does this lens rattle when you shake it? the lens cap is not attached to 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.

Yes a very little but I was told that's the anti shake part of the lens,It doesn't bother me and the lens takes great pictures

When disconnected or unpowered, the optical stabilization elements do shake/rattle inside of the lens. When mounted to the camera and the camera is turned on the shaking/rattling ceases. This is the only lens I've encountered that has this "feature."

Yes. it does so in mine also. I think it is when you turn it off or you deactivate the AF that the lens probably detaches something inside.

I have never had any rattling issue. My copy is very solid, plus the lock keeps it from "zoom creeping", although that has never been an issue either because the zoom ring is fairly tight to turn.

Actually. Yes it does a bit. But it's not terrible especially when extended to 50mm.

I have no issues at all with my lense, the case is thin, but the lense never touches the surface it is sitting on. The case is a little smoother than others Ive used, which equates to being a little harder to grip, but it was very easy for me to get used to. I remain very happy with this case.

Yeah there is a very little wiggle sound. If that's what you're hearing when you shake the lens that's fine. No need to worry! I have it on mine also and it works perfectly fine.

No. I have not heard it rattle at all. The way it fits onto my car's (Honda Fit) headrest is pretty tight so there is no room for it to move and rattle.

Hi. When the camera is switched off or the lens detached, the motor is disengaged so the focus elements and/or aperture rattle around. I had one of these for a while, and the 30mm version and both did the same thing. I never got the sense that anything was in danger of breaking and as soon as you turn the power on everything snaps into place.

No, we have never encountered this issue. We use the camera frequently for road and mountain biking. If you move/shake the camera while just holding it in hand I would say may be a manufacturing issue, I would return and request replacement. We have not had any issue with this camera and love it!

Mine is not silent but it doesn't rattle. I can try and grab a video tomorrow.

Hi Gilbert. Thank you for your question. The lens should be mounted on the camera only after you zoom the lens first. Also, you must use a tripod or some sort of stability to prevent shake. Lastly, the image should be of something or someone not in motion. Thank you

I've been using this lens for several months now and I do not hear such a sound as described. You should probably have it checked out.

Yes, this is typical of this lens. Once it is energized the rattle disappears.

I just shook mine and there was no rattle. Sorry but I suspect something is amis with yours.

It will scratch but it takes a beating before it does. The lens is apparently coated with a scratch resistant coating and it has a cover on it. hope this helps.

If the lens is mounted and the camera is "On" then you may be hearing the aperture. This is normal. If the lens isn't mounted and you can hear a clunk if you move it this would not be normal.

Its going to rattle when you put it on the gun. Even back in the day when we put it on the M16A1 it rattled. Like the M16 didnt rattle enough on its own

Mine has a soft rattling sound when I shake it firmly (I just checked)--and it's brand new, working perfectly.

No mine does not rattle or anything. Mine feels solid. I'm wondering if the adhesive that holds the battery has come loose on yours.

As noted by G. Harwell & T. Steely, shake reduction is built-in the lens (OIS) for zoom lenses only. Prime lenses do not have it- and in my opinion - do not need it.N. L. Marin
