So, how do warranties work? I know there is a paper that talks about the warranty, what is covered what isnt. Is there any form I need to fill out and mail in for the warranty? I also somewhat recently got a EF 50mm F/1.4 and I dont know what happened to the warranty... Do I need any sort of proof with warranty? I am young and dont know how warranties work, ive never had anything under warranty break so I never had to do anything. ANy information is helpful...thanks!
