HD Professional Black 10x42 Compact Folding Roof Prism Binoculars For Adults
Roof prism binoculars appeared simpler than Porro prism binoculars. But inside, they had a more complex light path and required much greater optical precision in manufacturing.
So roof prism binoculars have two straight tubes, making them smaller and more compact.
These binoculars feature BK7 roof prisms with 10x magnification power with a 42mm objective, giving great viewing with minimal shaking.
