Have your friends with the high dollar optics to compare thiers with your docters. I think they will find very little difference in thier expensive binos and you mid priced ones.....even if they don't admit it

PS Optolyth is another german brand that is not well known and is awfully good. I have a pair of Optolyth alpen 10x50 and they are every bit as good as Zeiss classics and the older SL swaros
