Thank you for that answer. It makes a lot of sense. When looking for Internet reviews of binoculars over the years, I discovered that there are a lot more bird-watchers than I would have suspected, and they certainly appear to spend a lot of money on glass. It seems that they buy glass like hunters/shooters buy firearms.

The funny thing is, I don't personally know any dedicated bird-watchers, and I don't believe I ever ran into one while in the outdoors. They must spend a lot of money on camo, too....
