'Magic Drainpipe' - A Question

I bought an 80-200 f2.8L via eBay, and before I fully accept it I have a question about the AF:On this one the AF is slightly noisy, and it 'clunks' a little. Is this normal for the Magic Drainpipe? It is not objectionably loud, just noticeable.Thanks in advance.Have Fun,

clunks? can you post a .wav file so we can hear it?

'Clunk' is a relative term - let's just say I can hear it when it stops focusing. I don't have a way to post a .wav file.Have Fun,

It's PROBABLY normal considering that lens doesn't have USM.

This is my first big EF lens that hasn't had USM, so it was a little unusual. I guess its normal, thanks for the replies.

Have Fun,

Mine does the same thing, but it takes great pictures.

During normal focusing ranges, mine has never had what would be considered a 'clunk' but when you hit the edge of the focus range (ie, you're trying to focus on something closer than the minimum focus distance), I can hear a little clunk when it hits the limit. Is that what you mean?
