Hi, I wonder if anyone might be able to answer a question for me, or direct me to where I could find the answer. I am fairly new to digital photography, and I have been puzzled as to why it seems impossible to find a digital SLR-type camera with a range of apertures any greater than F2.8 to F11 (at the most)? Is it possible to obtain the same depth of field with these cameras as it is with a true SLR camera (e.g. at a traditional setting of F16 or more) - i.e. do the aperture settings on a digital camera not correspond directly to those on an SLR, is F11 on a digital different to F11 on an SLR? I'd be really grateful to anyone who might be able to shed some light on this for me! Thanks!
