Both models are highly suitable for a novice hunter or a birdwatcher. However, these binoculars are also recommended for general use, and are appropriate for anything not too specific as they are practical, not too heavy to carry, and easy to use.

Nikon VS Vortex Price Comparison

When it comes to these two optics titans, the price is quite acceptable, as everything cheaper is already of questionable quality. The price is more or less the same.

And not that anyone would plan to damage their binoculars, it is still good to know – if the worst does happen – that Vortex offers a 10-year warranty, and Nikon only 2.

Nikon VS Vortex Body Comparison

  • Nikon Prostaff 5 takes on a design that is bigger with fewer details and weighs 630 g, while Diamondback is lighter, at 618 g.

  • The weight and the length (shorter on the Diamondback) are also culprits making it easier to manage the Diamondback with one hand.

  • The two binoculars have a central bridge and central focusing. The rubber on both is strong, thick, well-designed, and the details on the Diamondback fit each other perfectly.

  • Prostaff’s materials have not veered away from the plastic design, as they are plain plastic and black rubber.

  • As for the color, Diamondback is available in hunting green, beautifully designed good quality rubber with nice inscriptions and a logo, which is also engraved in rubber covers.

  • If you are concerned about exposing them to water, both are waterproof, submersible, and perform well with fluctuations in temperature and in the rain.

  • Also, both models are no slouch in other departments either, as both promise to be fog proof, Prostaff with O-ring seals and Nitrogen gas, and Diamondback filled with Argon gas.

Nikon VS Vortex Optics Comparison

  • Both models are right up there when discussing the optics.

  • The Diamondback and Prostaff 5 have a fully multi-coated optical system for maximum light transmission, so they perform well in low light conditions.

  • Diamondback with its 1.5 m of close focus gets more points than the Prostaff 5 since the latter has the same focus of 5 m.

  • Also, Diamondback has a better and wider field of view120 m /1000 m, in contrast to Nikon's 110 m /1000 m, – which helps to follow and focus on fast-moving objects.

  • When observing with the Diamondback, the apparent and the real field of view are both much bigger and wider than with the Prostaff 5.

  • A visible image is extra detailed and bright. However, it seems the central sharpness is slightly better on a Prostaff 5.

  • Sharpness is one of the features that makes Nikon Vortex's competitor. However, we must mention that the difference is absolutely minimal if at all noticeable.

  • That said, the focusing system on both models is central and both have a right-eye diopter setting.

Nikon VS Vortex Purpose Comparison

  • Famous for their day-time and early morning/late evening use, Diamondback would perhaps be more suitable for travelers, since its design is more ergonomically advanced and provides a better grip.

  • But whichever of the two binoculars you opt for, rest assured that both Nikon and Vortex are right up there when it comes to the best and latest advanced binoculars.
