Oberwerk high-quality 60mm binoculars- at a 50mm price! That extra 10mm doesn't sound like very much- but 60mm objectives gather 30% more light than 50mm models (surface area = pi*r2). With that much extra light-gathering power, these are ideal for a low-cost entry into binocular astronomy. They are also excellent for birding, nautical applications, and surveillance.
Not only do you get big 60mm objectives- you get the same highest-quality BAK4 prisms that are found in much more expensive models. All air-to-glass surfaces are fully coated to decrease light loss due to scattering and reflections. Objectives have highest-quality green/purple broadband multi-coatings, typically only found on binoculars with much higher price tags.
All Oberwerk binoculars have rugged rubber-armored metal bodies, all-glass lenses, right ocular diopter adjustment, brass 1/4-20 tripod adapter threading, case, caps, and strap.
