I have a Sony S-70 Digital which I enjoy working with. For some reason , I can't seem to get "depth of Field" effects, even though I am using it on manual aperture priority mode. Is this a limitation of the camera or digital camera's in general?

i'm not sure about your camera, but the depth of field is a calculation based on how wide your aperture is, the focal length (zoom) and the distance. for example if you have the aperture wide open (like f2.0) and a very close distance (like a foot) and zoomed in (like 3x) you will get a very shallow depth of field, and everything in the background will blurred out. it is definately not a limitation on digital cameras in general.

If you check the focal length of your lens, you will find that it is quite short. Because short focal length lenses have a greater depth of field than longer focal length lenses, any effects due to aperture change will not be readily apparent. It is akin to getting selective focus on 24mm wide angle lens in 35mm format
