OK... So I think the 70-200 II IS design is faulty.

Not bad, but at 100% there is a lot of noise for just ISO 200... I have a shot at ISO 1600 with my 5D2 with less noise. Did you do really high amounts of sharpening?

Funny, I don't see much noise, but I'm still learning. I did do sharpening, but not much higher than I usually do. Great tip and comment though, because I love to learn, the only way to get better. :)

You could probably hold back on the sharpening a little bit. An additional technique is to use Lightroom's sharpening mask: http://www.image-space.com …sual_Sharpening​_Mask.html (external link)

Pretty much hold the alt-key and change the sharpen-mask slider so that only the important outlines are shown in white. These white parts are what will get sharpened.

This has the effect of (say) sharpening your camel's outline, without unnecessarily sharpening the background.

Oh crap... I didn't know that... See, I told you I'd learn something (and I'm not being sarcastic). I will give that a try, and follow the link you provided.

Thanks!!

Just bought a brand new one and mine is making the same IS sound at start up and stop of the IS. It definitely does not sound normal. During IS, it is the normal humming sound though. Also, from the brief testing the IS seems less effective than the V1 I had for a few years which is a 3 stop IS. I am most likely going to exchange this one.

my 70-200ii does make that loud noise when new but after extensive use the sound is gone...hopefully it will stay that way...

Also to make best use of the IS one need to wait for it to stabilize before clicking the shutter, verify this through the viewfinder... I can handhold this lens with 1/20 ss and still get relatively sharp pic...

Read through the thread just now. I got a new one on Saturday, and seeing as this is the first and only lens I own with IS, I really don't know what sounds are normal and which are not.

I have 15 days during which I can get an immediate replacement of the lens, after that is has to be sent to Canon.

How can I find out if my lens suffers from this? Can anyone record the sound or something? Is there a test to see if it happens?

Hope someone can help. Cheers!

Now you got me wondering! Going to test thoroughly as soon as I get home.

Searched "70-200 IS noise" on Youtube and found this video (external link). Is this the noise everyone talks about?

Cheers!

So, got home and headed straight to my camera bag.

Turned the camera on. With IS off there is no unusual noise.
After turning on IS, these is a noise whenever you half press the shutter button. I kept it pressed and looked through the viewfinder, wiggle the camera around and IS appears to work. When I let go of the shutter button it makes the noise again, after like one second.
So it would appear it makes this noise when it starts and stops the IS.

Like I said, I have no other lens with IS so I don't know if this is normal. I recorded a small video with sound, can somebody with knowledge of how it should work tell me if it is OK or if I need to return it ASAP?

Hope someone can shed some light on this. Cheers...

Sounds normal to me. I've had mine for over year and it makes that slight "woosh" sound when the IS engages and disengages and it works flawlessly. If you want noisy, get the 300mm f/4.0L IS. It clunks and grinds, but again it's normal as that's first generation IS. Stop worrying and go out and take pictures! :)
