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 ...
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]
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]
The EF 70–300mm lenses are a series of telephoto zoom lenses made by Canon Inc. They have a Canon EF lens mount to work with the EOS line of cameras. Four Canon EF telephoto zoom lenses carry the 70–300mm designation. EF 70–300mm f / 4.5–5.6 DO IS USM; EF 70–300mm f / 4–5.6L IS USM; EF 70–300mm f / 4–5.6 IS USM; EF 70–300mm f ...
Sigma 18-200mm/3.5-6.3 DC lens attached to a Canon EOS 400D A Panasonic TZ18 compact digital camera's Leica lens with a maximum focal length of 384mm (35mm equiv.) and minimum of 24mm A superzoom or ultrazoom lens is a type of photographic zoom lens with unconventionally large focal length factors, typically ranging from wide angle to extreme ...
