If you plan on heavy binocular use and want peace of mind from a Limited Lifetime Warranty, we recommend purchasing from a big brand like Celestron or Nikon. The specs and claims from Occer don't quite match up and we would only know the real durability of this pair after a few months of constant use. The Occer 12x25 compact binoculars are tiny, even compared to small binoculars like the Celestron Outland X 10x42. (Image credit: Tantse Walter) The lenses are fully multi-coated. This reduces the reflection and ensures brighter images. Anti-reflective lens coatings are essential, otherwise, modern binoculars with their many lenses would lose too much light so that everything would look quite dark through it. The hinge of the middle bridge moves smoothly and evenly, by about 35 degrees. This sets the interpupillary distance from 2.36 inches (6 cm) to a maximum of 2.95 inches (7.5 cm), which fits most people.

These optics have all the essential features to make your outdoor adventure enjoyable and hassle-free— all at an affordable price point. These features include BaK-4 Porro prism, powerful magnification, wide field of view, and decent low-light performance. The thing is amazingly robust and can be used on excursions, hikes, or in your free time. The model is small, very light, and extremely easy to stow away, so you can always have your binoculars with you. SummaryWhen you hold the binoculars in your hand for the first time, the thing is more compact than expected. Well, it’s 12×25. It’s very light, just under 10 ounces, and has grippy rubber armor on what appears to be a polycarbonate chassis. Mechanics magnification is quite a lot for small compact binoculars and might bring stability issues. It could be difficult to hold the thing still so that the images don’t blur, which is difficult because of the low weight. At 12x magnification, this pair of binoculars brings the image 12 times closer than an unassisted eye would. Because the magnification of this pair of binoculars is higher than 10x, it makes steady viewing a challenge. If you are moving, such as on a boat or in a moving vehicle, the binoculars might not be steady enough to allow you to view far away images. Field of View However, the optical performance of binoculars depends not only on the magnification and the lens diameter but also to a much greater extent on the quality and processing of the optical glass.

In terms of optical performance, sharpness, and contrast, the image quality is not nearly as good as in somewhat more expensive binoculars. But what can you expect at such a low price?In the close range, I was able to bring it into focus at objects that are about 12 feet away, after seemingly endless turning of the focus wheel. Collimation For a powerful pair of binoculars, these optics are surprisingly compact and lightweight. It is rare to encounter models that claim to have a 12x magnification and weigh less than 9 oz each. The problem with this combination is that it is challenging to stabilize the optics. Shaking will likely trouble you more often than you’d like. In terms of quality and performance, these optics are quite average. They provide bright and clear images with minimal color distortions, especially when there is good lighting. Thanks to the easy-to-use and strategically placed focus wheel, obtaining a laser-sharp focus is also easy.

We found the Occer 12x25 compact binocular eyecups a little too soft and they folded even with the slightest pressure applied. (Image credit: Tantse Walter) An exact specification regarding the eye relief was not given in the product description either. I then just allowed myself an approximate estimate. With the help of a strip of paper and a light source, I get about 10 to 12 mm. Nevertheless, I think that you really can’t expect much for so little money, the thing isn’t even waterproof, and that is something you would want. For just a few dollars more you could get better instruments from well-known manufacturers. Don’t fall for all the buzzwords like high power and night vision, touting the product. 8x to 10x magnification is enough for a 25 mm objective. On a general note But they all have one thing in common, they bring products on the market that are really unbeatable cheap, and often there are even tons of accessories included. Now let’s see if that’s any good. Mksutary 12×25 Poro Prism BinocularsLens coatings also play a role since they optimize the binoculars’ ability to gather light and prevent glares. Fully multi-coated lenses are preferable for birding because they have multiple anti-reflection coating layers on all air-to-glass surfaces, giving you the best possible views of your favorite tiny creatures. Field of view refers to width at a distance. For example, if you are pointing the binoculars at something 1000 yards away, you can see an image through them that is 90 feet wide, but anything wider than that you wouldn’t be able to see. Higher magnification means a smaller field of view. At 12x magnification, the field of view narrows significantly, making it difficult to locate small and mobile objects when you are scanning from hundreds of kilometers. The eyepiece design plays a role in determining the field of view as well. The Diameter of the Field of Objective Lens The same applies to the color fidelity of the image. With everyday observations, the colors appear a little colder through the binoculars than in reality. But in no way disturbing. These Occer binoculars are ideal for beginners and occasional enthusiasts. Since they are lightweight and affordable, they are also suitable for kids.
