The Nikon Fieldscope ED50 angled in green is a compact spotting scope designed for outdoor observation with its 50 mm objective lens diameter. This angled model features ED (Extra-low Dispersion) glass in the objective lens system, which reduces chromatic aberration and provides clear, high-contrast viewing with accurate color reproduction. The optical construction delivers bright images suitable for various lighting conditions encountered in field use. With dimensions optimized for portability, this scope measures approximately 28 cm in length and weighs around 450 g, making it easy to transport during extended outdoor activities. The waterproof housing is filled with nitrogen gas to prevent internal fogging when exposed to humidity or sudden temperature changes from -10 °C to 50 °C. The green exterior finish provides camouflage benefits for wildlife observation while offering durability against environmental elements. The angled eyepiece design allows comfortable viewing from various positions, particularly useful for extended observation sessions or when sharing the scope among multiple users. This model accepts interchangeable eyepieces (sold separately) to customize magnification levels according to specific observation needs. The focus mechanism provides smooth adjustment for precise image clarity across different distances. Constructed with magnesium alloy components, the Fieldscope ED50 maintains structural integrity while minimizing overall weight. The rubber armoring offers a secure grip and additional protection against minor impacts during field use. This spotting scope is suitable for birdwatching, nature observation, and other outdoor activities where compact, high-performance optics are required. The successor model to previous Nikon compact scopes maintains the brand's optical standards in a more portable format. Accessory compatibility includes standard Nikon spotting scope eyepieces and various mounting options for tripod use.
