Bushnell PowerView 10x50 Binoculars Review

From first glance, you probably wouldn't think much about these basic, entry-level binoculars, but you'd be wrong. First off, these are Porro prism binoculars that are optically superior to roof prism binoculars in its basic prism function. While Porro binoculars tend to be hideous in aesthetic appeal, the new and improved contemporary style isn't all that bad. You can even get it in the Realtree AP finish which is a bonus.

With its large 50mm aperture, you'll be able to glass out your prey over long distances which is exactly what the hunter needs. At such a low price, you won't be disappointed, but the cost savings had to come somewhere...

While the binocular isn't weatherproof, and it's not exactly impressive when it comes to its close focus distance, it does have an InstaFocus system that allows you to get on target practically immediately.

They're surprisingly lighter than what you'd expect for a full-size Porro prism binocular, weighing in at 25 ounces. Don't forget, you also have the larger 50mm objective lenses to thank for the few extra ounces. To cater to the wee bit of extra weight, the binocular purchase does come with an included carry case, neck strap, lens covers, and lens cloth. With the included accessories, you don't have to tote this beast by hand.

When it comes to checking out what the masses say, it's a two thumbs up with some reservations. The PowerView 10x50 is an excellent glassing binocular with better clarity than what you would expect. However, as it's not weatherproof, you will want to avoid less than ideal weather conditions. Rain can easily penetrate the housing, fog the unit, and render your binocular useless. But, if you're out and about in great weather, you have nothing to fear!

PowerView Binocular 10X50 Q&A:

How are Porro prism binoculars better than Roof prisms?

Fundamentally, Porro prisms have superior assemblies versus roof prisms because all of the glass surfaces are internally reflective. Roof prisms require more expensive and expert engineering to achieve the same, equal optical quality as a Porro prism. However, more money, labor, and engineering are being put into perfecting the roof prism binocular because demand calls for a more compact, weatherproof, and aesthetically-appealing binocular.

What is the Difference between a Porro and Roof Prism Binocular?

The most obvious difference is in its design. You'll notice that Porro prism binoculars tend to look more "bulky" in appearance as their eyepiece and objective lenses are set apart at different distances. Roof prism binoculars maintain a straight line with eyepieces and objective lenses set along the same distance. For more on this and their differences, check out our Porro Prism vs Roof Prism article for the full down-low.

What is InstaFocus?

InstaFocus replaces the traditional center focus wheel for faster and more accurate focusing. Instead of a wheel, the PowerView features an InstaFocus lever that gets in focus fast and easily for bino users of all skill levels.

Can you Mount the PowerView Binoculars to a Tripod?

There seems to be some confusion when it comes to the binocular being tripod adaptable. The PowerView is tripod adaptable. The small round logo with the "B" between the barrels can be unscrewed to reveal the tripod bushing for the adapter.

Will these work well for Low Light Use?

With 50mm objective lenses, you'll have the ability to gather as much light as possible. With an exit pupil of 5mm and multi-coated lenses, you'll only be able to use it for as long as your eyesight allows the darker it gets. If you have excellent vision, you'll be able to get away with some fanatic low light use. If you don't, clarity and usable detail most likely be harder to achieve.

Are there other PowerView models in the Series?

Yes! There are multiple models in the PowerView Series that range from 7X35 to 20X50. The PowerView also comes with zoom models for variations between magnification.

Are all the PowerView binoculars Porro Prism binoculars?

The PowerView Series is large and varied, and it also includes for roof prism models too. If you want to save a few bucks, you could spend less than half for the roof prism PowerView 10X42 binocular.

Do the Binoculars have a Diopter?

Yes, the PowerView does feature a diopter for focusing your right eye. The InstaFocus lever is for central focusing of the left eye. Adjust your binoculars and focus for your eyesight the same way you would for a conventional center focus binocular.

What is BK-7 Glass?

BK-7 glass is a term that Schott AG designated to this type of borosilicate crown glass. It has just a slightly lower refractive index rate versus BaK-4 glass, but it's still a highly reflective source of glass. There are unique identifiers of BK-7 glass that you can learn about with our Glass 101: BK7 vs BAK4 article.

Noteworthy Features:

  • Fast target acquisition with InstaFocus lever
  • High power and large objectives for longer range detail
  • All-purpose binocular for hunting, spotting at the range, and event observation
  • Shockproof with non-slip rubber armor
  • Includes extra accessories
