Mike,
I've only spent a $1,000 for binoculars once, that was for a Nikon 10x42 HGL, which I didn't like, the original version cost less and had better optics, IMO; however, if I had $1599 to spend on optics, the only binoculars I would pay that much for would be a late model Zeiss 15x60 BGA, which are still in high demand in the second-hand market and sell for about that much in VG to excellent condition. I would use them for stargazing, long distance birding, and for wildlife observation, so I'd get a lot of use out of them.
Why did Zeiss discontinue the 15x60 BGA 10 years ago, but keep the 7x50 BGA with IF EPs. If anything, I would think the 15x60 would be a better seller.
Although a Zeiss porro revival is probably about as likely as me hitting the Mega Millions lottery, I'm sure I'm not alone in wanting to see the 15x60 BGA resurrected. Just about everybody on the Cloudy Nights binocular forum (amateur astronomy Website) would like one. If Zeiss could make them waterproof, I think they would also be a good seller with hunters.
