Swivel lens
A swivel lens is a lens that freely rotates while attached to a camera body. They are used on some compact digital and video cameras (camcorders). These lenses make it easy for a photographer to aim a camera without moving around too much. Swivel lenses come in different sizes and shapes. A swivel lens is also known as a swiveling lens, swivelling lens, and rotating lens. In contrast, swivel LCDs (also known as articulating screen) are displays that freely rotate while attached to a camera body. Usually, the camera body is much larger than the swivelling display. Swivel  LCD devices can be considered as swivel lens devices because the camera body can swivel around the small display; albeit, aiming the camera is more difficult. Most camcorders have a swivel LCD. List of other devices with swivel lens. Cellphones with pseudo swivel lens. Some cellphones have lens that rotate and allow users to take self-portraits but are limited in the angles where the camera can take pictures.
