You can’t eliminate chromatic aberration with coatings, it’s a physical property of how the lens interacts with light. The only way to fix it is to adjust your lens types or materials. Zeiss’ current marketing seems to agree https://www.zeiss.com/consumer-products/us/nature-observatio...

Coatings are still very useful to reduce other lens artefacts though.

If you cut some wavelengths, you won't get their contribution to the distortions ;)
