You may be seeming sensor bloom not CA as CA is pretty much able to be eliminated using the ACR lens tab adjustment tool and it only takes a few seconds (hint, set the image view to 100% or more, head for an image corner and hold the ALT key down whilst adjusting the either of the sliders). Blooming can be exacerbated by applying excessive sharpening at the RAW conversion phase. > In other words, you'd find worse CA at the corners > since a FF sensor is using the entire image circle > instead of the so called, "sweet spot" utilized by the > smaller sensors?
