  • HELP! Panasonic 20mm Light flare spikes

    I've only been using this Panasonic 20mm lens for 10 days bought from new. The other day I noticed that when bright lights are in the picture, the flares from the lights spread across the image making it unusable.

    And now when I point the camera at say a streetlight I get light spikes whereas before it was a suppressed glow.

    Is this a lens fault do you think. Tried wiping the lens with damp tissue and had no effect.

    If anyone has a 20mm attached to a gf1 do they get suppressed glow or spikes of light when they point to a light like a streetlight or a traffic light ?

    Do you have a filter fitted? And what apertures are you talking about?
    It's the image that's important, not the tools used to make it.

      There is no filter fitted. The aperture is f1.7 and I haven't used any other aperture on this lens

        In that case I'd suggest trying the lens on a different body to see if the results are the same.

          Only have the one Gf1 camera. Why would you think it was the body and not the lens ?

            I'll try to upload some before and after images to illustrate what I am talking about

              Testing the lens on a different body would help show if it was a reproducable problem with the lens.

                Three days a go I didn't have the problem with the lens.

                Do you have a 20mm attached to a gf1 David M ?

                  I don't have either body or lens. Try to post some sample shots. That may help people work out what's gone wrong. I take it you haven't dropped/banged either the body or lens before you saw the problem?

                    Could you post a sample of your problem.

                    The fact is shooting into any light is not without problems, and the effect you describe do not to me sound unusual depending on how bad they are.

                    The fact is digital is more prone to flare than film, I am not sure of the technical reasons. Secondly wider angles lenses them selves can be prone to flare add the two together and it can be a problem.
                    Always use a lens hood, although this will not help directly into a strong light.
                    I often shooting into the light add extra shade with my hand or cap (if I am wearing one) again this only helps if the strong light is at the very edges of the frame.
                    All this said there may be a fault which is why a sample shot would help readers to evaluate your problem.

                      Of course I haven't dropped or banged the camera.
                      David M, we seem to be getting nowhere and I have to make a decision about the lens.

                      Anyone else, who has a gf1 perhaps with the 20mm lens attached ?

                        The same streetlight at approximately the same time of night.
                        Also noticeable on traffic lights and headlights were before it was a glow.

                            I have a GF1 with 20mm and I don't experience these problems. I usually shoot in P,A or S modes.

                              The photos definitely look odd. Was there anything else in the frame, or were you only trying to take pictures of the light? What are the exposure settings? The light is very much overexposed, so this by itself could be the source of the problem. This does not look like your typical lens flare. If you can give some more information about the camera/exposure settings and the other photographic conditinons, we may be able to get to the bottom of the problem.
