Our SB50 binocular features individual focusing optical system, which allows for close-up focusing and more precise adjustments on any viewing distance. LN-SB50 feels just like a daylight binocular with such features like inter-pupillary adjustment and individual focusing eyepieces. Unit features low-battery indicator and a built-in tripod mount allowing for extended observations, which is great for nighttime nature viewing and law enforcement. This is also one of the very few night vision binoculars that can be adapted to the SLR cameras with the help of our LN-CAS camera adapter system.
