The features of 30x60 binoculars
30x60 binoculars have a 30x magnification with a 60mm objective lens. This means they can make objects appear 30 times closer than they are with a 60mm diameter lens. This is great for bird watching, wildlife observation, and general use.

How to use 30x60 binoculars:
Binoculars can be used for many purposes, such as bird watching, outdoor activities, or sporting events. Even though 30x binoculars are extremely high magnification for daily use, they are widely used in astronomy (even though you are unlikely to ever see a pair in use).
In terms of mechanicals, 30x binoculars are simply standard binoculars with particularly strong eyepieces, which have a focal length of 3mm instead of 10mm. If you want a binocular with a magnification of 30x60 or greater, you can replace the eyepiece. For an additional charge, some sellers perform this service.
Additionally, these may be image-stabilized binoculars, which are assisted by an accelerometer that detects hand jitter, then mechanically directs a crystal in the light path to negate most of the motion.
What does 30x60 mean in binoculars?
30x60 binoculars are often known as 30x magnification and 60mm objective lenses or even 30x60 binoculars. But what does this mean, and why do you need to know when choosing a pair of binoculars? The first number is your binoculars' power, which is expressed in times. The second number is the diameter of your lenses in millimeters. So, for example, 30x60 means that these binoculars can magnify an object by thirty times 30 and have an objective lens with a diameter of sixty millimeters 60.
Is 30x60 binoculars good?
In short, yes. 30x60 binoculars are good for several reasons. For one, they offer a high level of magnification. This means you’ll be able to see your subject more clearly, making them ideal for birdwatching or other activities where you need to see detail from a distance. You’ll also have an expansive field of view with this type of optic.
Specification Of The 30×60 Binoculars
Binoculars are generally available in different designs and specifications. The main parameter in the design of binoculars is their power, specified by two numbers. The first number is the magnification, while the second denotes the diameter of the objective lens in millimeters. So, a pair of 30×60 binoculars means that it has a 30 times magnification power and an objective lens of 60 mm diameter.
There are two types of 30×60 binoculars:
30×60 Lens Coating and Prism Coating.
30×60 Lens Coating:
The lenses on binoculars with prism coating are treated with a special anti-reflective material that helps reduce glare and improve light transmission. This results in a brighter, clearer image. The downside is that these binoculars are usually more expensive.
30×60 Prism Coating:
Binoculars without prism coating don’t have this special lens treatment, but they’re usually less expensive. Some people may prefer them for that reason. They also work better in the daytime because their lenses don’t absorb as much sunlight.

30×60 Eye Relief and Exit Pupil Size:
When you look at the number 30×60, it is easy to assume that this is the binocular’s magnification and objective lens size. However, this number refers to the eye relief and exit pupil size. Eye relief is the distance between your eyes and the binocular lenses where you can still see the full image. The exit pupil is the diameter of the light beam that hits your eye when you look through the binoculars.
