Default Purple on the edges?

I am wondering about the color problem with the flower shot. Some of them came out with purple on the edges and I don't know why. I know it is out of focus and all, but that should not have caused the coloring should it?

It is call PF or purple fringe, it a CA a distortion form the lens. What camera are you shooting?

It is a K/M maxxum 7D with tamron AF aspherical LD 28-200mm 1:3.8-5.6 ( it also has a HOYA SKYLIGHT (1b), AND A HOYA pl-cir, AND a HOYA CS filter. I got the lens as is with the camera and really don't know what all that stuff on it is... YET... Thanks

I would remove the filter to see if it helps out a little if you shoot the photos with any one. But no lens is perfect, and some produce more PF then others.

Chromatic Aberration is a characteristic of all lenses, caused because the different wavelengths of light focus at different places. It is most prominent at the outside edges of the picture. Most photo lenses are corrected for it with some better than others.
By having three filters in front of your lens, you are adding three new pieces of glass to potentially increase the CA. The first thing to try is to re-take the shot with the filters off, to see the difference. If you find you need a filter for a shot, the fewer, the better. I would only use the one I needed for the effect I was trying to achieve.

Thanks Brian, Seriously I had no idea that they were on there when I took the shot. You can tell by just that I was totaly clueless when I recieved the thing, as a matter of fact I did not notice them until today when I went to look at what lens I used for the shot DUHH, I feel a little dense that I did not know...Well I learn every day, Thanks for the help and info.
