Nikon is obviously famous for its cameras, but it also invests some of its optical expertise into binoculars ... is also now making its VB50 and VB99 mini V-mount batteries available in green ...

They're in entirely different price brackets, but is there really a major difference between the Olympus 10x25 WP II and Nikon Monarch 5 20x56 binoculars when it comes to nature-spotting?
