Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses (compound lens) used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
A camera lens is an assembly of multiple optical elements, typically made from high-quality glass. [22] Its primary function is to focus light onto a camera's film or digital sensor, thereby producing an image. [12]
In order to more easily compare lens–camera pairs, it is common to use their 35 mm equivalent focal length. For example, when talking about a 14 mm lens for a Four Thirds system camera, one would not only indicate that it has a focal length of 14 mm, but also that its "35 mm equivalent focal length" is 28 mm.
Long focus lenses are relatively simple to design, the challenges being comparable to the design of a prime lens. However, as the focal length increases the length of the lens and the size of the objective increase in size and length and weight quickly become significant design issues in retaining utility and practicality for the lens in use.
A simple scheme for a zoom lens divides the assembly into two parts: a focusing lens similar to a standard, fixed-focal-length photographic lens, preceded by an afocal zoom system, an arrangement of fixed and movable lens elements that does not focus the light, but alters the size of a beam of light travelling through it, and thus the overall ...

Fujifilm FinePix X100. This is a list of large sensor fixed-lens cameras, also known as premium compact cameras or high-end point-and-shoot cameras.These are digital cameras with a non-interchangeable lens and a 1.0‑type (“1‑inch”) image sensor or larger, excluding smartphones and camcorders.
