The new Oberwerk 20x90mm is an exceptional value. Huge 90mm objectives for a price that is less than many competitve 80mm models. Features full broadband multi-coating (all air-to-glass surfaces, including prisms), all-metal contruction with rubber armor, braced and hinged objective tubes, and a built-in mount - all at a shockingly-low price.
This binocular features a wide-angle 3.2° field of view, with very good sharpness across the entire field. The eyepieces have fold-down eyecups that work well with glasses (eye relief is a comfortable 17mm). Easy-to-operate center-focusing. Includes objective covers, ocular caps, and a custom aluminum-framed hard case.
