Canon EF 24-70mm f/2.8L USM

Thought I'd get some "expert" opinion on this. at a local camera store today I found a USED canon 70-300 f4-5.6 IS lens for $250 less than the new price. since they said there is no warranty/guarantee with the lens I have some reservations, I tried it in the store and it seemed to work great and everything feels as snug as the new ones but when I tried the IS there is a noticeable vibration coming from the lens. Is that normal and should I error on the side of caution and not bother? there's no obvious marks on the and the guy behind the counter showed me how to watch for "impacting" on the lens and everything seems good. I guess the only thing really bothering me is the lack of warranty... but then again this is the only way I'd be able to afford anything like this for some time as my son's medical expenses have gone up again. :(

I have this lense and the 24-105L IS. I can't feel a vibration on either one when the gyros spin up. I can hear the noise of this happening, but can't feel anything through the barrel of the lense. If it were my money, I would steer clear if the store won't warranty it for any minimal amount of time.

Tkx for the info, I was hoping that someone with this lens would reply. I could hear it as well as feel it and the vibration was quite noticeable which is one of the major factors that put a doubt in my mind.

Did you happen to shoot through it?

At a bare minimum, I'd take my camera in shoot through it, ask the owner to hold it a day and go check out the photos.

No experience with IS, so I can't help ya there.

I did shoot through it with a camera in store and its "seemed" ok but like I mentioned the vibration was kinda annoying.

If something that is supposed to stablize the image is causing a vibration that is physically felt, I would "run not walk" away. Sounds like a bad gyro bearing, to me. Pretty well fatal to the mechanism, I would think.

It might take great pics without the IS, but why pay for something that probably doesn't work quite right?
