Help: 24-105L making faint noises

[VitorMachado]

Brand new 24-105 and I just noticed a small little noise. Every time I half-click my shutter for AF, the lens does it's job but also makes a faint sound. Its almost as if something inside it's motor is still spinning. Yes I do know what an AF motor sounds like and thats not the "normal" sound. Anyone have these same issues?

IS? Did you do the same thing with IS off?

The IS starts only when you half press the shutter button and stops about 2 seconds after you release it. That is almost certainly what you are hearing.

I too had a similar query when I got the 100-400, that lens make a fairly loud and audible clunk when the IS is activated.

The 24-105 is fairly quiet by comparison. The short buzzing / whizzing sound is most definitely the IS engaging.

Try the 300/4L IS sometime - an even louder clunk you can hear and feel, and during operation the IS is sort of a low growl.

You're not wrong about the rowdy IS in the 300 f/4is! That's a perfect description of the sound. You can hear it from half a block away! But a small price to pay for a wonderful lens. I should never have sold mine when I upgraded to the much quieter 300 f/2.8is.

The 300 f/4is must have been one on Canon's earliest IS efforts. It must have been mid 1990's when I got mine. And apart from getting quieter, hasn't IS matured in the meantime?

Yes! I'm hard of hearing, when I got my 300mm f/4, I could feel the clunk, and hear the growl. I was ready to send it to Canon, but I remembered reading about it and did a little investigation.
