Kit lens

A kit lens is a "starter" lens which can be sold with an interchangeable-lens camera such as a single-lens reflex camera. It is generally an inexpensive lens priced at the lowest end of the manufacturer's range so as to not add much to a camera kit's price. The kit consists of the camera body, the lens, and various accessories usually necessary to get started in SLR photography. A kit lens can be sold by itself outside of a kit, particularly the ones that are moderately expensive; for instance a kit lens included in a prosumer SLR kit is often marketed as an upgrade lens for a consumer SLR. In addition, retailers often have promotions of standalone low-end SLR bodies without the lens, or a package that bundles the SLR body with one or two more expensive lenses.

Originally kit lenses were of normal focal length; more recently kit lenses tend to be inexpensive zoom lenses that range from medium wide angle to mid telephoto for added versatility. Prime lenses are generally faster (smaller f-number), but the change to zoom lenses has usually meant that a slower (higher f-number) lens is used. This is because in most cases prime lenses are faster than comparably priced zoom lenses. However in most cases the inclusion of an inexpensive zoom lens is to maintain a low entry price and maximize usability for the beginner photographer.

Higher-end SLRs generally do not come with a lens, as the buyer is assumed to already own lenses or to plan to purchase them separately.

Digital single-lens reflex cameras

Because of the crop factor, kit lenses for APS-C format cameras (like Canon EF-S and Nikon DX) have shorter focal lengths, to get the same field of view.
