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 ...
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]
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]
It replaced the 6 megapixel SP-500UZ model that was launched in 2005. It was the last model of the SP-series (Special Performance) that used a 10x optical zoom lens. It was also the last of the larger-sized 10x optical ultra zoom cameras to be made by Olympus, which had been part of the C-series before the SP-series was produced.
A secondary, telephoto lens features 2× optical zoom and 10× digital zoom with an aperture of f/2.4 and optical image stabilization. [54] A Portrait Mode is capable of producing photos with specific depth-of-field and lighting effects. [55] It also has a quad-LED True Tone flash with 2× better light uniformity. [56]
Due to trade-offs in the optical design, superzoom lenses are noted for having poorer optical quality at the extreme ends of their zoom ranges, often due to distortion. [ 4 ] [ 5 ] The longer focal lengths are usually accompanied by optical image stabilization in order to be usable handheld .

The image quality has been lost. No quality is lost however, with the lens zoomed-in optically for the bottom photo. Typically, the digital zoom is not available until the optical zoom has been exhausted. Digital zoom is a method of decreasing the precise angle of view of a digital photograph or video image.
