Your turn: Binocular 101

Screen Shot 2013-12-27 at 4.31.40 PMHaving a basic understanding of how binoculars work is a plus for anyone considering investing a few hundred dollars in a new one. Just what is “exit pupil”, and why should that concern you if you wear glasses? Does a bigger number in front of the X mean that the image is brighter? In this issue of Birder’s Guide to Gear, Ben Lizdas breaks down the basics for us in “Binocular 101” by defining the parts of a binocular (at right) and then explaining how they work together to gather light, and then transmit it to your eyes.
