On the FA*24 The colours split towards the corners both softening and distorting the image. I'm sure it happens more at particular apertures but after some atrocious results I've pretty much packed it away. I suppose it's far better than most people generally experience given that the majority use zooms but relative to the 31LTD for instance it's poor. The 31mm in the same situation ie a panoramic shot in the scrub at wide aperture will render remote branches sharp and CA free right to the corners of the frame. I'll have to dig up some of my poor FA*24 shots as examples.
