    I just purchased the Panasonic 25mm f1.4 a few days ago. Really been enjoying it, but tonight at a restaurant I took a few pictures and noticed this banding. Is this a problem with my lens?

    1st image with banding: 1/50 f1.4 iso1600
    2nd image it disappears: 1/8 f2.8 iso1600

    Using a Panasonic G5

    DMC-G5    ---    25mm    f/1.4    1/50s    ISO 1600
    DMC-G5    ---    25mm    f/2.8    1/8s    ISO 1600

    Were you using the electronic shutter? This can cause banding under certain lighting such as fluorescent and at certain shutter speeds. It's more noticeable on light, solid objects or backgrounds.

    Here are a couple of pics of a pad of paper under fluorescent lighting. They're ugly, but demonstrate the issue. Both are taken using electronic shutter on the GH3.

    This shot was with shutter speed 1/250 sec.

    DMC-GH3    ---    25mm    f/2.5    1/250s    ISO 200

    And this shot was at 1/60 sec. No lines.

    DMC-GH3    ---    25mm    f/5.0    1/60s    ISO 200

    Recompose so the object on the right is not in the frame. :)

    Thanks seadragon. The electronic shutter was the issue. Thanks for solving that problem.
