CarlosALL CZ lenses made after 1970, with a very few special exceptions, were multi-coated. Customers, however, had to PAY to have the lenses marked with the "T*". Rollei was simply too damned cheap to want to pay the freight. Had they paid -- as, for instance, did Hasselblad and Arri -- their lenses would have been so marked.
Rolleiflex always claimed that HFT was a proprietary mix and was different than the T* coating. Zeiss has always sneered at this claim.
