40-150mm M.Zuiko blows on me!

Bought one yesterday with a massive discount (check here for details) and I had to try it for defects before it went wrapping and Xmas tree undering.

First I though I was going nuts, but then after a few fast zoom-in-out cycles there was zero doubt that I was feeling some wind on my EVF eye. If you do a fast zoom out, as the lens barrel compresses towards the camera, it blows air into my GH2 camera body and that air escapes through the EVF.

I know this is just physics, but I wonder how much dust ends up falling into the sensor on account of these funny games...

There's an argument for prime lovers.
