O.K. Lets clear this up.
The changes to the Victory 8x40 & 10x40 binoculars are:
Strap holders were changed which makes them more user friendly to hold, (other peoples comments).
The Dioptre adjustment was improved. The rubber armouring is improved. Stray light was reduced to new levels, this is why the report in BVD suggested a change in optics.
Leif mentions the plastic around the eyepiece; Zeiss binoculars are manufactured with high eyepoint eyepieces, which makes them suitable for spectacle and non spectacle wearers, so it would be wrong to manufacture a binocular which could damage spectacles.
I admit to having an interest, but the fact is the Victory binoculars have a transmission of 90% +, which is higher than a number of competitors.
The Victory 10x40 BT* replaced the older 10x40 BGAT* Dialyt, because the Victory binocular uses a different prism system which in turn gives a higher transmission result.
