Would anybody happen to know where I can get an instruction book/manual for the Canon EF 17-40mm f/4 L USM lens? Either by mail or on-line? Thanks!

Hi Everyone, My name is Jason and I'm the owner of a new online lens and equipment rental company named Glass and Gear . As the new guy in town I just wanted to spread the word that we're open. As I hate advertising like this, I always feel like a spammer doing it, I would like to offer the board...
