of the cameras, I still believe the EX1 is a far superior camera than any DSLR. I make a living with my EX1. I would have some difficulties doing so with a DSLR because of some of the serious drawbacks they present.
