I've been using an EP3 and just upgraded to the EM10. Yay! However, when using the 17mm and 14-42mm compact zoom on the EM10, there's a lot of noise from the lenses. I don't hear as much with those lenses on the EP3. Does anyone notice the noise? I took it to a repair shop and they said it's usual camera noise. A 2nd shop said the mic sounds like it's ON. Let me also explain that I had the camera in a padded lens case in my bicycle pannier with about 8 records inside, and my bike fell over on the pannier side. Therefore, I'm worried that the weighted impact may have damaged the lens, but it's odd that both lenses sound noisey. Any ideas?
