Great Glass. I gave 4 instead of 5 because I?m not a huge fan of the outer material. These are also my first Leupold optics so it could just take some getting used too. I would definitely buy again

I'm still trying to figure out how they did it. I have two other sets of binoculars and both of them have a setting for one eye and then you focus with the center adjustment. With this set its just the middle roller and it focuses both eyes so fast that I am in disbelief. The clarity is unmatched compared to my Vortex and Nikons. These are unreal!!! Even at dusk I can see better than my bare eyes. Everything is so sharp. Now I know how an eagle feels because I feel like eagle eye while looking through these. I might as well through my other two pair in the trash.

These optics are truly impressive. The clarity is far above the BX-2s. I went up to the 50mm and have noticed a different at twilight. May not be something you want to pack all the time for deer but if you are glassing then it will feel more comfortable and give you longer to view. If I had to have 1 set of optics these would be them. great quality for the price, excellent light visibility, and great clarity.

Very good for being able to see what you want to see, hunting or casual use. You can definitely see the game far before you have to be ready to shoot.

Bought these on a Tuesday, took them on a South Carolina hunt on Wednesday. Five minutes left in the hunt and I used these to glass one last time. I saw a buck that I would not have seen without them. Was able to pick up the deer in my scope and dropped him where he stood. I would not have taken this deer without these binoculars! Great product!!
