The main characteristics of telephoto lens

1. Narrow perspective
A telephoto lens has a narrow viewing angle, which allows for localized focus of the captured scene and highlights the details and textures of distant objects. This local focusing effect is often used to capture objects such as wildlife or athletes.
2. High magnification
A telephoto lens has a longer focal length, which can magnify distant objects while maintaining image clarity. Therefore, when using a telephoto lens, the photographer does not need to get too close to the subject, making long-distance shooting possible.
3. The shaking is quite noticeable
Due to the longer focal length, telephoto lens are more susceptible to camera shake or unstable handheld shooting, so auxiliary devices such as stabilizers or tripods are usually needed to maintain image stability during use.
4. Perspective compression effect
A telephoto lens can produce a perspective compression effect, meaning that distant objects appear more compact and dense. This effect can be used to create more dramatic visuals, making the distant view more prominent.
5. Relatively large and heavy
Due to the influence of design, telephoto lens are relatively larger and heavier, making them less convenient to carry and use than telephoto lens. In addition, telephoto lens typically require larger front lenses and lens groups to achieve high magnification, and the manufacturing cost is also relatively high.
