I apologies for a such a newbie question.  My knowledge on optics is
limited, and even then
it's more on the microscopy side.  I could use some help on theory.  If
I mount 10x macro
lens on top of a 10x telephoto lens, will I receive 100x magnification?
Will there be
any distortion?  Will I run into empty magnification problems?  Thank
you.
If you could also point my to an lens or photography FAQ I would
appreciate it.
