I recently purchased a Canon EF 100mm f/2.8 USM Macro lens from B&H Photo. Yes, I did get the Canon USA warranty. <p> I noticed that the lens has a scratch inside either on the inside of the front element or on the front of the second element. It appears quite bright when looking through the lens from the rear. I fear flare may be an issue and would like to get the lens repaired or replaced. <p> Anyone else seen this from a Canon lens right out of the box? Of course, B&H Photo doesn't want to take it back stating it's a Canon issue. I've taken it to an authorized Canon service center where I live and they state I'll have to send it back to Canon USA to have them look at the lens. <p> I've never had this kind of problem with a Canon lens. Just want to know how others have dealt with this. <p> I've had two EOS-5 repaired at the same facility for the infamous Command Dial problem. Never had a lens problem right out of the box though. <p> I'm wondering how fair Canon USA is to deal with for something like this.
