About the Bushnell 7-21x40 Porro Prism

A variety of styles and features appeal to a wide range of users from students of nature to concertgoers. Outstanding light transmission through fully-coated optics ensures bright, crisp clear viewing. Standard-size models feature InstaFocus for fast and easy focus on a moving target.
