    I noticed recently my 20mm started buzzing when autofocusing. Anyone else have similar problems? I bought the lens from another user here so I don't have a receipt. Do I need to get a receipt before I call up Panasonic?

    Was it in bright light? Sometimes the shutter opens and closes

    It was in dim light, only when it's focusing. I've had it for a few weeks now, this is the first time it's come up.

    I've noticed noise when recording a movie. That's how I found out not to use this lens for movies :)

    This lens makes a noise when focusing. Is it possible that you are only noticing it now, or is it definitely something new?

    The noise is definitely a lot louder. I recorded a video to capture the sound and realized the video's also getting a clicking noise. I think that might be might be me tapping on the screen trying to get it to focus. I'll try and record a second one just to confirm.

    Here is another. I can't tell if I'm crazy or not. The auto-focus noise is 3 time louder when it's not in video mode. I wish I had another camera so I could record it in action.

    I compared it to the 14-45mm and 14mm and those are both much quieter than this.

    I forgot Windows had a "Sound Recorder" and I have a mic. Would anyone mind comparing this to theirs before I send it out? Just a sound file:

    Hard to judge how loud it is by just an audio clip, but I can hear it clearly an arm's length away.

    Same thing here

    I just gotten a 2nd hand Panny 20mm, and I have the same sound/vibration problems mentioned above. Is this normal? Im worried that I may have gotten a defective lens or it got damaged en route. Sorry to resurrect a dead thread.

    Mine sounds the same as in the vids. I had to put my ear to the camera to hear it though. Mine is brand new. I think its normal.

    Then is it normal to feel vibrations through my GF1 body when it autofocuses? I feel like I have an electric drill now.
