Telephoto Lens is a specialized type of lens used in photography with the following characteristics:

Long Focal Length: Telephoto lenses have relatively long focal lengths, allowing them to bring distant subjects closer, making them appear larger and clearer. This makes telephoto lenses an ideal choice for capturing distant subjects such as wildlife, sports events, or stage performances.

Shallower Depth of Field: Compared to wide-angle lenses, images captured with telephoto lenses have a shallower depth of field, meaning the background around the subject appears more blurred. This helps to emphasize the subject and creates an artistic background blur effect, making the subject stand out more.

Zoom Functionality: Many telephoto lenses feature zoom functionality, allowing photographers to adjust the focal length within a certain range, thus offering flexibility in different shooting scenarios. This enables photographers to capture subjects at different distances by adjusting the lens focal length as needed.

Compact Lens Size: Despite their long focal lengths, telephoto lenses have relatively compact lens sizes, making them easy to carry and use. This makes telephoto lenses a common choice for outdoor activities such as wildlife photography or travel photography.

Overall, telephoto lenses are known for their long focal lengths, shallower depth of field, zoom functionality, and compact lens sizes, making them an ideal choice for capturing distant subjects. They provide clear, standout images and offer a richer photography experience.

总的来说，远摄镜头以其长焦距、缩小景深、变焦功能和较小的透镜尺寸而著称，是拍摄远距离主体时的理想选择，能够提供清晰、突出的图像效果，并带来更丰富的摄影体验。
