I meant to say:

At first I understood that 6 bit coding would be necessary only on lenses longer than 28mm to reduce unwanted vignetting and that other than that function, the codiing only added exif data. Then it seemed that the 6 bit coding could also reduce or eliminate cyan in the corners of images shot with the IR filter, but, again, I thought this was only an issue with lenses SHORTER than 28mm.

I hope the question is now clearer . . .
