Yes, some years ago I did some test on Zuikos and found a single coated
300/4.5 has very visible chromatic aberration on bright light bulb, I just
though the sample I had was having some problem or the SC glasses was not
that good. Recently I took some shoot with my 300/4.5 MC and found the edges
of bright white area has similar problem but at the same time my Zuiko 500
was free from any chroma.
