Product Information

BaK4 was specified in the Mksutary specs, but if you carry out the test just recommended, it seems more like BK7 prisms. There are several factors that determine how far a pair of binoculars can see. With the right binoculars, you can see celestial objects hundreds of thousands of miles away, and you can also see animals a few miles away. A pair of 12×25 binoculars falls in the class of compact binoculars, because the objective lens is less than 30mm (25mm). Factors such as atmospheric conditions, the weather, and brightness will affect how far you can see with the 12×25 binoculars. The Magnification When looking for compact binoculars that perform well in the field, magnification is one of the most important factors to consider other than the actual weight of the product. Models with a magnification of 8x or 10x are the best choices. They strike a good balance between power and weight. 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.

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. You can join aluminium box sections by welding them, usually using TIG welding. It is also possible (and much easier) to use plastic tube connectors, which work by simply inserting into the ends of aluminium square tube or other box sections to create frames or longer lengths. If you have any questions about purchasing aluminium box or square tubing, need advice on an upcoming metalwork project, or you’d like to speak to our sales team, get in touch on 01937 534 318.A 25mm lens is quite small, but sufficient for daytime observation when there is enough light. Less so when the light is rather weak when it is cloudy or you are out in the shady forest. After all, in a 12 x 25 instrument, the exit pupil is also quite small with just over 2 mm, not very suitable for twilight or at night with only little residual light. The so-often advertised “night vision” does not exist with such compact glasses. The Occer 12×25 Compact Binoculars are built for mid- and long-range observations, such as birding and stargazing. Weighing less than 9 oz, they are portable enough for you to carry wherever you go. When it comes to binoculars, size is not necessarily proportional to performance. Sometimes, even the smallest ones are more powerful than the biggest. The Occer 12×25 Compact Binoculars is a great example of a lightweight pair of optics that does a pretty decent job. 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. These Occer binoculars are ideal for beginners and occasional enthusiasts. Since they are lightweight and affordable, they are also suitable for kids.

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. The Occer 12x25 compact binoculars are tiny, even compared to small binoculars like the Celestron Outland X 10x42. (Image credit: Tantse Walter) 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. 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 LensThe right eyepiece has a diopter compensation, it only says +/- on a small scale. The rubber eyecups pop out with a twist by about 1/20 of an inch (6 mm), which is sufficient given the short eye relief. So for me as a non-wearer of glasses (only for reading) viewing with the Mksutary is problem-free and surprisingly comfortable. I’ll have to ask someone who wears glasses how he copes with it. Close Focus

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 Binoculars 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? Take a look at the Celestron Cometron 7x50 binoculars, which we think are some of the best binoculars for kids. They are nowhere near as tiny as the Occers reviewed here but are still considered compact. Comparing it with other binos, ist not 12x, more like 10x magnification. But no matter, for a 25 mm lens an 8x to 10x is enough anyway. 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.In terms of quality, the image is clear enough to see details of objects and follow their movements 300-450 feet away. A decent image at that too. But there’s some aberration and distortion at the edges that will gnaw at pro users’ needs. 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 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 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 The equation calculator allows you to take a simple or complex equation and solve by best method possible.

The 25 times table chart is given below to help you learn multiplication skills. You can use 25 multiplication table to practice your multiplication skills with our online examples or print out our free Multiplication Worksheets to practice on your own. 25 Times Tables ChartI 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? 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. Multiplication Table is an useful table to remember to help you learn multiplication by 25. You should also practice the examples given because the best way to learn is by doing, not memorizing. Online Practice When you google who the manufacturers are, you often come across large companies that manufacture electronic components and all sorts of other gadgets. 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.
