Hi Mike 

The T* is a trade mark for Zeiss lenses with multi coating, anti reflex
coating. What I now  there are no difference in quality between Zeiss zoom
10-100 mm T2 and 11-110 mm T2.2. The later covers super-16.
The OpTex conversion of the 10-100 mm T2 lens to super-16 12-120 mm T2.4
have a 1.2x extender added on the rear lens element. As soon as your adding
extra lens element you start loosing optical quality, but I can´t tell you
how much, let say 20% ?? or less in resolution.
