Pros: Thick solid metal tripod adapter. 18mm wide eyepiece, vs 16mm on my Celestron 10x50 and 13mm on my Tasco 7x35 1.5 inch wide neck strap with leather backing Thick, padded carrying pouch, without a strap My reflection in the Nikon lenses (Objective and eyepiece) are dimmer than in my Celestron 10x50's by at least half, which is good for the Nikons. Sharp images with easy smooth focus. Not much turning required to focus. Near focus of 15 feet not 28 listed, but I am a bit near sighted but don't use glasses Light and easily hand holdable by me, but I've had lots of practice and am young. I can hold it steady with one hand. Measured exit pupil at thinnest point, and it is exactly 3.1mm, vs 4.3mm on Celestron 10x50 Pressing my eye sockets against the eyepieces does not move the focus I can see veins in distant tree leaves that my 10x50 only shows the general leaf shape of The objective covers stay on easily and can clip onto the neck strap. As I look around my dark house inside, lit only by one computer screen, the view through the Nikons is no darker than with eyes. The smooth sides of the eye cups makes it easy to tape paper light shields on them to block side glare. It made the viewing that much more enjoyable. Careful measurement confirmed that the apparent field of view is indeed 61 degrees, a degree wider than my 10x50 wide angle, and that the magnification is indeed about 16x. Cons: During the day, I must look straight forward. I can't move my eye to look around the field of view like I can with my 10x50, because the exit pupil is smaller and gets blacked out. This is not a problem at night. At 5pm, with my pupil a bit larger, this is no longer an issue. I get better use during the day if I'm very careful to measure my interpupilary distance and match the eyepiece distance to it exactly. The eyepiece covers are too big and fall off the eyepieces. But they do clip on the neck strap so they don't have to fall on the ground. With some tape, I can make my own covers that double as side light shields. The carry pouch, although nicely padded, is small, and you have to really stuff the binoculars in there to barely close it. === The Andromeda galaxy and M33 are easier to see with the 16x50 than with 10x50. I did not see a dimmer view with the smaller exit pupil. In fact, the Nikons seem a bit brighter, even when looking at houses without any porch lights nearby. The Pleiades look better and show more stars in the 16x50. When looking at Venus, near sunset, I noticed some faint stars with the 16x50 that I could not see with the 10x50. Orion's belt also had a denser star field in the 16x50 than in my Celestron 10x50, though not by a large amount. Venus looked larger, but I still could not see its phase. Jupiter looked larger and rounder in the 16x50, and the moons were a bit easier to see but still small. I could not see stripes on Jupiter. The moon looked a bit better too, though not spectacular. I did not see any extra details at 16x that I could not see at 10x; however, I did not have to look as hard to see them. Any detail obvious at 16x could be verified at 10x. I was getting tired from being up late, and shake was more noticeable in the 16x than the 10x. I can locate M82 and M81 in my 16x50, but not in my 10x50. M51 and M101 are much easier to locate too. During the day time, the 16x50 expands every detail I could be curious about with my naked eyes. It makes me feel like I'm over on that distance hill, walking through that tall grass. The 10x50 is more for seeing the full picture. 16x is as high as I can go and still have good depth of focus on terrestrial objects at different distances. At 25x, I have to refocus for each distance. Also, 16x is as large as I can go and still figure out where I am in the sky just by panning around. At 25x, I can just point and look but not know where I'm truly at unless I recognize and object of known location. I recommend owning a Nikon 7x35 and a Nikon 16x50 for both big picture views and detailed inspection. Get a telescope if you want more power.

Can you get a pair of 16x50 binocs for $40? Yep. Then why pay $140? Because the quality is worth it. I have bought dozens of Nikon products over the last 30+ years and have never, not once, been less than thrilled with the quality and dependability of their products. You simply don't have to question whether it is going to be good or not. These binocs are no exception. The only criticism I have is that the diopter adjustment knob is a little hard to use if the eye cup is down all the way and you have large fingers. Apart from that these are great! The case is nicer than I would have expected too, very well padded. The Nikon tripod adapter is not plastic but solid thick aluminum. Even the neck strap isn't El Cheapo. So yeah, if you are looking to spy on the neighbors, go spend $40. But if you are looking for a high quality pair of binocs, you can feel very confident about spending the extra money for these. You really do get what you pay for...and that is a good thing. ****EDITED OCT. 29, 2017**** I do have one beef with Nikon that needs to be mentioned here. I buy a lot of their products because they are simply that good. But when you pay top dollar for something you expect that the details will reflect that. And on the binoculars (and other Nikon products) they do...except the lens caps. Nikon makes the worst lens caps on the market, whether it is cameras, or binoculars, and these may be the most frustrating lens caps of all time. The eyepiece cap just sits loose over the eyepieces. There is not even tension to hold it in place. The barrel end caps don't go over the barrel like most caps do, they snap into the inside of the rim...if you set them in just right. If you don't, then they stick in place for a few minutes and then fall off. Nikon has fixed something that wasn't broken here, and ended up making it worse. Fortunately, after-market standard lens caps can be purchased cheaply, and I would highly recommend it. Again, not an issue with the binocs themselves, but just a fairly important detail that could have been done better. -1 star.

Haven’t tried the tripod adapter, but looks solid. When propped I could see 4 moons of Jupiter! I could also read the “John Deere 318” off my neighbor’s mower at over 1200 ft, that is almost 1/4 mile! (Not a pic through the lens, just a stock image) Detail of the moon is spectacular. Measurements/ Dimensions provided in the pictures. Yes, the image is shaky if you aren’t very steady, but at 16x that should be expected. Focus is sharp and smooth. Weight is not bad at all. You don’t pick them up and notice anything different from any other pair by weight. The grip and feel is great. Able to focus closer than expected. Cons: diopter adjustment is crazy tight. Lens caps are terrible. Especially the eye piece cover. Easily falls off. Will either need an elastic band to hold it, or replacement covers.

Was between this and their 10-22x50 zoom model, am very satisfied I chose this pair. The 16x zoom provides plenty enough viewing power as I can now see actual people in their boats out on my favorite lake and tell who's catching fish and methods they're using. Can also see all the wild life close up now, not to mention a decent view of the moon on those clear evenings. With 16x all you need to do is select your target and focus, no messing around with the zoom which I suspect I'd be doing if I purchased the 10-22 model, not to mention the cost savings. I actually bought a used tripod for it and it connects easily with the included adapter, but in hindsight probably overkill as I ditched it on my last few trips because I can easily hold it steady enough for my needs.

They are just that good. I have owned them for years and compared them to many pairs. Sharp on the axis and across the field. Some give a low rating and say that the image shakes too much when holding them. This is not the fault of the binoculars but the 16x they create. Don't blame the binos for doing what they are designed to do. Shaking is a result the the extra magnification or the user's inability to hold them steady. Yes they are heavy but that is called "Quality build" - Harry

In one word...WOW. I have a pair of 20x80 giant binocs, but these are way better. Very light and easy to turn focus. If you get above 16x power, binocs are very hard to hold steady. These are perfect, though you will still have to have a steady hand, but it's worth it for the close views. Great rubber gripping, strap, everything. Can't say enough good about these. Though they have an exit pupil of 3.1, they are still terrific...as they give you a nice wide field of view and super sharp. Plus they are Nikons, which means very good optics. Taking these to Yellowstone in a couple of months and they'll be constantly hanging around my neck.
