A teleconverter enhances the lens function of a camera.
Camera devices store and record images ranging from still photos to moving images like videos or movies. A teleconverter is used to facilitate the lens system used by cameras. Teleconverters allow a camera to zoom in closer to an image for improved picture quality.
Definition
A teleconverter for a camera, also referred to as a tele-extender, is a secondary lens that mounts between the camera and photographic lens. A secondary lens is a lens designed for use with the primary lens of a camera, and is used to zoom-in closer to the image. A teleconverter costs approximately $500 dollars on average.
Function
A teleconverter enlarges the central part of the image received by the objective lens, or optical lens that gathers light from the observed object and focuses rays of light to produce an image. A teleconverter enhances the focal length, or how strongly the lens focuses and defocuses light, of the lens.
Process
Teleconverters consist of a group of lenses that act as one diverging lens. The placement of the teleconverter lens between the camera and photographic lens allows the image produced by the objective lens to appear smaller than its focal length. The image created by the teleconverter, also called a virtual object, is focused farther away than the image obtained by the objective lens, and appears enlarged.
