Hello- I've seen this before on low quality cameras, but does anyone know what causes this blue "halo" around white objects in this frame and how to resolve it (in camera)?

Thank you.

Halation? I think it's fringing from the high contrast between the hard bright white and the black BG.

That's a good thought. Thank you. The guy is using a new camera...previous camera didn't have this problem with the same set up (contrast).

That is called chromatic aberration, it is a physical limitation of a lens. Higher end cameras that employ more expensive lenses and chromatic aberration correction software will have less of it.

You will get CA when:

-You are using a long lens (zooming in a lot)
-High contrast
-low cost gear

Thanks Emre. I guess I just didn't believe that was still possible with cameras today! Appreciate your response.
