Optical Performance

The Vortex Diamondback 8x28 binoculars have dielectric fully multi-coated lenses and prism which enhance light transmission for more clearer and brighter images. they produce impressive images which look somewhat like high definition images. You might only notice slight chromatic aberrations at the edges of the image in white or bright backgrounds.

These binoculars have one of the widest field of view (360 feet/1000 yards)  in their class which makes them very efficient at glassing your surroundings to identify your target.

The Vortex Diamondback 8x28 has a close focus range of 13.1 feet. This makes them not your ideal birding binoculars. Because you might not be able to get a fuller picture of close range smaller creatures like the butterflies, dragonflies, etc.

In the side of brightness, due to the smaller nature of the objective lens size of these binoculars been 28 mm, they are not suitable for low light conditions viewing. Since they won’t be able to gather enough light from the target to create a bright image.

So if you are considering getting them for natural bright light usage, then I think they are one of the best in their category.
