Sport ED Series
Design Concept:
The design concept of the sports series binoculars is crafted for the Asian Games, drawing inspiration from sports arenas. The design of the interconnecting part between the two barrels and the lens cap insertion port is based on athletic fields, aiming to seamlessly blend the vitality of sports with the excellence of technology. Such a design not only demonstrates respect for sports but also allows users to feel as if they are immersed in the excitement and energy brought by sports while enjoying natural landscapes.
Optical Performance
Extra low-dispersion (ED) glass helps to correct chromatic and spherical aberration to improve clarity and sharpness with accurate color representation without ghosting or halos— especially at the edges of the field of view.
Anti-reflection multi-coated optics improve light transmission and contrast and provides an accurate color rendition.
Phase-correcting prism coatings eliminate internal interference to improve color and contrast.
Dielectric prism coatings boost internal prism reflectivity to greater than 99% to maximize light transmission through the prism with minimal loss and diffraction.
Construction Details
O-ring sealed and argon filled to be waterproof and resistant to internal fogging when moving through extreme changes in temperature or environmental conditions.
The well-balanced, ergonomic industrial design magnesium alloy body protects the binoculars from damage without weighing you down.
Rubber-armored exterior offers impact protection while providing a slip-resistant grip.
Comfortable eye relief improves viewing comfort and reduces eyestrain during long glassing sessions.
Warranty
All binoculars from Eyeskey come with Lifetime warranty.

Great binoculars. Clear view, easy to focus, and able to focus closeup.

The image clarity of the binoculair is above expectation with low light conditions as well bright sunlight, objects of over 40km distance are clearly visible, although keeping the binoculair stable when using for long distance observation can be a challenge when used without a tripod. I personally make use of and can recommend the Neewer 200cm Camera Tripod with 360 Degree Swivel Center and adjustable angle which enables stargazing and long distance observation with ease.
12x50 model: Optics are good, but a bit on the darker side. No notable CA or purple fringing. Built quality feels on par with my Vanguard 8x42 ED's. But as another reviewer noted, the distance between eyepieces even at its most squeezed position is too much for my 57mm pupillary distance.
Nice binoculars. Good value for the quality.
However, the most narrow position isn’t narrow enough to give me the correct pupil distance. As a result I get the black halo effect at the edges.
Too bad. I want to keep these but they’re going back.
