i have a canon ef 600mm f4L USM (without image stablization) and i need a new lens hood. i understand this lens and the new version use two different hoods, but are they intechangable?
the locking mechanism broke on my old lens hood and i damaged the screw holes that attach it to the hood removing it. i would like to not replace the hood since its $550+, can canon help me and get a new one attached some how?
i have tried every thing in the book for glues but want to get a permanent solution, hopefully without buying a new hood, but i'll do it if i have to.

Mike,
I don't know if the new hoods are interchangeable with yours, but I had the same problem with an old FD 300 f2.8L lens. The spring-loaded catch broke within a month of ownership and because I was in Asia at the time, I couldn't just "send it in".
My solution was to lose the spring-loaded mechanism altogether and construct an attachment that used a small, knurled screw to apply pressure to the lens. This attached the hood with a much better grip and never failed in 20-some years of use.
In your case, you've stripped out the mount holes in the hood, so simply tap out the holes to a larger thread size and mount a threaded metal plate which would hold a knurled screw. It's easier than you think.
In my case, I walked into a True Value Hardware store and the guy knew right away what was needed. I walked out in ten minutes with a new hood attachment mechanism.
