Leica Duovid 8 + 12 x 42 are the first premium binocular to feature such switchable magnifications. This is a superb master of the various tasks of travel placed upon a binocular, giving either steady images and tons of light or awesome pulling power as needed. The optional tripod adapter is recommended for use with the 12x magnification and extended observation periods.
