I agree with JCO. DOF depends on the magnifcation by the lens. At
typical object distances (>1m), the short focal length (e.g. 10mm)
lenses of digital cameras can be used at almost constant and very small
(<1:100) magnification, hence the large DOF.

I'm sure most of us agree to th opposite. Sertainly a 100 mm gives you less DOF than a
50 mm. That's why smaller formats - lika many digital cameras - have larger DOF,
provided the same angle of view is obtained by a shorter focal length.Jens

W R O N G ! ! the 100mm will have exact same DOF as the 50mm at the same
magnification and aperture. focal length has no effect on DOF, it is determined solely
by magnification and aperture.JCO
