The Zeiss Conquest 10 x 42 HD Binocular has a higher magnification that allows concentrating on a more focused subject for greater detail. The golden-mean objective size provides sufficient light gathering ability for the twilight zones of dust and dawn without the added bulk of an oversized objective. Water sports and rainy days won't leave this item in the car or backpack. It is waterproof to 13' and nitrogen filled to provide fog-proofing and inhibit any condensation build-up.
Zeiss high quality optics plays a major role in the superiority of this binocular. Multi-layer coating reduces light loss and glare due to reflection offering a brighter, higher-contrasted image and light transmission of up to 90%. HD (High Definition) glass reduces the chromatic aberration that appears as unwanted "fringes" of color between dark and bright parts of an image. The LotuTec coating protects the lenses from dust and water. Rain just slides right off the exposed glass.
A large center focusing knob is easily accessible in all kinds of weather. The twist-up eyecups feature is a comfort for eye and sunglass wearers and the dioptric adjustment ring allows for individual eye differences. The close focus of an up-front 6.6 ft/2 m means being able to catch the detail in that fluttery butterfly's wing before it disappears into thin air.
