Web12 de fev. de 2024 · You collect and bend the light from the sun onto a specific point, which is the point of focus on the leaf. A camera lens works the same way, collecting and bending the light onto your digital sensor (or film, if you’re a time traveler from 1995). This is why you never want to point your camera directly into the sun.

A zoom lens is a mechanical assembly of lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed-focal-length (FFL) lens (see prime lens). A true zoom lens (or optical zoom lens), also called a parfocal lens, is one that maintains focus when its focal length changes. Most … Ver mais Zoom lenses are often described by the ratio of their longest to shortest focal lengths. For example, a zoom lens with focal lengths ranging from 100 mm to 400 mm may be described as a 4:1 or "4×" zoom.
