    Does anyone else have the following issue with the E-P3 (or other camera using the first generation Micro Four Thirds sensors)?

    As can be seen, the lamps have a sort of halo around them. This was taken with the E-P3, the Panasonic 25mm f/1.4 lens on 1250 ISO. They do look rather odd - what might be causing them?

    Flare from a lens filter?

    Hmm - no filter was being used, so it can't be that; and I don't think that it's a lens issue, either, as the distinct rings around the light source don't seem to be a natural optical artefact.

    f/1.4 - the light was low.

    Ahh, I see, thank you! I shall keep an eye out for the Olympus 17mm f/1.8 when it is released, then...

    Would stopping down help?

    Stopping down definitely helps. See the examples from the second link. By ƒ/2.8 the OOF area is normal.

    The second link also shows the concentric variation in brightness that are apparently caused by either the machining of the aspheric element and/or by the glues holding elements together.

    I have had a few flare issues. These two fails were taken with P14 2.5 on a E-PL2

    The first one is f2.5 & the second f14

    f/14 or f/1.4?
     
  12. Point light sources rarely look good when shot at a lens' maximum aperture.

    Second picture looks like the notorious red spot flare of EPL-2 due to the thin AA Filter but usually it happen when you shoot to the sun.

    FYI: E-PL2 red dot problem

    As he already mentioned the 14mm lens. It could only be f/14 as the Panny 14mm has a max aperture of f/2.5.

    Yes.. f14 on the 14mm. The f2.5 shot caught me a little by surprise, though I had heard of the redspot issue at the time.

    Here's an example of normal lens flare with Panasonic (there, I wrote it properly :biggrin:) 20mm @ f1.7 with E-P1, ISO1000 when I was testing my flash positioning before wedding. I don't remember if I was using a filter in this shot below. But my "twenty" definitely does that kind of flare wide open even without the filter. To be honest, I kind of like the effect usually.

    The E-P3 camera produce odd green halos?
