Looking at the Zeiss website I came across this recently posted graphic (download the pdf for a more legible version)
It's from: https://www.zeiss.com/sports-optics/en_de/hunting/service---support/download-centre/downloads.html
One interesting aspect is the distinction made between the glass types in the different product lines
And it specifically indicates that Schott HT glass is used in both the SF and HT lines
