Default f stops equivalence of digital cameras

Hi,

I was wondering if the f stops of digital cameras directly correlates to that of film cameras. I'm wondering this because I understand that due to the compactness of these cameras that DOF is not the same and I wonder if the f stop ratings are also different due to the compactness of the lens.

thanks

F-stop and shutter speed correspond to film camera (and lightmeter), but like you said not DOF because of the small relative size of the CCD!

Well ... DOF is DOF, but the DOF at a given fstoip will be much bigger because the folcaleneghts used with smaller chip are smaller.
