Default Grinding ..... lens noise

I just received my new 55-250mm lens for my T1i. When I depress the shutter to focus, there is a grinding noise until I let up on the shutter again. I've heard/read that some lenses do grind, but that there's no cause for concern.

Since this is a Canon lens that is often included w/the T1i when purchased, I'm surprised to hear any noise.

Should I be concerned? Any suggestions/comments/etc would be greatly appreciated.

Thanx in advance,

...k...

If it is a small humming it is the IS spinning up, it is a a real grinding as it focus. Return the lens for a new one.

Well, bummer ... was hoping I'd not have to do that, but will do and wait impatiently for a replacement.

Thnx so much for the info.

That's what was happening with my Sony a200.
Every time I would zoom in, in a low light situation... it would grind almost every time.

I got to where I could only use the camera outside on like two settings.

trn off the IS and try it again. If its the IS then you should get no more noise if its focusing then the noise will still be there

Agree try turning off the IS and see if it goes away.
Or go to a store and try testing a few of their copies of the lens.

Also searching google for " 55-250 noise " gets a lot of hits from other people experiencing the same thing.
Might just be normal operation, most of the components in these modern lenses are all made of plastics.,

It's probably the gyros on the IS spinning up and therefore nothing to worry about.
