Alex, I guess that my point is this. The same imaging train, whatever the case (same Nikkor lens on both Nikon and Canon body) or the SCT - the Nikons I have always produce the purple flare - in every situation. The Canons do not (350D, 450D, 40D and 5D-II). I'm not saying that the Canon doesn't produce chromatic aberrations, of course they do, but not NEARLY to the same extent as all of my Nikon bodies.
