I will update this review over the months as I gain hours behind the glass. I am a full purchasing consumer. This review is not based on a free review sample. I am not getting any compensation from the retailer or manufacturer for posting this review Early Impressions, [7/4/20] First off, the seller sent me an 8x42 model instead of the 10x42. Thats alright personally for me since the 8x42 turned out to be preferable for me. Had this actually been the 10x42, there's a good chance I would have returned it anyways for the 8x. So take this for what its worth. There are several options in the ~$500 ball park. Several of the YT reviewers for all of these models mentioned how well these scale up with more $$ units. Hawke frontier ED Nikon monarch 7 Zeiss terra ED Vortex Viper HD Many Steiner models I eventually went with these leupold BX-4. What sold me was the locking diopter and eye relief. I will be using these actively as a trail hiker & backpacker. They will be slung around my neck/shoulder and no doubt getting bumped around a bit or at least swinging around. So I wanted something with no chance of getting bumped out of adjustment. I could set and forget. The archery / bow hunting forums and YT reviewers kept mentioning these. Several comments how quickly the operator could acquire a clear sight picture, identify game / foliage differences even in dark shadows, set the binos down, re-acquire sight picture, load, draw and fire. I am not into archery or hunting. I have range-shot archery, small caliber rifles and shotgun clays. I am experienced enough to know that sight picture is everything in shooting sports. So I think I was able to use that user feedback and find a product that fits my needs. A lot of reviews also mentioned how much better, brighter, clearer the BX-4 optics are over the BX-1/2/3. Basically $$ well spent without going hog wild on the $1000+ BX-5. Many positive comments on how the BX-4 fills the price-performance gap between the $250 and $1000. So far I am happy with my purchase. I am clearly seeing new things on my hikes. Everything from wildlfe to landscape, so bright, clear and vivid. Just like the archery forums said Its like looking deep INTO shadows and dark areas and seeing into them. Its like seeing into dark shadowy objects with with a good quality flashlight. I would not recommend a 42mm objective if you have size and weight limitations for your load out. Its ~1.5 pounds (663 grams) of glass, metal and plastic. IMHO its Perfectly OK for day hikes. For multi-day section, or through hikes I would go with a much smaller/lighter option.... something in the 8x26 range like a Nikon trailblazer.

My husband had these on his wishlist for his 40th birthday. I am super cheap, so the thought of spending this much on binoculars was hard to come to terms with. But my husband is an avid bird nerd, we live in an area that sees a fair amount of birds and wildlife and he only turns 40 once! My father-in-law is an ornithologist and knows a lot about high quality binoculars. I asked him to give his opinion on this gift before I purchased them. He said that the price was very reasonable and the quality is exceptional. I didn’t buy the extra warranty because he told me that the company was extremely reliable about covering their products. My husband is very happy with them and loves any opportunity to take them out. They are very crisp and clear to look through. I’m not finicky, but I will trust the opinion of those that are and say that these are very good quality. The price is still painful to me, but I’m told that you get what you pay for and these are worth it.

These things are awesome. I have put them beside some swarovski and the imagine is almost identical. Low light situations would be the only area these do not do as good as binos that are way more expensive. Getting these dialed to your vision is very easy. I’m kind of biased to leupold for the quality to value but I was super impressed with these when I received them.

These Binoculars are Crystal clear. I was having trouble finding binoculars that had a narrow interpupillary distance. These will fit people with a smaller face and eyes that are closer together. I had purchased the Vortex 10x50 the Diamond back 12x50 ( these vortex models were too big for my face, casting black shadows) and the Nikon Monarch M7 10x42 (Nikon will fit someone with a smaller face). The Leupold BX 4 10x50 blew them all out of the water. The Clarity can’t be beat. They were Clearer and brighter and actually felt lighter. I hope this helps some people. Because It took me some research to get the right ones. These are most definitely the best!

Went with these on 10/29/23. Fast shipment!!! They arrived and they are pretty nice. Wide field of vision edge to edge, nice focus setup. Everything feels tight and smooth. Very light with amazing light gathering capability. WAY Better than my Diamondbacks, but not even close to my Kiabab's. They seem as nice as my Steiner HD 10X42's (which the BX-4's are replacing since my Steiners broke). I like this double bridge design, hopefully they will hold up. At this point; feel good about this purchase.

This is great glass. I bought these to upgrade from a set from another brand that I have had for 10 years. They are incrementally better than my existing set, but I was surprised that they were not significantly superior at twice the price. I am a big luepold fan, and this is the first time I have made a purchase that fell short of expectations. The pair I have now are no longer in production, the brand is out of business. Again, these are great but now $600 great.

Won't find a better pair of binoculars, easy to adjust for your vison, high quality construction and compact enough for carry. Of course they are expensive but when you use them you won't want anything else, crystal clear and ultra sharp. I use the staoptics tripod mount which is great for stability (put a lock washer between the mount screw and the binoc mount for a tight fit). The BAK-4 class are important numbers to remember when looking for good binocs. They are a little heavy but the trade off is excellent clarity. I "Star Gaze" a lot and these are fantastic much clearer than cheaper models. I was able to clearly see five of Jupitors seventy moons but not with my other cheaper 10x50's.

May seem expensive but definitely worth it. Its my travel bino because it doesn't take up much space.
