National Geographic 10X50 Porro Binocular
Fifty millimetre objectives are what make the National Geographic 10X50 a low light instrument. The wider the front lens, the more light reaches your eye, and that is what decides whether an animal at dusk resolves into something identifiable or stays a shape. It is also why this pair is recommended for stargazing as much as for daylight use.
What the 10X50 gives and what it costs
Ten times magnification pulls detail in noticeably closer than the more common 8x, which suits bird watching and wildlife monitoring at range. The trade is that it also magnifies hand shake, so bracing against a fence post, a vehicle roof or a tripod makes a visible difference at this power.
Protection
The body carries water resistant, rubber coated armour that absorbs small bumps and handles brief exposure to water. An included neck strap keeps them secure and, more usefully, keeps them hanging ready rather than packed away when something appears.
