Hawke Panorama ED 8.5x42 Waterproof Binoculars feature the latest Flat Field technology, ensuring the image has minimal field of view curvature right to the edge of the field. The result is a sharp and true image, one of the best in the market place. Hawke Panorama ED 8.5x42mm Binoculars also have some key features offering excellent benefits to the user. The ED glass eliminates Chromatic Aberration, while the Dielectric coating on the prisms in conjunction with the fully multi coated lenses provides the brightest image available in a Hawke binocular. Along with the stunning optics, the exterior design and function have not been over looked. The locking dioptre setting is safely positioned underneath the quick ratio (1. 7 turn) focus knob. The rubbers have been designed to allow for comfort yet provide adequate grip. The Hawke Panorama ED 8.5x42 Binoculars is topped off with multi-stage twist-up eye cups, stay-on lens covers, and is also supplied with a comfort neck strap and genuine leather case. Once you have looked through a Hawke Panorama ED, the difference is clear.
