Noisy Canon IS lens - ? problem

[ullyn]

Hi,

I just got the Canon 70-200 IS F4 lens yesterday. When it focuses it makes a whirring noise but rougher, like ball bearings moving that lasts for about 5 seconds after it focuses on the subject. There is a click when I half press the shutter, the whirring noise and then another click at the end while the shutter is still half pressed. My old non IS lens of the same kind did not make this kind of noise. Is this normal?

Thanks,

Ullyn

It's likely the IS motor inside the lens. Any IS lenses I've used have done the same thing.

Really? My 28-135 IS lens is pretty quiet.

The IS noise varies from lens to lens. 

My 24-105mm's IS makes very little noise but I shot with the 100-400mm IS and 300mm IS which makes considerably more noise.  If I remember correctly, the 28-135mm I owned made a little noise, mainly when the IS started up and shut down.

Did you buy it used?

I have the 2.8 and mine is as quiet as can be.

Hi,

Thanks for the responses. I did go in and get another one which is a lot quieter.
