Re: But I can't do this with a point-n-shoot

It's not being a dslr that controls the depth of field. it's the size of the sensor or film frame and the optical factors, like focal length and aperture of the lens. DoF was the same on 35mm film cameras as it is on full frame dslrs and would be on full frame mirrorless cameras using the same lenses. "Fast" shooting is a collection of factors that aren't dependent on the camera being a dslr, in fact, the flapping mirror of the dslr/slr is in some ways a limiting factor. "Movie" cameras use different shutter and finder systems to move along at 24 fps and higher rates. Of course with film, the film has to be moved at the necessary speed and with digital cameras, the image files must be moved through the processors to memory so the "horsepower" needs go up as the frame size/resolution and frame rate goes up. Also one needs to have some sort of viewfinder, exposure and focus system as well. The more one approaches cinema or video frame rates, the less the tradilonal slr mechanics suit the end use. The digital processing doesn't really depend on the form of the camera.
