What's the use of telephoto lens?

The main uses of telephoto lens include long-distance shooting, object detail capture, background compression effect and so on.

1, long-distance shooting

The telephoto lens allows the photographer to shoot the subject from a distance without approaching or touching the subject. This is very useful for shooting wild animals, sports competitions, stage performances and other scenes that need to keep a certain distance.

2, object details capture

The telephoto lens can magnify the distant details and let the photographer capture the tiny textures, expressions and dynamics of the subject. This is very helpful for shooting birds, insects, flowers and other subjects that need to emphasize details.

3. Background compression effect

The telephoto lens has a shallow depth of field and can take photos with blurred background. This makes the subject more prominent, thus creating artistic photos.

When using telephoto lenses, you need to pay attention to the following items:

1, use a tripod or a stable bracket: telephoto lenses are usually heavy, which requires high stability of the camera. When using a telephoto lens, it is recommended to use a tripod or a stable bracket to avoid the jitter problem during hand-held shooting and ensure clear images.

2, pay attention to focus: because the telephoto lens has a long focal length, focusing is more critical. When using autofocus, ensure accurate focusing and track the moving theme, and use continuous focusing mode (AI servo, AF-C, etc. ). If manual focusing is required, please use the zoom-in function to ensure the accuracy of focusing.

3. Control the shutter speed: Because telephoto lenses are prone to jitter, especially in low light conditions, it is recommended to use a faster shutter speed to reduce the blur caused by jitter. According to the focal length and the motion speed of the theme, choose the appropriate shutter speed, or use the stable bracket or anti-shake function (if the camera and lens support it).
