With an eye for the discerning nature enthusiast and seasoned expert, Swarovski 10x50 EL50 Binoculars FieldPro Greenfeature multiple optical technologies to improve image quality and ensure accurate colors in all weather and lighting conditions—especially in low light, such as dawn and dusk or in heavily canopied woods, when many birds and game are most active. Their wide 66° viewing angle and powerful 10x magnification make this optic ideal for medium- to long-range viewing and offer a completely immersive observational experience. The ELs employ a suite of SWAROVISION coatings and technologies including SWAROBRIGHT, SWAROTOP, SWARODUR, SWAROCLEAN, phase-correcting P-coatings, field-flattener lenses, and fluoride glass. These technologies work seamlessly to produce bright and clear high-contrast and high-resolution images with true color fidelity and virtually no distortion across the entire field of view.

Complementing the optical performance is a lightweight and durable magnesium-alloy chassis that can withstand a life in extreme conditions. Their nitrogen-filled optical tubes are water and fogproof to ensure performance in all weather and environments without internal fogging when moving quickly between wide temperature ranges. An ergonomic, wraparound green rubber armor ensures that the binoculars will remain comfortable in the hand during long glassing sessions and helps to maintain a sure grip when it's cold and wet. This version of the EL comes with Swarovski's FieldPro package that features their proprietary rotating pin attachment and adjustment system for the strap that improves mobility and comfort over conventional systems. Included with the binoculars are the FieldPro bag, carrying strap, tethered objective lens covers, and a soft rubber tethered ocular rainguard.

A: We can see the Nikon 10x50 WX IF Binocular (Black) does have an individual focusing system for each Ocular, described in the Overview of those binoculars: "To ensure the sharpest views possible, the WX is built with a helical focusing mechanism on each individually focusing eyepiece. Eschewing the conventional center focusing system not only allows precise focusing for any user, but it also ensures the integrity and longevity of its waterproofing. The helical mechanism moves the eyepieces forward and back without rotating the eyepiece lenses, maintaining a centered optical axis that enables even more clarity and sharpness.
