Noisy IS on 24-105mm F4

[daniemare]

If this has been hashed out before, I apologize, but I did try to search the topic but only got ISO results

As an excited owner of a new 6D and got the 24-105 L with it I noticed a very noisy sound from the lens while keeping the shutter button half depressed (i.e. locing focus). I know this is the IS and even confirmed by switching it off and the noise goes away.

Now I understand that IS is actually a motorized movement of a lens group and thus expect a bit of a sound and all of my IS lenses does that, but this sounds suspiciously louder, louder even than my Sigma 17-50 F2.8 OS and that I did not expect.

Is this normal or should I take it back to the store? To describe the noise level is difficult, but it is noticebly louder than my 100L macro and as my Sigma

Thanks

At Building Panoramics we have two 24-105's and one has louder IS than the other. Both work fine though.
As you have pointed out though, it's difficult to define "noisy"

Really depends what you mean by noisy. My 24-105 is significantly louder than my sigma 17-50 f/2.8 OS, especially when it starts up you can hear a pretty noticeable chirp. My 70-200 is silent in operation but the startup/stopping causes a pretty loud noise. All work fine, except for the sigma actually that went in last week for an AF issue. So i wouldnt worry about it unless there is something actually wrong with the operation.

Mine is loud too. It's normal for this lens.
