    The first time I tried to use my Olympus M.Zuiko 12mm lens, I touched the screen to have it focus, and I got this error:
    The app was in auto-focus mode, and the lens doesn't have an AF/MF switch like the DJI 15mm lens does. But the lens was, in fact, in manual-focus mode. As it turns out, the Olympus M.Zuiko lenses have a "snap ring" that changes between manual focus and auto focus modes.

    When the focus ring is snapped away from the front of the lens, it reveals a distance scale, indicating that it is in manual-focus mode:

    And when the focus ring is snapped toward the front of the lens, it covers the distance scale, indicating that it is in auto-focus mode:

    So I snapped the ring toward the lens, putting it in auto-focus mode. I was then able to focus by touching on the screen as expected.

    AFAIK, that is only a characteristic of the M.Zuiko 17 mm lens. My M.Zuiko 12 mm f/2 has a AF/MF switch. I'm getting the 25 mm Oly tomorrow, so I will be sure to check.

    My Olympus M.Zuiko 12mm does not have an AF/MF switch; it has this snap ring. As does my 17mm. My 25mm and 45mm have neither.

    Gaak! You're right! I just checked. I confused it with the DJI 15 mm lens, which does have a AF/MF switch (which is ironic, in a way, since you can turn it on or off in the app).

    Thanks for the heads up. I suppose all M.Zuikos are like this?

    have you tested 17 and 25mm on the x5 yet? is it workable?
    I am planning on getting the x5/x5r but am held back by the limited 3 lenses

    I tried the 17mm lens. Without an ND filter, it caused the gimbal motors to vibrate and make a lot of noise. With the B+W 0.9 (3-stop) ND filter, the vibration and sound went away.

    I haven't tried the 25mm lens; I think the 17mm lens is too narrow already!
