None of my lenses are coded except for the new WATE I received today. If you want to use IR filter you need to have the lens coded so it can take care of the cyan overcast. I seldom shoot indoor with fluorescent light so I don't care for the coding /IR filter use. The coding also help takes care of the vignette from very wide lenses which I have on my WATE. So there you go IMHO.
