Its optical system provides a wide 4.2° field of view at 9x and can focus on subjects as close as 9.8 feet (3 m). With fully multi-coated optics, phase-coated BaK4 prisms, and 15mm of eye relief, this scope is engineered for hikers, birders, and travelers who refuse to compromise on optical power for the sake of portability.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA \"Micro\" Spotting Scope Weighing Just 590g\u003c\/h3\u003e\n\u003cp\u003eTraditional spotting scopes are often too large and heavy for extended hikes or travel. The Hummingbird shatters this limitation with a compact design measuring just 208mm long and weighing only 590g, making it small enough to fit in a large pocket or pack without penalty. This \"micro\" form factor allows you to bring the power of a spotting scope to locations where you would have previously settled for less.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e9-27x Zoom with a 56mm Phase-Coated BaK4 System\u003c\/h3\u003e\n\u003cp\u003eDespite its small size, the Hummingbird's optical system is built for clarity and detail. The 56mm objective lens gathers ample light, while the fully multi-coated optics maximize transmission for bright, high-contrast images.
