It’s a full-sized binocular – not for small hands and weak arms. But if you like such dimension and weight, you will be impressed of the image you get through this roof-prism binocular. Pentax had made a good job of it: The Super Multi-layer Coatings and the Phase-coated prisms give a really bright, very sharp and absolutely clear image. Ok, the “big-three-brands” will perform a little bit better (especially they have larger fields of view), but think of the price you have to pay therefore! I’m lucky with my choice!
