Would you recommend them on a boat. Sailboat. Do they fog up? How are they with objects at 1 mile? Apr 15, 2014
I'm a sailor as well. I haven't taken these on a boat, but I've used my older Nikons (1970's) on a boat for years with no problem. That said, if I were paranoid about it and could afford it, I'd buy a waterproof pair.
Oh yes. 7 X 50 size binoculars give the highest resolution and magnification available in a hand-held unit with no external support device needed. I use mine for bird watching all the time, and the optics are excellent with Nikon.
What is the close focus on these binoculars? Oct 16, 2014
The following link will list the Nikon factory specs: http://www.nikon.com/products/sportoptics/lineup/binoculars/aculon/aculon_a211/spec.htm It shows 8 meters (approximately 26 feet) for the 7 x 50 Aculon. If I am looking at something closer, I am probably using a camera with a telephoto lens. Seven power is about as strong as most people can hand hold steadily without a tripod. The 50 mm lens gives more light gathering power than your eyes which makes these binoculars great for dusk and night viewing.
From the shape, they are porro prism. Binoculars with a roof prism have the eye pieces in line with the lens barrel: there in no "jog" in the light path
I am not sure of the wight, but they do not seem overly heavy or bulky. The strap is adjustable which is nice since my husband and I are not the same height. We take these backpacking to watch the stars or spot wildlife so they are not a burden on long treks. It s very easy to refocus quickly and with one hand if needed. We are very happy with these.
Where is it manufactured? Apr 17, 2015
Nikon is a famous Japanese brand, so I would expect it to be made in Japan. I bought my Nikon 35 mm camera in 1970 when I went to Japan for studies and got the camera for one quarter the price I would have paid in America. There are no marks on the binoculars to indicate its origin apart from the Nikon name. I have found these binoculars to be excellent for my bird watching. A few months ago I met some other people who had also bought the same binoculars.
