Worth the money

    • Very good image. A significant upgrade over my 10x50.
Size: full-size
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. ... show more

    • OK for price.
Size: full-size
I have an early 1960s pair of Tasco 7x50 binoculars that my mom bought for me when I was a kid. They are unbelievably clear and sharp. I purchased the Nikon 16x50 to bring things a little closer. The Nikon’s are OK but not as sharp. I use them for looking at the beach from my condo. If I didn’t have my old binoculars to compare to I would rate higher but since I know what real clarity looks like. I rate them 4. As others have mentioned the eye cups are too big. They hit the nose to far from the eye. The other issue is that 16x50 binoculars are hard to hold steady. This is not the fault of the binoculars, it has more to do with the large magnification. Keeping in mind they are selling for $120 I think they are worth the money. I suggest a 10x50 might work better for most users. ... show more

    • Great Bang for the Buck!

Wow! Impressive image providing a sharp and bright edge to edge full view experience. First binoculars I have owned that actually seem to correct for my astigmatism allowing me to focus and see clearly without having to wear my glasses ... Thank you Nikon. Just how impressed were we with the quality versus cost of these binoculars, enough to purchase a second pair so that both spouses will have a pair of their own instead of sharing and one missing part of the action along the coast. 16x requires user to remain steady but it is worth it. Comes with adapter for tripod use if needed. UPDATE 03/14 ... There have been so many positive comments about these from visitors that we have since bought a third pair for our visitors to use. ... show more

    • Great for distant viewing

I'll admit, I do not know a lot about binoculars, lenses and the like. I wanted a good pair of binocs for use at the lake house to watch birds/deer/beavers as well as to watch people (because when you're on a lake, you want to see what everyone is doing). These binocs are not for sitting on a deck looking at objects within 25-30 feet. You'll want to use them for looking at objects 100 yds or 1/4 mile away. They are a little heavier and that's fine. I use my knees or railing for balance. The package comes with a tripod adapter (if you have a tripod, I don't). Overall great value, I might purchase a pair for my father for father's day. ... show more

I've had a set of Nikon 10 x 25 since the mid-70's (in the pic), and finally broke down and bought a more powerful set. I also bought the tripod adapter that was offered with it, however it DOES come with an included adapter if you don't want to spend another $10 on the one offered, although the adapter offered is a little taller and nicer. I am very pleased with the view through the 16 x 50! On a tripod I can even make out the moons around Jupiter. Because of the higher magnification shakiness is very noticeable, but if you cup the binoculars with your fingers and stick your thumbs back and rest them on your cheeks it really helps to control the shakes. Pleased with them so far. Addendum: Others have commented on the lousy lens caps, I have to agree, they are not solidly mounted enough in place, too easy to loose them. ... show more

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. ... show more
