Well you can't not get depth of field with any camera- it's just a question of what kind of depth of field you are wanting. I'm going to presume you're referring to shallow depth of field where the background is out of focus while the subject remains sharp. With the stock lens you can do some tricks to create a shallow depth of field as you can to some extent with any camera-
Zoom in to the longest possible lens and back up from the subject if neccesary to get the shot you want.
Use the widest possible aperture- controlling exposure through the ND filters and adding additional filters if that doesn't do the trick in bright lighting.
If that still doesn't do it then you want to go with the 35mm lens adapters such as the Letus, MovieTube, Redrock, P+S Technics and attach cinema lenses. That gets a lot more expensive but the results are worthwhile if that's the look you're after. Was that what you were looking for?
