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 ...
The lens is completely stored inside the camera in switched-off state and has a maximum focal length (shown) of 384 mm (calculated equivalent to 35 mm film), minimum is 24 mm, a zoom factor of 16×. The concept of the telephoto lens, in reflecting form, was first described by Johannes Kepler in his Dioptrice of 1611, [ 7 ] and re-invented by ...
Most consumer zoom lenses do not maintain perfect focus, but are still nearly parfocal. Most camera phones that are advertised as having optical zoom actually use a few cameras of different but fixed focal length, combined with digital zoom to make a hybrid system.

A teleconverter works similarly to a telephoto group of a proper telephoto lens.It consists of a group of lenses which together act as a single diverging lens. The location of a teleconverter is such that the image produced by the lens is located behind the teleconverter in a distance smaller than its focal length.
In cameras that save in a lossless format, resizing in post-production yields results equal or superior to digital zoom. [citation needed] Lower-end camera phones use only digital zoom and do not have optical zoom, while many higher-end phones have additional rear cameras, including fixed telephoto lenses that allow for the simulation of ...
It is the first smartphone to feature Nokia PureView Pro technology, a pixel oversampling technique that reduces an image taken at full resolution into a lower resolution picture, thus achieving higher definition and light sensitivity, and enables lossless digital zoom. [3] It was one of the most advanced camera phones at the time of its ...
The camera features a 16 megapixel CMOS sensor and a 21x optical zoom lens, as well as Wi-Fi and 3G connectivity, and a GPS receiver by which the camera can make geotagged photographs. It runs on Android's 4.1 "Jelly Bean" software and it allows for in-camera organizing, editing and online sharing or storage of images and videos.
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.
