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.

To read Ben’s article, and the entire issue of Birder’s Guide to Gear online (and for free!), just click here. Please share any comments or questions you have for Ben in the comment section below.
