An alarming degree of colour fringing (Lumix GX1)

[DCUR]

Thinking to advance at last into digital capture I bought a Lumix GX1 M4/3 body and paired it with a Zuiko M4/3 45mm lens. After all, that's a point of the system, isn't it, that you can interchange components having the same M4/3 fitting?

Either green or red colour fringing is often rampantly present where such as tree branches or utility wires are set against a brighter sky. I think it varies with whether the branches etc are at the plane of sharpest focus.

I don't have access to any other M4/3 system bodies or lenses to check out different combinations for this effect. It occurs in full-res shots across RAW and JPG files. If I import RAW into PS CS the available chromatic aberration sliders are not sufficient to control it.

I'm not being hypercritical - the effect really is marked. And I hope that no-one is going to suggest that I retouch every current and future image that is so afflicted! Life's far too short.

It would be interesting to come across someone else with the same problem from some combination of the same equipment and compare notes, rather than hear merely generic observations. I seem to have bought a pile of junk.

Follow-up.

After some more test shots today it seems that it only occurs at f2.8 and f2 and disappears at f4.5. I wonder if the effect would be the same paired with another camera body - say an M4/3 Olympus, or is it a lens-only issue?

Try here, huge following of people with that camera using a wide variety of lens.

I would check there, but I think i have read several threads about the Pany making corrections in camera, but only for their lens. The camera won't or can't correct for Oly, or zeiss or any other "off" brand lens.

Thanks so much for that, Ann, I'll follow that up. I had been wondering if I should be better off with an Olympus body in this instance ... hard to find these things out, however I HAVE raised a ticket with Olympus uk support ...

I have really fallen in love with 4/3 system. Have had several pen cameras and recently I got the OMD-EM5 and it is so much fun.

My real test is going to be taking it up to Boston and Washington at the end of the month; leaving the D700 at home.

I do get a panic attack on occasion about this decision, but the more images i see from this camera along with my own testing is reassuring. I have only one non-oly lens and that is a Zeiss 50mm 1.4 that i got an adapter for, and the first shot was just inside on a dark night the day the adapter arrived. I need to do some serious shooting with it to come to any serious conclusion (the lens, not the camera).

I have been thinking about the pany 25mm , that is why I remember a bit about the fringing problems .

Good luck
