List of longest smartphone telephoto lenses

This is a list of smartphones with a telephoto lens that offers a focal length (35 mm equivalent) of at least 100 mm or "4× optical zoom" with an imaging area equivalent to a 1/3.5″ (inches) or larger sensor.

Smartphone lenses are often marketed in terms of "optical zoom"^[1] relative to the phone's main camera. For example, 120 mm is usually referred to as "5× optical zoom", because the main camera's focal length is commonly around 24 mm. However, only a few smartphones, such as the Sony Xperia 1 IV and V, include a true zoom lens that offers continuous optical zoom, whereas nearly all smartphones feature a collection of prime lenses interpolated by digital zoom. To fit large focal length the 2010s-era Samsung Galaxy Zoom series of phone-camera hybrids use a retractable lens design, while newer zoom-equipped phones mostly use periscope lenses.^[2][3]

This is not a list of the "best" smartphone telephoto lenses, because many factors affect image quality. For example, the Samsung Galaxy S22 Ultra's telephoto lens outperforms the S21 Ultra's, despite the S22 Ultra's smaller sensor size and shorter focal length, because of hardware and software improvements.^[4]

In a fixed space, greater focal lengths further constrain the size of the image sensor. However some manufacturers have recently been able to improve image quality by using a lens with a slightly shorter focal length but a much larger sensor.^[5] For example, the Vivo X90 Pro+'s 90 mm lens still has a 60% larger effective sensor area when digitally cropped to match the field of view of the X80 Pro's 125 mm lens.^[a]

This list excludes lenses using sensors smaller than 1/3.5″, which seems to be a lower bound for acceptable image quality (most compact travel zoom cameras use 1/2.3″ sensors, which are more than twice^[b] as large).
