    Is that normal?
    When f is above 1.4, the lens make noise which is noticeable when the GX7 is in silent mode. However, when f= 1.4, I don't near that noise.

    It is the aperture stopping down. At f/1.4 it doesn't need to close any. It is perfectly to hear a slight whirring sound.

    Yup it's normal unfortunately. I've tried 2 PL 25s to check too. You can see the aperture close when it makes the noise. At least it doesn't constantly make that noise as it does in some olympus cameras.
