Re: New GX-7 with 20mm f1.7 II Kit lens - Sound from lens on startup

When powering on a camera with a lens connected, the camera will always test the lens. This is done by jogging the focus back and forth, and by adjusting the aperture. Both of these operations generate some noise. This is normal.

With the 20mm lens, you can even see the lens barrel move slightly as you power on the camera. This is the camera testing the focus function.

So it sounds like what you are seeing is completely normal.
