Re: Leica Binocs, 8, 10, or 12x50 BNs
The bino adapter for the Leicas stays attached to my tripod head qick detach piece and also straps down my Leopold 12-40x60 spotter very fast so it's all I use for both, kind of worked out great for me. It takes about 5-10 seconds to switch between the two.
My father likes the 10x50's too but he hunts out of a buggy and doesn't do much walking anymore. Really I used a pair at the range a couple of months back and swore they were 10x42 but turned out they were 10x50, not much difference but I never had them around my neck for a while either.
Good luck. Don't cheat yourself which ever ou go with, grab a tripod adapter for it too. The Leica adapter will work on about any of them you choose if an adapter isn't offered for your model.
