What customers say about "Key Specs"
Nikon Prostaff 5 (7571) 10X42 Binocular (Black) by Nikon
  • I would highly recommend these to anyone looking for a good set of optics!
  • Clear, durable, and great Bin for hunting
  • Works well with eyeglasses. Very nice quality, very happy.
  • Sent to Nikon for warranty repair, because eye relief issues.
Nikon Prostaff 7 (7538) 10x42 Binocular (Black)
  • Depth perception and color accuracy are superb, tending towards a slight excess of 3D effect.
  • Great binoculars, solid feel and excellent depth of image.
  • Light weight, focus fast and clearly and have a bright field of view.
  • The eye relief is a little less than perfect in terms of setting the cups for those of us who do not wear glasses and the lens covers are a bit of a pain in the rear.
  • The lens caps are a joke. You can attach them to the cord but that doesn't work all that well.
  • My only problem is that the lens caps are terrible, especially the little ones.

What customers say about "Features"
Nikon Prostaff 5 (7571) 10X42 Binocular (Black) by Nikon
  • Manufacturer tells the truth, really waterproof.
  • Fully Multicoated lenses ensures to see a rich colors, like it
  • The multi-click turn-and-slide rubber eyecups make it easy to find the correct eye positioning to see the full field of view. Very comfortable to use, good purchase.
  • I went out with binoculars into the fog and saw nothing. Fogproof??
Nikon Prostaff 7 (7538) 10x42 Binocular (Black)
  • Binoculars is extremely clear, easy to focus and have a great rubberized coating on the outside.
  • Quite light for a large binocular and very good quality for a set that was not expensive.
  • Great binoculars. I bought them for my dad to replace his Bushnell binos and this is head and shoulders better in quality and clarity. Great light gathering. Good eye relief.
  • As other buyers, I don’t agree with the protective caps. Those at the eye side are BIGGER than the rings, and those at the front side don’t have a good hole to hold in the neck strap.
  • The only problem i have found is that the eye cup covers fall off some.
