Prostaff 7 series consists of 8×30, 10×30, 8×42, 10×42 models, so the basic purpose was that in addition to standard-sized 42mm-dia models, 30mm-dia models that are easy to carry for everyone are available, providing high optical performance in a compact body. Thus under these conditions, it is often impossible to notice a difference in brightness between the views of equal quality 8x42 and 10x42 binoculars. Nitrogen filling prevents fogging while the design is slim and simple. An extendable eye relief provides comfort for spectacle wearers, as do a dioptric adjustment ring, flip-down lens cap, and a new strap mount. A 15-year warranty provides extra peace of mind. I'm also interested in the Prostaff 7 10x42 as I see it has better coatings and is slightly cheaper, but the 10x50 would better used for astrnomy. Also, Chromatic Aberration is present in all the models mostly at the center, but it is somewhat to a lesser degree in the 7s series.

Generally, these binoculars perform well in broad daylight. You will hardly see any noticeable image quality distortion. There’s minimal fringing with these, only a mild bit of chromatic aberration–something that most casual users will never distress about.For those who not sure what these numbers are. These are the numbers you see written on the binoculars. Either on the focus knob or on the body of the binocular. For example, the binoculars I am comparing here are the and Nikon Prostaff 3s 8×42, Nikon Prostaff 3s 10×42, Nikon Prostaff 7s 8×42 and Nikon Prostaff 7s 10×42 models. So those two numbers stand for the magnification and the objective lens diameter respectively. Whether you’re an outdoor enthusiast or simply looking to get a better view of a game when you go to a sports event, a decent pair of binoculars can provide you an awful lot of pressure.

Released somewhat recently in 2018, these mid-range Nikon binoculars feature lower magnification capabilities but have a generous objective lens diameter and roomier eye relief than other models. We reviewed the Nikon Prostaff P3 8x42 which is very similar to the 3S 10x42 noted here and gave them four out of five stars for their premium-finish and excellent clarity. First up, you'll need a binocular with a large objective lens — this is the glass end that points towards the sky. Large objective lenses mean more light particles (photons) heading down the barrel and into your eyes, so you should get bigger, brighter views. All of Canon’s current range of binos have the ‘IS’ suffix in their model name to denote the fact they’re image-stabilized binoculars. This battery-operated option enables you to get a wobble-free image by just pressing a button on the binoculars – and the stabilizing effect is both instant and jaw-dropping.Equipped with an Eco-Glass optical system, these binoculars offer pretty good image quality. Its roof prism surfaces are coated with high-reflectivity silver alloy, ensuring reliable brightness and clarity. Further optimizing image quality are the multi-coated lenses, which provide exceptional light transmission. Generally, they perform really well in broad daylight. Thanks again everyone for helping me solidify my choice. I’m going to go with the Prostaff 7s 10x42. While it has gained its reputation as an industry leader for its binoculars and cameras, Nikon’s contributions to the industry go beyond these products. It constantly innovates in the fields of digital imaging technology and sports optics, serving its consumers’ best, evolving interests.

This model offers a three hundred and sixty feet field of view at one thousand yards. Ocular Rain Guard Live Science tests a huge and diverse range of products, from Legos to binoculars, and from exercise bikes to dehumidifiers. Depending on just what we're reviewing, a product will be subjected to an array of different tests relevant to its purpose and use. This may include in-lab benchmarks, extensive use in our test centers or thorough road-testing in real-world conditions. Thus if you get more image detail or are able to see further with a 10x binocular, you may be then be thinking why would you the ever opt for a lower-powered 8x binocular instead? Users of the two the Nikon Prostaff 7s binoculars said the Prostaff 7s binoculars are more pleasant and impressive to look through. This is because the Nikon Prostaff 3s showed more on-axis chromatic aberration whereas the Prostaff 7s showed lateral chromatic aberration. Lens and Prism Coatings In a nutshell, then, the Nikon Aculon and Prostaff ranges are the ones to seek out if we want to keep our budget low yet want a reliable and simple-to-use binocular – with some Aculon binoculars being a 10th of the price of range-topping Monarch examples – while the aforementioned Monarch family is the one to investigate if we demand the very best and have the cash to invest.While Prostaff 7s is perfect for hunters, Prostaff 3s is designed for bird watchers and tourists who like observing wildlife. Overall, the Prostaff 7s and 3s are suitable for a wide range of applications. Whether you’re going sightseeing in the Grand Canyon, attending a live concert or watching a football match, these optics equipment will really come in handy. Similarities and differences Similarities

With a smaller objective diameter, you won’t have too much weight weighing you down especially if you’re carrying hunting gear. But if you don’t mind the additional weight, a 42mm is the most preferred. Not only does it offer higher magnification, but it also boasts a wider field of view (FOV). This makes it possible to sell at a lower retail price compared to binoculars with similar features from other companies. Final Verdict That said, the Prostaff 7s has one extra feature that makes it superior to 3s model. The prisms on the 7s are reinforced with phase correction coatings that further enhance resolution. As both 10x42 and 8x42 binoculars have 42mm objective lenses and assuming they use the same quality glass and coatings, the light-gathering ability between the two will be the same. Best binoculars for horse racing and other sports: Sports tend to happen during the day, so a bright objective lens is less of a concern. Something like an 8x30 will hit the spot, as the 8x magnification should be plenty to see what's going on from the stand. There's no point getting something big and heavy if you don't need it!

Next, a stargazing binocular should have generous magnification. We'd recommend upwards of 10x and ideally 15x or 20x plus. The greater the magnification the more detail can be observed in smaller constellations, asterisms, galaxies, globular star clusters and other celestial bodies. You’d be surprised to learn that many pairs in this price range come equipped with a single lens coating, but the manufacturer has shown us that you don’t have to spend hundreds of dollars to get a pair of binoculars that offer top of the line optics quality. Basically, the more lens coatings, the better the image quality. Models with a single coating aren’t recommended for low light conditions. However, the lenses in these binoculars have several layers of lens coating, which is what makes them so versatile.
