Any Zeiss/Optics experts out there? I'm interested to know when T* coating appeared on Zeiss lenses, and what is supposed to be so special about it? obviously they had coated lenses before, single then multi coated, and then they must have branded this multi coating T* - but when was this (1978? 1982?) and what does it amount to? I've heard some hassleblad experts say the multi coated chrome lenses were the ultimate from Zeiss (rather than the later black finish ones). Is there any basis for this, or is is just Quality Control reaching its peak in the late 70's and going down slightly in the 80's? t.i.a.
