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!

Rick Hunter: I'm one of those neophytes that need help from you pros. I have a Canon digital Rebel that is several years old and 3 Tokina "Pro"f 2.8 lenses---16-35mm, 28-70mm, 70-200mm. I'm looking to upgrade to the Canon L lenses and would like to know what would be recommended for...

sportsman: I was wondering if anyone had this lens and how you liked it. I thought it would be a great lens for my 20D. It should be good for indoor sports as well as a general use lens around the house that is very versatile. Any thoughts would be appreciated. Oddly I haven't taken to mine yet....
