The Kenworthy/Nettmann Snorkel Camera System, introduced in 1967 by
N. Paul Kenworthy and Bob Nettmann, uses periscope lenses to allow filming very small
scale models and objects from a very close distance. This system uses a full-size
movie camera with downward-extending periscope attachment, which has a length of and a diameter of . Similar design is used to allow
wide-angle lens protruding from aircraft for
aerial cinematography.
Minolta DiMAGE X introduced in 2002 was among the first
digital cameras to use a folded lens; that design was later adopted on other compact digital cameras. Smartphones use periscope lenses to allow larger
zoom ratios without increasing their thickness significantly. The
Sharp 902, released in 2004, is sometimes credited to be the first mobile phone to feature a (2x variable zoom) periscope lens camera. In 2019, the
Huawei P30 Pro featured a 5x zoom periscope lens. == See also ==
