Do you ever think about why there are so many specifications in binocular models? Why have brands designed binoculars with various magnification levels, different size objective lenses, and several optical categories? Well, the main reason is to satisfy all of the customers by fulfilling their specific needs.
But sometimes so many varieties create confusion, as well as many of you, don’t have enough idea which specification is needed for what purposes. That’s why I am here again.
Today I am going to make a comparison between 2 popular specifications: 10×50 vs 20×50 binoculars. Hope it will be exciting like the previous comparison articles. Let’s begin:
10X50 vs 20X50 Binoculars: A Quick Comparison
Before the broad discussion, I would like to introduce 4 pairs with 10×50 and 20×50 specifications along with all other features. As a result, you will get an idea of the 10×50 vs 20×50 binoculars at a glance.

Now, it’s time to dive into the main discussion on 10×50 vs 20×50 binoculars to decide which one is the best for you. However, the diameter of the objective lens is the same for them. For this, we have to go through every specification except the aperture that I am going to do in this section. Because both have 50mm objective lenses that are good enough to deliver clear and bright images by collecting maximum lights.
The key difference between 10×50 vs 20×50 binoculars is the magnification power. In that case, 10×50 is designed with 10 times magnification capability whereas the 20×50 comes with a 20x magnification system. In general, in outdoor activities, you should choose the 10x magnification to observe detailed and magnified images of the targeted objects.
On the other hand, for long-range shooting or target shooting, you can choose the 20×50 binoculars.
2. Exit pupil
The exit pupil value is another game changer in the decision to pick the 10×50 or 20×50 binoculars. However, the 10×50 has a 5.0mm exit pupil distance whereas the 20×50 has only 2.5mm. Moreover, if you use binoculars for a long time viewing purposes, 10×50 must be on your bucket list. 5.0mm exit pupil distance will ensure a comfortable viewing experience for an extended period.
But 2.5mm exit pupil value may cause eye strains for a long time of observation.
So, if you prioritize the magnification power over eye comfort, then you can choose 20×50 binocular pairs.
3. Eye Relief
The eye relief distance should be greater than 13mm. Also, for the eyeglass wearers, it should be more than 15mm to adjust the focus and watch comfortably. In the above table, only one 10×50 pair has an 18mm exit pupil value. so, I would suggest going for 10×50 binoculars considering your viewing comfort.
4. Field of view
More magnification always magnifies the objects and reduces the field of view gradually. By this fact, you can easily understand that the 10×50 pairs have more field of view than the 20×50. Again, as you can see in the above table, the Bushnell 10×50 and skyGenius 10×50 have 341ft/1000 yards and 367ft/1000yards respectively. On the other hand, the Bushnell 20×50 and UncleHu 20×50 offer 287/1000yards and 170ft/1000 yards only. That is quite less than the 10×50 binoculars and you aren’t able to scan more areas at a time.
So, for long hikes, large stadium sporting events, spying and peeping, wildlife viewing, and birding I would like to recommend 10×50 binoculars. If you need binoculars for long-range target shooting or long-distance viewing, then you can pick 20×50 pairs.
Usually, most binoculars with 8x, 10, 12x, and 20x come with a fully multi-coated optical coating. So, in that case, you can get any of them from 10×50 and 20×50 bino pairs if other properties satisfy your requirements.
The weight depends on the magnification glass, objective lens, material, prism, etc. If you choose a roof prism binocular, it will be lighter than the Porro prism. However, the size of the objective lean plays a big part in terms of weight. But in this 10×50 vs 20×50 battle, both have the same size objective lens. So, weight relays mostly on the magnification power glasses. Typically, more magnification causes more weight. They are difficult to keep steady without a tripod attachment.
So, for rough trails and long hiking, and sporting events, I will go for 10×50 binoculars because mostly their weight is less than 20×50 binoculars. If you want target shooting or a long-time observation session, then you can select 20×50 binoculars with a tripod attachment. As a result, the extra wait won’t bother you.
The price range depends not only on the magnification power, and objective lens, but also on the manufacturing cost, material, prism, lens coating, and many more.
In a general scenario, 20×50 costs more when the 10×50 also comes from the same company. However, the price range can vary from $50 to $1000 based on the features and performances.
