What does focus segment mean?
brief introduction
A lens whose focal length is 1.5 ~ 4 times larger than that of the meter head is called medium focus. Generally, the medium focus lens has the smallest deformation, and it is relatively easy to design it into a super-large aperture, so portrait photography is what the medium focus lens is best at. Generally, the focal length of the title is 1.5 ~ 2 times, which is used to take photos of the whole body and chest circumference. Shots larger than 2 times are mostly used for close-ups, and several shots called "portrait king" in the shot all appear in this focal part.
A lens that is more than twice the focal length of the head is called a telescope head. As the name implies, the telescopic lens can achieve "telescopic" shooting, which is mostly used to shoot sports, animals and so on. The application of telescope lens in scenery film can compress the far and near perspective of the scene.
