These binoculars are 4 x 36 with a straight through, non-prismatic design from Russia, called a Galilean binocular. This design is brighter than binoculars using prisms. They are currently sold by Kalinka Optics where they are called listed under BGF-2, or at Russianoptics, item# RO30. The optics are very bright and very nice.
However, they have low eye relief so I can't use my eyeglasses with them. There is no right diopter so I can't focus my eyes separately, which I need to do. So, if either of those issues affects you, these are not for you.
These are barely used and come with a zippered soft leather case (pouch, really). Hoping to get $27.50 plus $5 shipping.
