Lens
> Focal Length
Each
level of magnification is assigned a number, referred
to as the "focal length."
Lots
of magnification (telephoto) means a large focal length
number (like 100) while less magnification (wide angle)
means a smaller number (like 10).
Most
consumer camcorders don't even bother to list the focal
length number, but you should have a basic understanding
of the term, because professional camera operators will
often refer to the focal length number when describing
a zoom setting.
