When you make a couple of crucial choices regarding the construction of the binoculars at a certain cost level, you get exceptionally good image quality in this price range: these binoculars are not waterproof, and they use a so-called Porro prism structure, i.e. it is a traditional "angle model". As money has been saved in these areas, the quality of the optics has been given a nice boost. The Scenery 8x40 also works in slightly darker conditions. The reversible eyecups allow for use with glasses. The unusually large apparent field of view in this price range also helps here. The Scenery 8 x 40 is a solid choice for birding and other outdoor activities. - 8x magnification - 40 mm objective lens size collects light well - Wide field of view: - 130 meters to 1000 m, 7.5°, apparent field of view as high as 64° - Pupil size as high as 5 mm - Glass type: BaK-4 - Diopter adjustment +/-4 - Eye relief 20 mm - Pupillary distance 54 - 74 mm - FMC coating - Twilight number 18 - 10 year warrant
