Hi
I made shots in the above settings and noticed a very visible CA. I have tried the 5.6 and 8F but with almost no result (the CA reduced but still notisible). So is there any way to remove it - software for this, or I am "doomed" to this CA when using 12x. Maybe I expect too much from the Licka lens but on my brother FZ5 the CA is much less than in FZ20 (or maybe only I see the difference between them).
To be hoest if the picture is 50% showed no my monitor CA is not a problem (72ppi * 2 ~ 150 dpi when printig which is good - or I calculate wrong?)

How do you fight the CA?

Can you post the picture? Maybe it would be easier to figure out the solution after seeing it. Jim

6mm - F2.8 1/10s - iso 80 - out of focus (low light - in my room 6x3.5x2.6m with 2 100W philips lamps and no flash)

Whats wrong with my camera?

That looks strange, normally you might get some CA if the picture has some strong backlighting but yours doesn't ! I would try some different settings and try to duplicate the picture. I also would turn the IS on to mode 2 and try using a flash if it's a low light situation as your pictures appear to be. Also try using the automatic P mode . See if these things make a difference.

10x for the advice I will try but how turning on the stabilization will solve the problem - I was used tripod for the shots. And here is another shot - outdoor
100% crop - 72mm, F4, 1/160, mode2, P mode

How do you fight the CA?
CA shows up when the focus is not close to or perfect. I never have CA when shooting F5 at ISO 80. Your pictures are not sharp. When you shoot on a tripod OIS= off. Yes, even at 100% crop your picture should have detail. This was shot with a 4mp FZ10 and how much crop would you call this?
