400x magnification

The same principle apply to stereo microscopes, a 10X eye piece combined with a 4X objective lens will produce 40X magnification. Some stereo microscopes equipped with continues zoom objective lens with magnification from 0.75X – 7.5X. The total magnification will be 7.5X to 75X when combined with 10X ocular lens.

To calculate the total magnification of the compound light microscope multiply the magnification power of the ocular lens by the power of the objective lens. For instance, a 10x ocular and a 40x objective would have a 400x total magnification.

100X

Your level of magnification will deal specifically with the working distance and field of view for your magnifier. For example, a 5x magnification indicates a field of view of 1.5”.

FOUR TYPES OF MAGNIFICATION

• Relative-size Magnification.
• Relative-distance Magnification.
• Angular Magnification.
• Electronic Magnification.

At 5 power (5X), field of view is about 1.5″. At 10 power (10X), it is about 0.5″. Usually, it is best to use low power for scanning larger surfaces and high power for small areas.

The universal consensus is that the 10x has to be better because of its higher magnification. Many hunters, shooters, and birdwatchers argue that being able to bring an object 10 times closer versus 8 times closer is the most important aspect of a binocular.

In most binocular models, the eye relief is greater on the 8×42 version than on the 10×42 version or the 8×32 version is there is one. As the sampling below shows, this is not always the case. In the Leica Ultravid HD, the 10×42 has slightly longer eye relief than the 8×42.

For most situations, users should look for binoculars from 7x to 10x power. Theatergoers should choose something in the range of 3-5x, depending on your seats; sports fans will be happy with a 7x model; while big-game hunters would need 10x or higher for long-range observations.

The magnification power of a 12×50 is 12 times magnification (12 times larger than normal unaided vision). So the “zoom difference” would be an increase of 20% in the magnification from a 10×42 to a 12×50. The magnification power of a 12×50 is 12 times magnification (12 times larger than normal unaided vision).

40×60 MAGNIFICATION – See things 40X closer and Get Clearer and Brighter range of view with 60mm lens – The most powerful hand held monocular available in the market today, that also provides the most pleasant and clear view. Multicoated optics guarantee superior light transmission and brightness.

The 10X50 has bigger objective lenses, and does a little better for brightness and focus around the edges. The 10X42 may have better focus at the center, Advantage: 10X50 – albeit you’ll only see that advantage in low light conditions, like early morning or early evening.

At such a long distance, the difference is not great. But when you start getting in close, FOV becomes an important factor. So, when you require more FOV, go with a 10x binocular. If you need distance, then the 12x binocular is for you.

10x is usually the max recommended limit for hand held. Mounting 10x gives much better views. Some claim to be able to hold 15x.

Which is the best magnification for binoculars? For birding and hunting, 10X and 12X are better. However, for stargazing, you need to go for 12X or even 14X.

7×50 binoculars will give you an exit pupil of 7mm, which is the largest you want to use. 10×50 binoculars have a 5mm exit pupil, which is even better. If you are over 40 years old, your maximum dilated pupil size at night will probably be closer to 5mm.

The 10×50 can be used handheld but 20×50 will need a tripod. After using 10×50 Binoculars for if you want more magnified views you can go for 20×70 binoculars. Even the most experienced astronomers have a 10×50 along with the telescope to be able to quickly find objects. I believe a 10×50 is great.

When people think about 12 power binoculars I believe there is a misconception that you cannot glass with them solely using your hands. 12 power binoculars are still light enough for hand holding and they don’t have that much narrower of a field-of-view (FOV), which could cause you to be extra shaky.

If you are an avid hiker, bird watcher, or enjoy being outdoors and are in need of a good pair of binoculars to see the game, then 10×50 binoculars are a good option. These binoculars include a five-degree exit pupil and a superior low-light performance level for brighter vision.

These Bushnell 20×50 are awesome! They are super crisp, and believe it or not, they are actually really easy to hold steady considering the magnification. They have slightly more weight than, say, a small compact pair of bino’s, but these are great. Worth every penny.

8x

The monocular gives you half the binocular, less than half the weight (there is no bridge), and often a proportional cost savings. The disadvantage is that one-eye viewing is more tiring than viewing with both eyes, and you lose the stereoscopic advantage of the binoculars.
