Lens Another important part of the digital camera is the lens, no matter how
good the rest of the camera is, if it has a poor lens it wont take good
pictures. Modern digital cameras might come with zoom lenses, which allows
you to adjust the length of the lens to either move closer to the object or
further away.
Digital cameras usually come with two types of zoom on
them.
The first is the optical zoom which is identical
to that found on traditional cameras. When using optical zoom, you can
get closer to a particular object without any sacrifice in image
quality.
Digital zoom, however, is a new type of zoom that
is found only in digital cameras. When using digital zoom, the camera
itself modifies the image electronically to bring the object you are
photographing closer to you.
