BOSMA8x42 HD Binoculars: Silver-Plated BAK4 Prisms, FMC Broadband Coating, Comprehensive Optical Glass, Nitrogen-Filled, Waterproof, Fog-Proof, Durable Rubber Armor

These binoculars have a very good focus and the zoom feature works flawlessly. They feel slightly heavy but that is not an issue and is to be expected with glasses of this quality.

Surprisingly, good quality easy to operate very good field of view. Good clarity.

I have a friend in the United States, he very much like me to send this binoculars, he and I are both outdoor enthusiasts, quite a study of binoculars, when I traveled in China when I heard of this brand, I tried to buy their Golden Tiger Ⅱ (that is, this binoculars), his optics are good enough, sharpness and image clarity is good enough, he is also very easy to focus, it is no inferior to vortex, Celestron, in China BOSMA even more popular than them all, compared to similar products to be much cheaper, so I chose this binoculars for my friend, my friend got his hands on it can't wait to ask me again to go on a trip together, he said this binoculars are perfect enough, he loves it, for which I am very happy!!!!

These have too much field curvature the build quality of the unit is actually very good . Maybe I'm just old but my eyes did not work well with these binoculars nor did my brides. I have a pair of KOWA 6x30 ranger binoculars well I had a pair my wife decided they fit her eyes better so I would say pass on these. Unless you just need some tiny binoculars I was more disappointed in the optical quality versus the KOWA. If you're reading this trying to decide if you want to spend the money my astronomy teaching recommendation is to skip and get the ranger binoculars 6x30 you'll be much happier you might have to buy two pair

Very solid, well-built with noticeable weight that suggests a lot of internals. Due to the weight factor, I would not consider this for hard-core bird viewing. Sharpness of image is there but edge-to-edge sharpness to the edge of the field-of-view is not as sharp. Maybe an Ed lens and/or flattening lens would be needed to achieve that. So, why did I purchase this binocular. First, I don't see silver plating on binoculars very often, which is used to increase light transmission. I want to be able to see in low-light conditions. Second, broadband coating helps with color reproduction. Third, the waterproof rating is better than others, in that, many only have 20 minutes of underwater exposure rating while this one is 30 minutes. It's also fog proof. And finally, the appearance. A little gold breaks up the monotonous black seen in most binoculars. In short, this is a good pair of binoculars for the cost. The warranty is lifetime and transferrable. I compared this binocular with my Leopold binocular (Yosemite line) and it is just as sharp. If you are looking for edge-to-edge sharpness 'throughout' the 'whole' viewing field, including the circumference 'edge', then I would suggest considering a more expensive binocular with ED lens such as this one from Bosma: https://www.amazon.com/BOSMA-Binoculars-10%C3%9742-Wide-Angle-Flat-Field/dp/B0D2D27M76/ref=sr_1_20?crid=2C4ZFZQ01M5BS&dib=eyJ2IjoiMSJ9.CrrVP2rC9KtBZX_H0JG2TDrj65oZZ2CuJyJ4_2SRVrLGjHj071QN20LucGBJIEps.TuPjOmJuBiaejpBQR4BFkzdpxmZzUvCOhR_KkDuTWi0&dib_tag=se&keywords=apo%2Bbinoculars&qid=1719171356&sprefix=apo%2Bbin%2Caps%2C1470&sr=8-20&th=1. For the price and free returns, you can't go wrong giving this binocular a try.

Price was right and I am amazed at the quality. Lightweight. Smooth operation

The size is small and the weight is also very light, which is suitable for long-term put in a backpack or car. Because it is clear enough, I would be very willing to let my kids or myself to use it.

This binocular set comes with lens caps, a carrying strap, and a carrying case, and of course the binoculars. All visible components appear to be well made from materials of at least good quality.There are 2 pair of lens caps, 1 for each of the 2 pair of viewing lenses, and both made from some type of rubber or silicone material. These caps are completely removeable, so take care not to lose them.There is a reasonably long neck or shoulder strap, which is attachable, or detatchable, to and from the binoculars. The material is like a type of canvas or belt material, and is quite thin, somewhat like a lanyard. While it does not appear to have super strength, due to it's thinness, it certainly does appear to be plenty strong enough for the general task of carrying a set of binoculars around.The carrying case is also made of a kind of canvas, which is reasonably thick, and tends to hold it's general shape with relative ease whenever empty. The case is just the right size to comfortably fit the binoculars into, with the lens caps and carry strap attached. The case is closed by a flap of canvas that wraps over the opening, and is secured into position by a velcro strip.The binoculars are of a common size for such an item, although they do feel a bit heavy-weighted for that size. The width distance between the lenses can be easily adjusted by hand, as can the lens viewing range, by means of a turn-dial.It was almost dusk when I tested these out, and the sunlight was rapidly fading. Despite this, I was still able to see several wild deer grazing in the distance of the open field across the street from my home. Upon lowering the binoculars, I realized the same deer were no longer visible to my eye. And so I went back and forth like this a few times to be certain. And so I can confirm that these binoculars are able to see and magnify these deer up to a recognizeable size, even at a great distance.The overall functionality and performance of these binoculars is impressive, in my opinion. While I may not be a top tier hunter or an optics expert, I am an average user. 5 out of 5 stars.
