Weird buzzing noise coming from new ex1

[brian leahy]

I'm getting a low buzzing noise from my one month old ex1, the noise sounds like a working computer processor. It makes this low buzzing noise when zooming and focusing and also to a lesser extent when you move the camera but is silent when the camera is still, the internal mics pick up this faint sound, you can see it on the levels. Is this normal, i don't have access to another ex1 to compare it to. in a quite room you can hear the buzzing easily.

Thanks

your description sounds like what i hear on my Ex1 so I think its normal. I haven't ever picked it up on mic though. Ill have to check for it next time I use the camera.
