If you have a 18-200mm camera lens is no need or advantage of also having a 18-55mm?
I recently bought a Nikon D70, only the body. I am in need of a lens and was thinking of getting a 18-200mm, there is no reason to also get a 18-55mm? Thanks in advance!
The 18-55mm is cheap, is probably much smaller, lighter, less cumbersome to carry as a lens for each day.
