Pink and green outline at DVinfo.net

Im not sure if this is just me but when I review my footage alot of the time i get a green or a pink outline on people, objects or windows. What causes it and how can i fix it.
I usually shoot interlaced because I often cover alot of fast moving action,could this be the problem. Am I using the wrong shutter speed?

Hi Marko,

Are you shooting with a conversion lens or filter on? It sounds like chromatic aberration.

Definitely sounds like CA. Even without a lens adapter, it can appear any time you have highly contrasting items in the image. Typically they'll show up toward the left and right sides of the image.

Don't fret. It's not unique to the A1. I've seen it in broadcast programs that were shot without the benefit of controlled lighting.
