There are quite a few of the 12×25 compact roof prism binoculars mentioned, all of which look pretty much the same and also have pretty similar specifications. When you read the product description, they advertise and promise a lot for very little money. Most of them brag with professional, high performance, FMC, low light, night vision, and so on. 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. These binoculars are suitable as all-around binoculars for anyone who wants to see far stuff a little closer, without expecting great optical performance. The low price makes them particularly attractive for beginners or nature lovers who leisurely want to observe wild animals, scenery and nature, or sporting events. 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. 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?
Looking past the dubious claims in online write-ups of these binoculars, as a pair of kids binoculars, or a handy portable pair of compact binoculars for adults, they will likely do what you want them to, for the price. 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.While these optics work well enough during the day, they are not very useful as night-time optics (you’ll want to look into night vision goggles if you want something with built-in infrared illuminator). Nonetheless, color distortions are hardly noticeable during the daytime. These optics are suitable for observing objects at mid-range and long distances. Particularly, they are a decent choice for birding and a bit of stargazing. They may not be as powerful as high-end models, but they provide a far better viewing experience than the naked eye.
To tell the difference hold the binoculars into the light and look at the exit pupil. If it’s a BaK4 glass you can see a beautiful round exit pupil, it is a BK7 prism angular shadowing appear. These Occer binoculars are ideal for beginners and occasional enthusiasts. Since they are lightweight and affordable, they are also suitable for kids. I’ve never heard of the Mksutary brand before, but yes, the budget binocular market is teeming with weird new brands that nobody has ever heard of. 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 foldable eyecups of these binoculars make them suitable for most users, including eyeglass wearers and kids. Moreover, they are made of soft rubber, ensuring you a comfortable glassing experience for prolonged hours. You can easily adjust the eyecups according to your pupil distance, but for some users, these optics’ interpupillary distance (IPD) is not wide enough.
Image Quality
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 size of the exit pupil is the result of dividing the diameter of the field of view by the magnification. For instance, with the 12×25 binoculars, the size of the exit pupil is approximately 2mm. This is low compared to a pair of 8×42 binoculars whose exit pupil is 5.25mm. This number indicates the size of the shaft of light that gets to your eye. The exit pupil also determines the amount of light that gets through the optics. A higher number means brighter images, which is especially useful in low-light conditions. A higher number also means that the object will still be bright, even if your hand shakes. Prisms are essential in binoculars to see an upright normal image. Frequently used types of glass for prisms are the crown glasses BK7 and BaK4, the latter being more expensive but giving the Bino better optical performance in terms of resolution and a bright, color-true image. On the other hand, the Occer 12×25 Compact Binoculars’ edge-to-edge clarity leaves much to be desired. The field of view blurs around the edges significantly, which is no surprise for binoculars in this price range.
When the eyecups are folded in (about 3mm from the lens to the eyecup edge) my eyes are too close and I have shadows on the side field of view, when the eyecups are unfolded, the field of view is fully there. The Occer 12×25 Compact Binoculars are lightweight, portable, and affordable. They have a BaK-4 Porro prism system and fully multi-coated lenses, delivering clear images with accurate color reproduction during the day. At dawn and dusk, they perform reasonably well considering their price. 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. Summary
Construction Quality and Ergonomics
One of the major issues with the Occer 12×25 Compact Binoculars is magnification. Occer says they have a 12x magnification, but this appears to be overstated. If you know your binoculars, you will easily realize that they don’t have a power of 12x. They seem to fall somewhere around the 7x to 8x range. When you google who the manufacturers are, you often come across large companies that manufacture electronic components and all sorts of other gadgets. I have to admit that I was really amazed when I was looking first through the Mksutary binoculars, I expected worse. Of course, it’s nothing earth-shattering, and even if the optical performance leaves a lot to be desired, for so little money, you can not ask for more. Are They Worth It?
