Focus OpticsFocus Optics Focus Observer 10x42 HD Green

Focus Observer 10x42 HD from Focus Optics is a pair of binoculars for hunting, hiking and birdwatching when you want to get really close to the subject. The higher ten-times magnification provides clear detail at longer distances, while the bright 42 mm objective lens still allows observation in low light.

Sharpness, magnification and active observation
The advanced optics with phase-corrected BaK-4 prisms provide a clear, high-contrast image where details stand out clearly, even when the light is weaker at dawn or dusk. The ten-times magnification makes it easier to distinguish small details, while giving you a somewhat narrower field of view compared with lower magnification. The open design, twist-up eyecups and generous eye relief provide comfortable use both with and without glasses.

Durable construction with effective FMC coating
Focus Observer 10x42 HD is built to handle many trips out in the field, with a durable rubber armoring that provides both grip and protection against impacts. The binoculars are waterproof and fogproof, so you can use them in rain, fog and humid environments without worrying about the internal optics. Full multi-coating (FMC) on the lenses increases light transmission and reduces reflections, providing a brighter and cleaner image in demanding lighting conditions.
