The green and black 8x42 Crossfire Roof Prism Binocular from Vortex combines fully multi-coated optics, which deliver bright and clear images, with a durable and comfortable-to-hold body. With an 8x magnification and 42mm objectives, you obtain an optimal tradeoff between notable magnification, lower image jitter due to unsteady hands, and light-gathering capacity that delivers bright images. You can easily spot your targets with a wide 7.5° angular field of view and an enhanced depth of field and quickly bring them into focus with a center wheel. In addition to observing distant scenes, birds, and game, the minimum focus of 7.5' allows you to study in detail close targets like animal footprints, marks, or landscape features without moving away from your subject. The binocular also features a 5.3mm exit pupil, a 17mm eye relief, and a 56-76mm interpupillary adjustment range.
