After discussions about it on this forum I measured a newer sample in may 2016 and in that  sample the transmission at 550 nm is 88,7% still quite a bit below the Swarovski Habicht 8x30 and the Zeiss Victory HT 8x42, which have a 95-96%transmission at that wavelength and, if your eyes are allright you should be able to observe that difference as a difference in brightness. That is extensively discussed on this forum, but if it is still confusing I will add that information.Gijs van Ginkel</blockquote>
