I have just bought Canon's 70-300L zoom from Amazon.de. I am a little bit concerned regarding the noise from the IS mechanism. When active, the IS emits a hiss that is similar to the one from my previous 55-250 IS. That’s OK. What really worries me is the noise that the IS emits shortly when it’s activated and then deactivated. It’s actually a very loud buzz. This noise is produced only when the IS kicks-in and then when it stops. During operation, the IS sounds ‘normal’.

I was wondering if this strange behavior is normal. My other IS lenses do/did not produce this sound. Did somebody have a similar experience with this lens?

Otherwise, the lens is built like a tank. I am really looking forward to this weekend, to test it out.

I've owned my 70-300L IS for about 3 years now. I haven't really heard a buzz. Mine sounds what one would expect from the IS. Not totally silent but not loud either.
