If considering buying Leupold brand Binoculars I can ONLY recommend buying their BX5s. I own every single model BX1 BX2 BX3 BX4 and BX5 and only the BX5 is acceptable to my eyes the rest are all junk. Better off buying Athlon Midas UHD Gen 2s or better yet the dirt cheap ScoopX UHDs. Frustrating to see not as crisp image quality with excessive chromatic aberration looking through BX4s and below models. I do appreciate all 3 models of my the BX1 Porro Prism 6x 8x 10x Binoculars though which don't appear to have such offensive chromatic aberration. They're at least as clear as my Kowa YF Porro Prism and Nikon Action Extreme EXs.
I already looked through so many different Binoculars already so man, the BX4s in 12x50 really are a major disappointment to my own my eyes especially when compared side by with way cheaper priced ones including dirt cheap generics.
I'm SO tempted to buy the $329 2023 new improved updated Japan made green Burris Signature HD 12x50s currently on sale on Amazon but I'd be pretty pissed if they aren't clearer than AT LEAST my CHINESE Athlon Midas UHDs.
I'd wait for the SIG Zulu 10s to go on sale as SIGs usually do just to move inventory like they did at Midway USA ($500-600 SIG Zulu 9s) before spending close to $700 on a BX4 Gen 2 because this is next level Vortex Razor UHD beating glass on the cusp of tier 1 Alpha glass.
