There are always more kinds of binoculars than there are birders.
The really special thing about birders (bird-watchers) is they almost always have more than one pair of binoculars.
And often they have many types of binoculars as well as a spotting scope or camera or two. It is the active birders who are perhaps the best people to review and comment on binoculars. True, the companies have valuable input, but it is the everyday application of these types of binoculars that proves the claims.
This is the first in a series of posts on binoculars by specific companies. Nikon is well known for its cameras and binoculars. Therefore, I start here with comments on Nikon binoculars. In this series I plan to include costs, a place to purchase them and customer reviews when they are available.
