I spent a lot of years in Germany and they tend to be more single-sport focused than Americans. They don't buy a bass boat, a quad, a jet ski and all the other goodies we spend money on. Within their one sport, they tend to buy the best available. I had an opportunity to compare my East German (yeah, it's been a while) Zeiss binos with the Forester's Swarowskis. I was pretty impressed with the optical performance of my big Zeiss (the mechanics were a bit loose)but just at last shooting light, those 10x42 Swarowskis made my 8x50 glasses look shabby. Do I own Swarowskis now? No, but wish I could afford some.
When I bought new glass recently, I first narrowed the field down to those which would close enough to fit my very small interpupilary distance. My eyes are VERY close together. Then I looked for optical quality and mechanical stability (some of them were pretty easy to knock out of focus by just pressing them against my eye brows). Lastly I looked at price. Sadly, I had to put a couple back just because of price and wound up with some Nikon X glasses. Super glass for the price. Maybe some day Michigan will draw my number in the lottery and Swarowski here I come!
'Till then, I'm very happy with what I have.
