These Nikon 7x50 Action Binoculars feature several layers of antireflective coating along with traditional Porro-style prisms, delivering clear and high-contrast images. Porro prisms are not merely a throwback to the past; many users of optical devices believe they provide a superior sense of '3D' depth perception compared to the slimmer and more prevalent roof prisms. The large 50mm objective lenses possess excellent light-gathering capabilities, ensuring bright and clear views even in difficult conditions such as dawn or dusk, or when looking into thick underbrush. The turn-and-slide eyecups, combined with comfortable eye relief, facilitate easy viewing without causing eye strain, particularly during extended observation periods. Optical Performance Traditional Porro prism light path produces a rich depth of field, allowing the user to discern the relative distances between objects in the view Anti-reflection multicoated optics produce neutral and accurate color fidelity and improve contrast and image brightness 42.7° apparent angle of view reduces the appearance of visible hand shake, which is especially common with higher-power optics Use and Handling Large slip-resistant center focus wheel is easy to manipulate, even while wearing gloves Right-eye dioptric correction compensates for individual user's optical prescription for clearer and sharper views Turn-and-slide eyecups for comfortable use with or without eyewear
