    Hi

    Question to other owners as my new lens makes this weird noise when moved around. Btw. it's not stabilisation or continuous autofocus (focus is switched to manual on the lens too)

    this is how it sounds (you need to crank up the volume microphone isn't close)


    Any idea what is it? is it normal?

    thanks
    Michal

    Mine mounted on my EM-1 makes a similar sound. No idea what it is but it doesn't sound malevolent to me.

    I suspect it is the floating lens elements that move for the internal AF.

    Thanks guys. I wasn't sure if it's normal for this lens.

    Mine does the same. Thought it was weird at first but got used to it quickly. Don't here it anymore.
