Hi all professionals out there, as you guys can see, i'm a real beginner here. i currently own a canon 40d + 18-55mm kit lens, and i have a few questions about lenses in general.
I realized there are so many different kinda lenses out there for different purposes, and what does the USM stands for? and there is also IS USM etc etc. what do they actually mean? the price difference with regards to lenses without those acronyms is huge, i realized.
In addition, what is L lenses, and what's the reason for their hefty price tag?
Thanks in advance.
