    Is the Pana 20 f1.7 really noisy during focusing? Mine vibrates and makes very loud noises while focusing.

    Yep, that's normal, every new owner is surprised to say the least about how the lens makes itself heard during focussing and taking its time for it as well. One good thing is, I got mine pretty much the day it was available in Europe and it hasn't become worse.

    I bought mine second hand, so I was naturally double worried, despite reading about how noisy it is, I still got a little scared! Perhaps I was too used to the near-silent 14-45mm.

    It makes a bit of noise, especially in low light when it starts hunting.

    If you tried 4/3 lens on m4/3 you will be happy with your 20f1.7 :D

    I have tried three copies.
    All three were noisy but not at the same level.
    One was ridiculously noisy with some vibrations.
    The other two were acceptable but still noisier than what I am used to from my previous experiences with Canon and Olympus lenses.

    It is normal, and apparently not consistent. Some people have reported less noise on Panny bodies.

    Thanks for the replies. Mine is so loud that people pick up their head from 5 feet away when you focus. It vibrates enough that you can feel it when you hold the camera in your hand. The lens has been this way since I got it as part of the GF-1 kit in 2009. It sounds like maybe I should send it in for servicing.
