This is a list of smartphones with a telephoto lens that offers a focal length (35mm equivalent) of at least 100mm or "4× optical zoom" with an imaging area equivalent to a 1/3.5″ or larger sensor. Smartphone lenses are often marketed in terms of "optical zoom" [1] relative to the phone's main camera. For example, 120mm is usually referred ...
Lenses marketed as all-in-one usually cover a wide-angle to telephoto range beyond that of standard zoom lenses. [2] There is significant overlap between the two categories with a few exceptions. For example, the Sigma 60-600mm F4.5-6.3 is considered a superzoom lens but not an all-in-one lens. [3] Conversely, the Tamron 35-150mm F2-2.8 is ...
The Sigma 200-500mm f/2.8 EX DG lens is a professional-level telephoto zoom lens made by Sigma Corporation. [1] It is notable for being the first lens with an aperture of f / 2.8 and a focal length of 500mm. [2] This combination allows very distant objects to be photographed at high shutter speeds in dimmer light, compared to other telephoto ...
A zoom lens is a system of camera lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed-focal-length (FFL) lens . A true zoom lens or optical zoom lens is a type of parfocal lens, one that maintains focus when its focal length changes. [1]
Schematic of a conventional and a periscope zoom lens A smartphone with a 5x optical zoom periscope lens camera, recognizable by the rectangular shape of its lens. A periscope lens, sometimes called a folded lens, is a mechanical assembly of lens elements that uses a prism or mirror to redirect the light through the lenses with a 90° angle to the optical axis, as in a periscope.
Hybrid zoom is a concept used in smartphones that takes advantage of optical zoom, digital zoom, and software to get improved results when zooming in further than the lens' physical capabilities. [5] Smartphones with optical zoom have lenses with 3× or 5× magnification.

There is no precise definition of the term, but lenses marketed as "standard zoom" usually cover a range of at least 30mm to 70mm in terms of 35mm equivalent focal length with an optical zoom ratio of 2.5× (e.g. 28-70mm) to 5× (e.g. 24-120mm) — the most common being 3× (e.g. 24-70mm). [1]
