The Vixen Foresta Waterproof & Fogproof Roof Prism Binocular is available in either 32mm or 42mm objective lens sizes, with either 10x or 8x magnification.  While the 32mm versions do not have the viewing angle of other premium binoculars, they are also much lighter than their competitors...sometimes by up to 20% or more!  Eyecups are the popup type for speedy, simple exchange-these are binoculars that can be quickly shared between those with and without glasses.  Styling is unconventional, with the rare focusing dial location towards the objective lenses.
