Yes, 10x40 Swarovski Habicht, porro prisms, bought new in Austria in 1982. Still superb. Had a pair of Leica 10x40 roof prisms, didn't like them near as much, so they went down the road and I've stuck w/ the old Swaros.

When I want really light weight, I default to some older Nikon Nippon Kogaku 8x30s from the late 60s. Also superb resolution, and very compact and light. I also really like a similar pair of Nippon Kogaku/Nikon 9x35s of about the same vintage. Great glass, when you can find them, at great prices.
