I'm really interested to know what software can deal with chroma, some years
ago people say Panorama Tool can do this and even provided a formula for
correcting E-10's barrel distortion and chroma. Finally the distortion is
correction but never the chroma, I suddenly remember there are color shift
only on the bright white light area how can they correct this without
affecting the other normal area around them?
The problem of C*non lens on full frame is not only vignetting and chroma,
the resolution is also seriously affected, I have seen their own test sample
with the 16-35/2.8 on 1D MKII, they edges resolution was really suffered and
it was not even FF.
