Bought a CanonXTI with the kit lens. I would now like to buy one or two new lenses. What should I go with. I mostly take outdoor pictures such as scenery and animals. I would also like to get into Wedding Photography. I have done a couple weddings and enjoy doin then. So what do you think i should go with. I dont want to really buy any flashes or lighting right yet. Would you go with a IS lens or a a Canon L series??? Thanks for all your help. If you think I should get a flash please also let me know why and what help it would do. Thanks cant wait to hear back from you guys.
