Swarovski's 10x42 EL Binoculars feature a high-transmission optical path, legendary Swarovski optical coatings, and a weather-sealed magnesium-alloy housing that delivers an exceptional performance with the ability to withstand extreme conditions, and were developed to give hunters and birders a slightly higher magnification than standard 10x optics while preserving a wide-angle field of view, long eye relief, and limiting visible hand-shake common in higher power glasses. The large field of view and optics providing edge-to-edge sharpness make the EL 10x42 binoculars versatile to use. The 4.2-mm exit pupils also produce bright images in poor light conditions. | Swarovski 10x42 EL Binoculars with 2021 FieldPro Package in Green.
