Hey everyone, this is a fairly simple question, but one that has been bugging me for awhile
What exactly does the F/# mean in the description of camera lenses?
Take this one for example:
http://www.adorama.com/CA702004AFU.html
It says Canon EF 70-200mm f/4L; some say f/5.6, some say f/4-5.6, but what exactly does that mean?
What # is more desirable?
