conraderb Posted September 12, 2005 Share Posted September 12, 2005 hi folks - I'm trying to get a sense of what the audible noise is like on the 70-200 2.8 IS. I have searched for this, but the only NOISE that people discuss is visual noise. I heard that the IS system is noisy, and I'm interested in hearing people's experiences regarding how loud this lens is when using the IS. thanks. conrad Link to comment Share on other sites More sharing options...
KenPapai Posted September 12, 2005 Share Posted September 12, 2005 I've also heard that the 20D's shutter is noisy (even as compared to the 10D's). It's not. Compared to a motor-drive film camera those DSLR shutters are quiet. The I.S. on the 70-200 is NOT 'that' noisy. Link to comment Share on other sites More sharing options...
steve_dunn2 Posted September 12, 2005 Share Posted September 12, 2005 <p>My 20D is much louder than my Elan 7E. Then again, the Elan is one of the quietest 35mm SLRs around.</p> <p>I have only briefly played with the 70-200 IS, and that was in a noisy environment. I have been using the 28-135 IS for several years, and the 300/4 IS for a few years. Neither one is what I'd call noisy. There is some noise, a bit more from the 300 than from the 28-135, but I suspect someone standing next to me probably wouldn't hear it except in a very quiet room.</p> Link to comment Share on other sites More sharing options...
conraderb Posted September 12, 2005 Author Share Posted September 12, 2005 thanks for the responses. to be clear, I wasn't interested in noise from the combination of a lens and a camera body. I realize that a camera body will sound the same, no matter what lens is on it, so I just wanted to focus on what the IS sounds like if you can describe it and how it might compare to a USM focusing sound - is it a whirring sound? a grinding sound? a pleasant hum? is it (as I would expect) quieter to use the lens when the IS is not on? thanks. conrad Link to comment Share on other sites More sharing options...
goulden Posted September 12, 2005 Share Posted September 12, 2005 kind of a grinding/whirring noise but it's not very loud unless you're right up next to the camera, so the person taking the shot hears it but someone a few meters away probably won't and the shutter noise is much louder than it. nobody has ever commented that my lens is making any noise when i sometimes use it for portraits Link to comment Share on other sites More sharing options...
ivanskavinsky Posted September 12, 2005 Share Posted September 12, 2005 Conrad, the only person that should be able to hear it is you! I am only aware of it in an absolutely quiet room and then only because I can feel it through my cheek. Bystanders can't hear it, but they can hear the shutter slap and motor drive... Why is the noise SO important to you on a lens that is designed for tele work? It's closest focus is easily outside the range you could hear the Is in a perfectly queit room. It's one of Canons very best lenses, you will not be dissapointed with the results and options it gives you.<div></div> Link to comment Share on other sites More sharing options...
andrew_ito Posted September 12, 2005 Share Posted September 12, 2005 I would describe it as a light whirring sound. It's not bad by any means. OTOH, the 20D is much louder than the 10D. I would call the focusing of the Tamron 28-75 XR Di louder than the sound of the IS to give you an idea of the volume. Link to comment Share on other sites More sharing options...
conraderb Posted September 12, 2005 Author Share Posted September 12, 2005 by the way - I was asking more out of curiosity than concern. I'm sure that it would have come up in a review if it were an issue, but I was just interested. I never thought that IS would be noisy - I figured that it is some kind of plastic gel membrance that just cancels your hand vibrations (I'm going to go research this). thanks for the feedback.

The one you find in DSLRs? >> I heard that the IS system is noisy, and I'm interested in hearing people's experiences regarding how loud this lens is when using the IS. The only IS lens I used was the 300/4 IS. It was unheardable under any normal shooting conditions. Few months after I bought it I used it in a completely quiet room. I suddenly heard a strange and very faint noise. I started walking around the room to find its source. It took me several minutes to find out that it was the IS system that made it. I can't imagine that the 70-200/2.8 IS will be any louder. Happy shooting, Yakim. Link to comment Share on other sites More sharing options...

It's an active system which detects and counteracts motion, not a simple passive damper. It consists of two gyroscopic sensors which are used to detect motion (up/down and left/right), and a set of actuators to shift a group of lens elements to counteract the motion it detects. There's a little bit (but only a very little) of information on it <a href="http://www.canon.com/camera-museum/tech/room/f_index.html">in the Technical Room section of the Canon Camera Museum</a>.</p> Link to comment Share on other sites More sharing options...
photo_guru1 Posted September 16, 2005 Share Posted September 16, 2005 What if when the lens is in AI Servo mode, continuously focus tracking a moving subject. It follows that the IS would not come into stationary and continues making noises in the course of shooting. Is this the case? Anyone has experience?
