    Hi there

    I've just bought a slightly used OM-D with 12-50mm kit lens, and overall I'm very happy with it. However, I noticed that the kit lens, when turned upside-down and back again makes a clunking noise.

    I know OIS lenses sometimes clunk when moved about, but this lens does not have OIS.

    I happened to have another copy of the 12-50mm lens available, and it does not exhibit this noise, which is really the only reason I suspect an abnormality.

    The lens works fine and performs well optically when connected to the camera.

    Does anyone else with this lens hear this clunking noise? Reason to worry?

    I've attached a recording of the noise - hopefully it's audible enough - might need some headphones.

    Thanks for any tips

    haha thanks

    Posted on e-group and dpreview regarding the issue and there are lots of others that notice it. Lens clunk in addition to sensor clunk when powering off =)

    It has linear drive focusing doesn't it? Same as my Sigma 30/2.8. That rattles too when it's not got power and you tip it back and forth. As I understand it, the focusing element is held in place and moved by electromagnets, so without power it rattles around a bit. No clue why you would hear it with one sample of the lens but not as you claim, with another.

    Just double checked the other copy of the lens.

    When I shift the other copy of the lens up and down, there is definitely something changing positions internally, but there is no pronounced 'clunk'

    I'll give mine the clunk test if I ever receive it :rolleyes:

    Mine have that "clunking" sound if that's what you refer to.

    Usually this comes from the EM5; the sensor is designed to float free, and when on is held in place by magnetism...when switched off the sensor will fall in the direction of gravity, and will clunk...changing the orientation of the camera will cause the sensor to fall again.

    Did you try holding each lens on its own (without being attached to the camera) to see if the noise is coming from the lens or the camera? Try holding the camera on it's own (no lens attached) and switch the camera on and then off...do you hear the noise you describe?

    I think it's either from the camera (normal) or the lens resetting (also nrmal). Why is one lens louder than the other? Maybe one of the parts are different, or different firmware. Maybe the lens was in a different focus position thereby making more noise to park it. Digital cameras and lenses make noises. Normal. Relax and enjoy.

    Definitely coming from the lens. The sensor also clunks when powering off as well. I've decided to relax since others have noticed the noise too.
