I know a little about digital photography: yes you can use digital
zoom but what it does is using just a part of the CMOS and
calculate the pixels from there for the full resolution image. This
leads to a loss of quality in the image, thus the use of the fancy
lenses for zoom :-). Of course, depending on the application it's
intended to, such a loss could be negligible.

Just my 2 cents.
