The depth of field characteristics is a function of the focal length and aperture - independent of the film/sensor format. However, the coverage on the sensor angle is dependent of the film/sensor format. The smaller a sensor, the shorter the focal length to that will be a "normal lens" what ever you want normal to mean but it usually means the diagonal of the image area is equal to the focal length. One of the issues I have with the small sensor is it is very difficult to get any creative control on the depth of field unless you go so long relative to the sensor size it becomes unmanageable. The 35 mm format is marginal when it comes to creative depth of field control. The medium format is much better and of course the view camera is the best with it's movements and long normal lens. So that's the reason that I am waiting for awhile before I consider digital for anything more than a P&S vacation camera. If I were a newspaper photographer I would probably think otherwise - but now there is a photographer down in Miami under a little bit heat with some lawyers demanding to see his negative of the photo he took during the Kentucky Derby - a negative he can't produce because it was taken with a digital.
