A few days ago there was a topic about the way different manufacturers
indicate a coated lens in the lens ring specs. There was an
interesting story between Rollei and Carl Zeiss Oberkochen about this
topic. Carl Zeiss was providing lenses for the Rollei SL 35 with the
multicoating "T*" treatment from the beginning, however they did not
indicate that the lenses were multicoated; in the other hand the
Japanese lenses had multicolor letters and massive propaganda to
indicate the multicoating treatment for them. Rollei became
"desperate" for this reason because they wanted a strong market
presence for the SL 35 and then they pressed Carl Zeiss to find a
solution for the "unknown" multicoated treatment for the SL 35
lenses.There was an initial agreement, lenses made by Rollei under CZ
license would be engraved "Rollei HFT" (red letters meaning High
Fidelity transfer, the "T*" process that Rollei could use under their
own name "HFT") and the CZ lenses made by Carl Zeiss would be engraved
"Carl Zeiss HFT", this is the reason you can find today lenses for the
SL 35 cameras engraved "Carl Zeiss HFT", it also happened with some
lenses for the SL 66 and the Planar made by Carl Zeiss for the
Rolleiflex F Platinum 1984/85 special edition was also engraved "Carl
Zeiss HFT" .
In the Photokina 1972 Rollei introduced seven new lenses for the SL 35
using "HFT" red letters for the first time.-
