Most spotting scopes on the market today are refractors that use prisms inside the scope to flip the image in the correct, normal position. Spotting scopes are divided into two categories based on the lens design, including Roof prism and Porro prism. The question people often ask is what type of spotting scopes is better. This depends on the advantages and disadvantages of each type, so depending on your needs, I will advise the appropriate type of spotting scopes. This article analyzes the types of spotting scopes for you to visualize and apply to your case.
Roof prism spotting scopes
Characteristic of this is the type of spotting scopes is that lenses are arranged in a straight line, so the size is slimmer and the design is more beautiful than those of Porro prism spotting scopes. You can recognize this type of spotting scopes by looking at the structure of the spotting scopes and the large lens being aligned with each other.
- It has a compact design: Because the prisms in the spotting scope overlap closely, the objective lens and the ocular lens are aligned, the spotting scope will be smaller, more streamlined, stronger and less bulky than a Porro prism spotting scope.
- It has fewer components than Porro prism spotting scopes, so it is easy to clean up.
- Portability is a perfect feature for someone who frequently travels.
- With a Roof prism spotting scope, image quality is not sharp because the lenses are placed in line with each other, even when manufacturers use lenses with equivalent quality as a Porro prism scope.
- Roof prism spotting scopes have the best quality when the price is high.
- Roof prism spotting scopes tend to lack some fundamental features like interchangeable eyepieces.
This type of spotting scopes is used for bird watching, observing wildlife, and outdoors sports activities.
Porro prism spotting scopes
This type of spotting scopes is usually identified through the lenses being lopsided together.
- In Porro spotting scopes, lenses are generally arranged to have a broader space than in Roof scopes; thereby images are displayed more clearly.
- This type of spotting scopes is the most efficient.
- It is the least expensive, and in fact, relatively cheap.
- Porro-prism spotting scopes are more common, so it is easy to buy.
- The design is quite bulky, so it is not really suitable for those who are always on the go.
- The components are more sophisticated because there are more minor details, so it is difficult to clean up.
Similarly, Porro prism spotting scopes are used for bird watching, observing wildlife, and outdoors sports activities.
