Nikon is pleased to announce two exciting new Fieldscope models - the ED50 and ED50 A. Remarkably compact and lightweight, these Fieldscopes also provide superior waterproof reliability (tested to a depth of 1m for 5 minutes). These Fieldscopes deliver outstanding value for first-time users and serve as a reliable backup for veterans. They are fully compatible with nine conventional Nikon Fieldscope eyepieces. Both models have been designed primarily for birdwatching and digiscoping applications.
