Is the depth of field deeper for digital cameras?
quote: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. and quote: For example, an Olympus C-4000Z (1:5 ratio) at F/2.8 provides acceptable sharpness in the same range as a 35 mm camera with the lens closed down to F/14 i.e., 5*2.8 (at the same equivalent focal length, i.e., image angle). The Olympus E-20 has the focal length ratio of 1:4, therefore its lens at F/2.8 provides depth of field of an equivalent 35-mm camera lens at F/11.2.from: Depth of field for digital cameras This applies only to the small-sensor cameras. If you don’t mind a little mathematics, this reference is good for dSLR’s, which use larger sensors: www.photo.
