My 24-104 F4L lens started to develop annoying zoom creep. The zoom creep started when the lens was a couple of months old but was only minor so I did not send it in to Canon at the time as I did not want to be without it. Yes I know I should have had it fixed under warranty. So the lens is now two years old and the Zoom creep developed to the point where it has now become very annoying and I have stopped using it as a walk around lens which was the reason for choosing it over the 24-70.
So I though it was time to send it in to Canon to have this rectified. The lens was sent off to canon and I received an Email from their service centre in the UK informing me that it had been forwarded to one of their authorised repairers as I would get a quicker response. The repairer sent me an estimate for the repair which I authorised and to my surprise it turned up this morning so I was over the moon as I was not expecting to have this for the bank holiday here in the UK. Just over a weeks turn around was a really good response. However I put the lens on my camera and checked to ensure the Zoom was now going to stay put. The zoom creep is now significantly worse than it was when I set this lens in for repair! What was an annoyance is now a fault that would prevent me trusting this lens for use on a tripod the Zoom moves that easily and I am £160 out of pocket.
Has anyone else had a similar issue and if so how did you resolve it? I have contacted the repairer however it is Saturday morning here and no one is in the office so I will have to wait for a reply Tuesday to see what they intend to do about it. My fear is that this is going to be one of those occasions where the lens is out of use for a significant amount of time going backwards and forwards by post to the repair facility to try and get this rectified.
