Definice a Význam "telephoto lens"

What is a "telephoto lens"?

A telephoto lens is a type of camera lens designed to capture distant subjects with greater magnification and detail. It has a long focal length, allowing it to bring faraway objects closer and fill the frame with them. Telephoto lenses are commonly used in wildlife photography, sports, and portraiture, where getting close to the subject is challenging. They also help to create a shallow depth of field, making the background appear blurred and emphasizing the subject.
