    I'm new to GX7. Sorry if this has been covered, I did search around.

    I just put my PL 25mm f/1.4 on the camera and I'm shooting indoors in typical household lighting. When I half press for autofocus, I see the image dancing or wobble, like a very slight zoom in and zoom out.

    It seems that I am getting good focus but I haven't checked images on computer yet.

    Is this anything to be concerned about? Am I missing a setting or something? I thought it was IBS, but I disabled it and issue is still there.

    This does not happen with the kit 14-42 or the Lumix 45-175 on GX7 when shooting the same exact scene. Also does not happen with the 25mm on the GH3, so it's something with GX7 and the Panny Leica 25.

    I'm an idiot...camera was in AFC. Switching to AFS and no more wobble.

    Still, I haven't seen this with other lenses...

    Since the lens typically focuses at the max aperture, the DOF is much thinner than your other lenses, making the focus drift in afc more noticeable.
