• Objective lens: So, let’s start with the objective lens. Usually, a scope with the 50-80mm lens is available in the market. It’s enough for any adventure lover. Now, if you’re looking for something more powerful then don’t worry! There are also some powerful scopes with a larger objective lens (up to 90mm and more) are available. Always remember one thing, the large lens provides a better visual experience.
• Magnification power: Almost every one of you familiar with the word magnification. We all heard about it in our life. In the case of any scope, magnification is very important. Magnifying power will help you to see things closer. Basically, any scope in the market available with the power from 15x to 60x. You may see in any scopes brochure a number like 15-60x80. It means, with it, you can see an object 15-60 times closer than you would see the object with naked eyes. However, if you’re looking for something with higher magnification then go for more powerful spotting scopes.

• Field of view: So, most of the people get confused when it comes to the field of view. Well, it’s an easy thing. The field of view measured by the width in feet that is visible at 1000 meter/yard. The FOV is essential for better wildlife experience because it provides fast-moving action. Remember, higher magnification power gives narrower F.O.V.
• Close Focus: Close focus always provides the clarity of any closed object. Close focus is essential for watching any object clearly.
• Lens size: Lens size is essential. For explaining it, I’ll take an example of the best spotting scope that I ever used. It is Celestron 52250. In the brochure, it says, 20-60x80. It means, 20-60 magnifying power and 80mm objective lens. 80mm is the size of the objective lens. It’s a powerful lens available in the market, it requires more light to give a better experience. Always keep in your mind, the more light that enters in the spotting scope gives a brighter and clear image. So, if better or best visual quality is your concern then go for any spotting scope that comes with a big lens.
• Prism-Glass and system: Prism glass means the glass a lens made with. The prism glass provides a better and brighter image with high sharpness in the image. Usually, the lens is made with the BK-7 or BAK-4 glass. BAK-4 glass is better than BK-7.
While getting a spotting scope, consider BAK-4 because it’s a high-quality glass that you need. Want to know more about prism-glass? Then check this patent report.
