Broken lens on first use ?

[rudi_tapper]

Anyone else out there managed to knacker a lens the first time they use it ? Got my 500mm lens last week and took it out today. Somehow managed to get the lens hood on wonky but didnt notice until after tightening the locking knob. Now the knob doesnt do anything when I turn it and the hood is stuck at a jaunty angle on my lens. Just sent an email to Canon for advice on how to get it off :oops:

Ooops...:oops:

They'll probably ask you to send it in or tell you just pull harder ;)

Duno if you wana risk it but you cold try and use the back side of a knife to wedge it off :confused:

i throw mine on and off on my 500 sounds like you have got it under the lip if the screw is undone it should just pull off.

Hmmm. I couldn't pull it off as the locking device is extended and in the groove that it fits into, but I've given the hood a gentle tap and its now straight. Knob still doesnt do anything so its still stuck on :(

surly you did not get it on the lip on the white body .
a couple of shots of mine undone and tight'nd dont know if this will help but shows what might be stuck

I just had my lens hood stick. First time in the 1 1/2 years I have owned it. I am the original owner. To make a very long story short, after talking to Canon tech support thye recommended pushing out the roll pin that holds the nob on to expose the threaded screw that goes though the T. They thought the screw would then come out. WRONG! There is the wedge that tightens the hood to the lens, and the wedge should be loosely connected to the threaded screw by a snap ring or E clip. Turns out the snap ring was missing and the wedge had been held in place to the hood by a small piece of fiberglass tape. So the wedge would move up and down because the tape was flexible, but finally it became stuck.

After unscrewing the threaded screw until I met resistance, I then used some small tools to lever the wedge away from the lens and then was able to remove the hood without any damage to the hood or lens. The repair would require a tiny snap ring that probably costs ten cents. The piece is on its way to Canon Irvine; they have indicated they will probably replace it without charge after they have had a chance to look at it.
