A simple photographic lens may be constructed using one lens element of a given focal length; to focus on an object at infinity, the distance from this single lens to focal plane of the camera (where the sensor or film is) has to be adjusted to the focal length of that lens. For example, given a focal length of 500 mm, the distance between lens ...
The design of telephoto lenses reduces some of the problems encountered by designers of long-focus lenses. In particular, telephoto lenses are typically much shorter and may be lighter for equivalent focal length and aperture. However telephoto designs increase the number of lens elements and can introduce flare and exacerbate some optical ...

A teleside converter lens attached in front of a camera. 2 - Camera lens 1 - Teleside converter. A teleside converter [1] (also known as a telephoto conversion lens or a front mount teleconverter) [2] is a secondary lens which is mounted on the front of a photographic lens to increase the effective focal length of the lens they are attached to.
The catadioptric camera lens' heyday was the 1960s and 1970s, before apochromatic refractive telephoto lenses. [citation needed] CATs of 500 mm focal length were common; some were as short as 250mm, such as the Minolta RF Rokkor-X 250mm f/5.6 (Japan) of 1979 (a Mangin mirror CAT roughly the size of a 50mm f/1.4 lens).

These devices are still common on film sets, allowing shots to be framed without having to use the motion picture camera as a viewing device. Lens finders are camera format specific and require the lenses that will be used in production. They can only be viewed by one individual at a time.
