No, that's email from Zeiss and they said that about specific product when I called to clarify.
Well, if it's not written, then it's not a warranty exclusion/inclusion. It's not exactly rocket science. And nowhere have you shown that Zeiss specified the use of Zeiss-only products in their e-mail to you or in their literature. The hole is getting deep, so maybe it's time for you to stop digging LOL. After all, everyone here except you have grasped -- and understood -- this.
