The 4x10D CF binoculars have a thickness of just 19mm and a weight of only 65g—making them the thinnest and lightest, ultra-compact binoculars that Nikon has ever released. Ideal for indoor environments like galleries, museums, and theaters, the binoculars provide a 4x magnification with 1.2m close focus distance for bright and clear views. The multilayer-coated lenses and prisms enhance light transmission, ensuring crisp images. Their simple design—free from dioptre adjustments—makes them easy to use, with just a quick focusing adjustment.
