However, the only differences are some words added on these binoculars. It has an HD letter written on the end of the center hinge and VORTEX on one barrel.


The New and Upgraded Vortex Optics Diamondback HD 10×42 binoculars show a significantly transparent image with better resolution, contrast, and brightness. Similarly, its field of view is 330′ at 1000 m with a 5′ close focus.

Image Quality

The newly designed Diamondback 10 x 42 binocular boasts the HD optical system. This feature offers the same chromatic aberration that an extra-low dispersion glass would provide.

The binocular delivers an excellent edge to edge clarity with the reduction of chromatic aberration. But in suboptimal lights like cloudy days or fog, a slight chromatic variation can be seen. In other words, the outer edges lose a little of their clarity.

However, to provide optimal performance, the binocular lenses are fully multi-coated. They have effectively improved light, minimized light loss and anti-reflective properties.

Furthermore, the multilayer dielectric prism coating offers exceptional brightness and true color fidelity. They have phase-correction coating applied on the roof prism to deliver optimized resolution and contrast.

These coatings are applied with ArmorTek to make the lenses harder and scratch-resistant to protect the exterior optics from oil and dirt.

Construction Quality

These binoculars have the shockproof capability that allows them to withstand the impact and recoil it. They are fog and waterproof as well. It is built using argon gas and later shut with O-ring sealing.

The argon gas helps restrain the optics from fogging when exposed to sudden atmospheric temperature change. Likewise, the O-ring sealing helps to prevent dust and moisture from impaling the binoculars.

With a compact roof prism, you can ensure light path performance without excessive bulk and weight. The HD glass lens element reduces spherical aberration and improves the sharpness and color rendition.

The short close focus distance is perfect for making detailed observations for subjects like insects, bees, birds, flora, fauna, and flower beds. While the wide-angle view helps reduce the distracting appearance of hands.
