The Aculon A30 10×25 Binocular from Nikon is designed for mid-range observations, with an anti-reflection multi-coated lens system and roof prism optical path that are designed to work together and transmit clear images with enhanced contrast and accurate color representation. Nikon built the A30 with their ecologically friendly Eco-Glass, which is manufactured without lead or arsenic to be better for the environment. This version of the Aculon is ideal for sporting events, general nature observation, and sightseeing around town or around the world.
