    These binoculars have a clear field of vison, are fairly light weight and easy to focus. The only improvement I would make is a better way to attach the large lens caps. The eye piece lens cap attach securely to the strap. Not so with the others. I made a few modifications and now the large lens caps won’t get lost. I like these binoculars and would recommend them.

    Good binoculars. Price is good. Vision image is good.Disappointed they are made in China since NIKON has been an iconic name brand of Japan!!I have a 35mm Nikon camera circa 1968 and it is still an excellent camera!!! Hope these binoculars are just as good???

    These were great for our Alaskan vacation. My only criticism is that the caps aren’t connected to the binoculars or to each other and can easily be lost. They worked well for the adults and children.

    I’ve always loved Nicon optics and own several. This one is by far the best. Sharp, clear picture, lightweight and very easy to use. Thanks for letting me tell you how happy I am with this purchase.

    As I’m new to birdwatching, I looked on the Audubon Society website to see which bins were recommended for beginners. The Nikons were at the top of the list in the low cost ratings. Light, compact and easy to use with surprising optical clarity. Would highly recommend them.

    I bought these as a gift for my husband. I am sure he will really like them. They are a much better quality than the old pair we have.

    I actually bought these for a friend – she said “these binoculars are far superior to any she has used, they are light weight and excellent viewing”.
