Product Information

As for the eye relief in binos, it’s the maximum distance from the ocular lens that users can see the entire viewing angle. This is especially crucial for people who wear glasses as sometimes they can only see part of the image in the ocular lenses. As such, binos like the Pentax SP are better suited for them as the large 20mm eye relief ensures they can see the entirety of the whole image. However, if you don’t wear glasses and don’t mind pressing your face to the binos, the short eye relief should work just fine. Exit Pupil describes the refractive index as a measure of how much light rays bend as they pass from one medium to another. As for SK15 glass, it has a higher refractive index than both BAK-4 and BK7. However, the light dispersion falls between the two. SK15 prisms aren’t as common in the market as the other two. Ultimately, the upsides and downsides of these prisms and the types of glass they use should help you determine which binos to buy. Eye Relief The trade-off here is a slightly narrower field of view (of about 4.8°), which makes them slightly less than ideal for using at night to search star-fields and constellations in the night sky. However, in practice the Celestron Nature DX ED 12x50 performs really well at night, with the Andromeda galaxy looking sharp and well defined. Ditto the crescent Moon, which looked clean with no sign of purplish fringing – thanks to that ED glass. The turn-and-slide rubber eyecups allow you to adjust the eyecups to fit your eyes perfectly. It features an 11.5mm eye relief distance as well as a 56-72mm interpupillary adjustment range also. You will be able to enjoy extended periods of viewing without any fatigue.

Despite the larger 70 mm objective aperture, the higher magnification of 15x reduces the apparent field of view to 4.4 degrees, compared to typical 10x50s or 12x50s that provide a degree more. With the lightweight construction of the CL Companion binoculars and the impeccable build quality, you can be sure your investment will withstand the test of time, which is what you would expect as these are far from cheap. But I say you get what you pay for and the optical quality of these binoculars is possibly the best on the market.Cameras Mirrorless Cameras DSLR Cameras Digital Compact Cameras Video Cameras Lenses Mirrorless Camera Lenses DSLR Lenses Lens Filters Lens Accessories

Binoculars largely come in two varieties when it comes to coatings: they’re either fully coated or multi-coated. In both versions, all lenses, glass surfaces and prisms feature at least one layer of magnesium fluoride or calcium fluoride. Binoculars with multi-coated optics are the most superior kind you’ll be able to find on the market, with at least one of the surfaces featuring several layers of anti-reflective compounds. Which binoculars are best for astronomy?

The Leupold BX-4 Pro Guide is easily one of the best 12×50 binoculars, thanks to the Leupold BX-4 Pro Guide coating system. This works in conjunction with the roof prism design and the superior calcium-fluoride lenses to provide optimal image quality. The SkyMaster 15x70 binoculars have a notable advantage. They gather more light and provide higher magnification, enhancing the clarity of objects that might appear blurry in less powerful binoculars. While there is some softness and blurring at the edges of the view, a common trait in affordable models, these binoculars offer a comfortable 0.7 inches (18 mm) of eye relief, making them suitable for people who wear glasses. Celestron Cometron 7x50Their small size and light weight (1 lb 11 oz) let you use them all day, yet you can still hand-hold them comfortably after sunset and long into your dark night of sky-watching.Considering what and who they're for, for the price, they're hard to beat. ★★★★

The Celestron Nature DX ED 12x50 uses a roof prism design whose primary advantage is a space-efficient, more portable design. Essentially two tubes attached by a hinge (as opposed to the L-shaped optical engine between the tubes on a pair of porro prism binoculars), the Celestron Nature DX ED 12x50's tubes are nitrogen-purged to help reduce the threat of internal fogging. At 11-inches (280mm) in length and weighing 3 lbs (1.36kg), we found in our Celestron SkyMaster Pro 15x70 binocular review that they certainly have a lot of heft, but using them handheld isn't impossible. You'd be most comfortable if you mounted them to a tripod. However, because of their high magnification, the views of the moon are absolutely breathtaking. We were especially impressed by the stereoscopic viewing of the lunar surface.

These binoculars have a wide field of view, which makes it great for you to see everything in your surroundings. They also have long eye relief, which means you can keep them focused on your target without having to strain your eyes. With a 4.16mm exit pupil distance, these binoculars provide an immersive experience when observing wildlife or scenic landscapes.

Not all 12×50 binos are built the same, and the prices available are pretty indicative of this. The price disparity stems from differences in the features, and we look to break them down below so you know how influential they can be. Prism System Porro and roof prisms are the two types of prisms you can usually find in binoculars BFULL has made a budget-priced set of binoculars that performs better than some models we tested that sell at much higher prices. We appreciated the important features of the BFULL binoculars, such as the fully waterproof housing that allows you to take them into any weather and not worry about their longevity. The filled nitrogen means they don’t fog up either, so you’ll always be able to see your target. Despite being priced affordably, the lenses on these binoculars are still very high quality and give a bright and crisp image. Low-light vision is also possible, but it wasn’t one of the stronger performers in that department. It achieves this via Nikon’s Field Flattener Lens System, which in tandem with the Monarch HG’s 30mm wide field of view helps maintain sharpness right to the lens’ periphery. Also impressing is its water and fog-proofed build, while focusing is achieved via a large centrally located wheel, which makes operation unbelievably smooth, particularly when panning with subjects. This Nikon’s sharpness can be fine tuned for spectacle wearers too, via a dioptric adjustment ring on the right eyepiece. Celestron’s Nature DX ED 12×50 binoculars are a great choice for birders and nature lovers alike. With 12x magnification and 50mm objective lenses, these binoculars provide bright, clear images. You will get the maximum light collection for the bigger aperture lens. Size and weight also matter. Some binos are large and heavy, while others are small and lightweight. The former may be harder to carry, but they could also have some extra benefits due to size, so ruling them out altogether may not be ideal. Focus SystemFor most people, handholding 12x binoculars is not a problem. The magnification may be higher than what you get with most standard binos. However, it doesn’t introduce enough shake in the images to make a tripod necessary. Our verdict
