I read somewhere that since the digital cameras use shorter lenses (starting
around 6mm, I think), their depth of field is MUCH greater.
...
Can anyone comment on the depth of field differences between digital and film?
There's no free lunch. The focal length is shorter because the
imaging area is smaller, which results in proportionately larger
"circles of confusion," and the fractions cancel out, and you get the
same depth of field for a given exposure.
Often these lenses give greater depth of field because they have a
tiny aperture, NOT because of their tiny focal length.
