Swift 9x63mm ZCF Ultralite Binoculars - 764 are classicly designed porro prism binoculars. The Swift 9x63 Ultra Lite is, as the name would imply, quite lightweight for its objective lens diameter of a huge 63mm. You'll be able to easily observe your subjects in all lighting, with particulary remarkable resolution apparent during twilight. This makes a great binocular for astronomy observations, and provides an ample 22mm of eye relief for those who wear thick eyeglasses.
