Frequently Aksed Questions about Zen-Ray Binoculars

Q. What's the difference between ZEN ED2 and ZEN ED binoculars.

A. The new ZEN ED2 is built upon the original ZEN ED platform by incorporating several advanced technologies on three models – ZEN ED2 8x43, 10x43 and 7x36.

The backbone of the ZEN ED2, prism coating, is significantly enhanced with the state of the art dielectric prism coating to maximize the total light transmission.  The coating was engineered with 40+ layers of nanoscale film with precise thickness control. Unlike metallic prism coating, our dielectric coating offers a superiorly flat curve, averaging 99% rate of reflectivity throughout visible spectrum range.  As a result, the users are able to enjoy a brighter image with a better balanced color tone.  A proprietary new Speed-Dial TM focusing mechanism with 30% faster focus rate is also developed exclusively by Zen-Ray to allow users to better track fast moving objects out in the field. The ZEN ED2 binoculars are designed to use under the most adverse weather conditions with its Argon noble gas charged waterproof chassis and new build-in CrystalView TM oil and water repellent coating

Q. What's the major difference between VISTA and ZRS (SUMMIT) binoculars.

A. Both models are featured with fully multi-coated optics, which means every glass/air interface has been coated with multi-layer anti reflection material. As a result, they can achieve 99.2-99.5% transmission rate for each glass surface. In addition, they both are waterproof/fogproof with inert gas charged/o-ring sealed.

VISTA is designed to compete with mid-priced ($200-$350)binoculars on the market, whereas ZRS is designed to exceed optical performance of more expensive binoculars ($500-$700). You will see a lot of premium features included in the ZRS package, such as magnesium chassis, Argon gas filling, Locking diopter, phase coating. ZRS is designed to improve the edge to edge sharpness so a true flat viewing field can be obtained.
