Skills of using telephoto lens

After a period of exposure to photography, I believe everyone must have the desire to use telephoto lenses. The following are the skills I shared in using telephoto lenses. Let's have a look.

(1) measure light with telephoto.

Let's take outdoor portraits as an example: when shooting, the metering mode is matrix. If the exposure is determined by calculating the overall light quantity with a wide-angle photometric camera, the face of a portrait may become a "black face" due to insufficient exposure. In this case, we can zoom the lens to the model's face and fill the whole picture, then press AE-L to lock the metering, lock the exposure value, and then adjust it back to the wide-angle end for refocusing or composition. This method can ensure the quality of the model.

(2) Use a tripod

When shooting with long focal length, it is easier to blur the photos due to camera shake, especially when shooting in places with insufficient light. Moreover, in many zoom lenses without constant aperture, the maximum available aperture often decreases with the increase of focal length, which leads to the slow shutter speed, so it is safer to use a tripod for long focal length shooting.

(3) Use a hood

The range hood is not only a difference in appearance, but also a practical use. The influence of glare and diffuse light can be reduced, which is more important for telephoto lenses.

(4) Add a range finder.

If you add a telephoto lens to the telephoto lens, you can shoot farther scenery, so it is very useful to shoot the moon and birds.

(5) Use fewer filters

Unless shooting in a harsh environment or using a polarizer to reduce reflection, it is best to use fewer filters on the telephoto lens to avoid internal reflection.

(6) Make good use of the compression effect of telephoto.

The wide-angle end can shoot magnificent scenery, depth and space, while the telephoto can effectively compress the subject and background, making the distance between the subject and the background look "closer". You can try.

(7) Using telephoto to shoot shallow depth of field

The depth of field consists of aperture, focus and focal length. The longer the focal length, the easier it is to take a shallow depth of field. Even if the aperture is not large enough, the background can be blurred a little.

(8) controlling deformation

Wide-angle lenses are prone to barrel deformation, especially at the periphery of the picture. In addition to using post-production technology to improve, we can also use telephoto to reduce deformation.
