If you are lucky.  Most lenses do not match exactly, whether prime or zoom.
One advantage of the zoom lenses is that you can visually match one lens to
the other.

Digital superior to film???   Maybe you should talk to Eastman Kodak.  I
have in front of me a rather interesting statement from them (Kodak
publication H-327): "high definition (hi def' e-nish en) n.   1. See film.
With resolution six times greater than the closest digital format, film is,
and will be, the definitive origination medium."  Those are Kodak's very
words, not mine.

They also state that on motion picture film (the images of which are less
than half the area of those in a 35mm still camera) there are 12.746752
Megapixels per 35 frame.  That would be over 25 Megapixels on a 35mm still
frame.  A digital camera over 4 Megapixels it VERY expensive!

Usually you are best off to use a particular medium in its native format.
If you are only going to put your images on a computer, such as for personal
viewing or the Internet, a digital camera is good enough.  But, if you are
going to project them (let alone look at them in a good quality viewer), you
are going to be far better off shooting with a film camera.
