i dropped and dented the metal mount on my 70-200 f4. It would have been at least $185 for canon to repair and they don't give you a "final" estimate till after you pay the "initial" estimate and then they open it. Should it be more, they reimburse you the $185( in my case) and recharge you the new larger estimate. Should you decide not to have it repaired, you lose the original estimate amount you paid ( ie $185 for mine). It's according to lens though which is what that link should show you. But beware, that is not a final estimate and canon told me it could be up to double for mine...to replace a $40 part in my case.
This was for the NJ repair center ( although I think I actually talked to someone in Virginia iirc). When i called in they originally told me $100, then once i sent it in they gave me the "tentative" $185 estimate in an email then the $300+ estimate when i called again to ask why estimate #2 was so much more than they quoted me over the phone. this was in July so doubt it's much different now
KEH on the other hand looked at it for free and fixed it total, including shipping back to me, for $145
