Depth of field for digital cameras

“I expected the depth of field in digital cameras to be significantly greater than that in 35 mm models. Everybody and his mother knows that. What I didn’t expect, is how large the difference is. More, the relationship turns out to be quite simple. It can be summarized as the N-times-F Rule: The depth of field of a digital camera with a lens of the 1:N focal length equivalence ratio at a given F-setting is the same as that of a 35 mm camera with a lens closed down to the aperture number of F multiplied by N.”
