Pentax UP 10x25 BinocularsThe Pentax UP 10x25 is a compact reverse porro binocular with a unibody design that locks the objective lenses into the body with the eyepieces on a dual axis mechanism that helps you keep a perfectly symmetrical interpupillary distance when adjusting. The 25mm lenses are fully multi coated to reduce glare while maximizing light transmission for a brighter image. Also with the 6. 2' close focus these are great binoculars for near and far observation!
