Zeiss Terra ED 10x32 Binoculars - GrayZeiss Terra ED 10x32 Binoculars have new cosmetics. This is the original gray and Black is the new color for the 32mm models. Also new is a pebbly texture on the rubber armoring grip. A cordura case is now standard. The optics and the rest of the accessories remain the same: fully multi coated ED glass, phase corrected BaK 4 prisms, 405' FOV at 1000 yds, and a 4. 9' close focus. And, of course, the Terras are waterproof and nitrogen purged.
