I have bee nworking my a$$ off lately at my job and the paychecks show it. And I soon might want to get the Canon 100-400 IS lens for my Xsi.
Can anyone tell me what the "L" series or "L" lens is and is it different from other versions of this lens. Also where to buy and if its only available from online dealers, is the shipping safe and insured? Any info would help a lot!!
