B = High eyepoint eyepieces for eyeglass wearers

GA = Rubber armouring

WA = Wide angle eyepieces

T* = Proprietary multi layer coating (only used on German mfg. optics)

P* = Phase Correction Coating, all Zeiss Roof Prisms are Phase Coated

MC = Multicoatings (reserved for U.S.A. assembled products)

FL = Extra low dispersion fluoride ion glass

AOS = Advanced Optical System (light weight high resolution glass with NO lead or arsenic)

DR = Dual Reticles
C.F. = Center Focus
I.F. = Individual Focus
AK = Full Size Roof Prism

ABK = Abbe Koenig Prism w/ P* Phase Correction Coating

 

Some of these markings could mean up to $500.00 worth of difference in value on Zeiss products that have looked the same or similar over time.
