I have owned the Bx4 Pro Guide 12 x 50 for a couple years now and I am still very happy with the purchase. This guy is right, for the money these are definetly some of the best binos on the market. The clarity is amazing, color is great. I use these for birding, among other things, and they are just perfect. I tried a pair of swarovski's and yes, of course they are amazing - but honestly these are just as good and like 1/3 of the price. They might not have the luxury look of the swaro's but the Lupolds are a great piece of glass. You can't go wrong with these in my opinion.
So here's a question...your title of this video is for "10x42" but you state repeatedly you are reviewing a "12x50" binocular. Get your story straight.
