I've got a 17-40 canon f4 lens that has recently developed a few faults. The manual focus option no longer works (it always attempts to focus itself), autofocus is now incorrect (always looks blurred) and the apature constantly reads 00 on the camera. The camera works fine with all my other lenses and i've checked the electrical contacts and they all seem clean.
I'm guessing since the lens outwardly looks in perfect condition i shouldnt have a problem sending it back to canon for repair (its about 4months old), the only problem is that I dont think i returnded that little warranty card they give you in the lens box. Should i try and source another one and send it in before informing canon of my problem, just incase they say the warranty in only valid if the card was returned. Or will I be fine to give em a ring anyway and sort out the repair tomorrow????
Cheers for any help!!!
