mine does too- it's a very noisy lens from what I can find out on the internet- not sure howl oud yours is, but mine was kinda loud- thought it was defective too- but the lens works fine, focuses fine- etc- the noise mien makes is like a cross between a motor noise and a grinding noise=-

I haven't heard this noise on my lens when focusing. Are your images affected in any way?

I also hear the noise of the engine when the Shutter is ready for shuting, but the noise level is small and it does not bother me. I wish you success!

I haven't noticed noise from the shutter, but there is some noise when the camera is turned on - I suspect from the sensor cleaning unit. Noise, however, is not usually an issue since I shoot mostly outside.

I've never had that problem although I do know that you really need to hold the button down until you hear the shutter click almost an old-fashioned film camera or the picture won't take. Hope you find a solution to your problem!

Yes, I have not had any issues with this lens, in fact, I love it. I use the auto setting on the camera and all pics have been great!

Does the lens make a noise when it auto focuses or zooms? I make YouTube videos and if my camera zooms in the middle of me talking in a video that would just be distracting and awkward. :/

I think the 'shutter problem' can be traced to the lens or the settings, or a low light condition. Start adjusting the settings before you send it in for a new one. Also you need to change or recharge the battery occasionally.

I have the same lens and it's my favorite lens. Mine does not make any noise like you've described.

There are a number of things that could be happening. . . . is it blurry image, or camera shake. . . have you shot anything that is sharp. . . this is a very heavy lens and requires a bit of expertise to handle. . . . let's eliminate the obvious before jumping to conclusions about the lens. . . . my email address is bobglicksmith@me.com. . . send me an email and I'll be glad to setup a time to talk with you . . . . bgs.

Is the camera constantly trying to focus? The only motor I can think of is the one that moves the lens. Try it standing in a stationary position filming or photographing something that is not moving - like a tree trunk. If you don't hear any sound because the lens doesn't have to move to refocus, then I would guess it is the lens motor. I didn't like this camera personally and ended up returning it.

Yes, it does. I've contacted Sigma customer support regarding this issues and they assured that it's a "by-design" behavior and there is nothing to worry about. It's the OS lens elements causing the rattle noise. You can see that the noise stops when you engage OS (by half pressing shutter release). I also checked out a few other similar lenses at a local camera store and they all had the same noise. Mine is for Nikon though.

My lens is very smooth & quiet. We did have an issue with dirt inside the elements of the first lens and had to get a replacement. I suspect their manufacturing is not 100%

Haven't had that problem. The manual just says turn the camera off and check the connection. I'd worry that the lens electronics were damaged.

yes, the camera is supposed to this. i think this is a sound coming from the lens shutting, and cannot be turned off, i looked for it in settings..

well, i got the camera....was in loosely packed condition but intact. i took some shots after charging the battery. The auto-focus makes quite audible noise while focussing. However, the pictures are clear if you know how to work with settings.

Like everyone else said, it's not silent; you will hear the lens mechanism - while focusing. I wouldn't call it "noisy"; it has certain mechanical gears and screws that move big pieces of glass (read: somewhat heavy) - but it is not distracting, normal. When my mind is "in the frame/on the subject" (read: far away from the camera), i don't notice it at all. Manual focus is silent. It is a good zoom lens - judging by IQ.

You have disengaged the Auto Focus on your camera? The pin motor might still be engaged. Pushing it could do significant damage to the lens and the camera.

It is not the lens covers rattling, it is the optical element unit inside, could be because of the image stabilization mechanism as Vincent stated, but whatever the part is, I find it impossible to believe that this the way a major manufacturer like Canon designed it. Probably the latch designed to hold it when powered off is broken and not grabbing it. That said I don
