LG’s design employs moving lenses, similar to a classic DSLR camera lens, which retains picture detail, in contrast to most other long smartphone cameras that use image-quality-degrading digital zoom to go beyond their natural focal length. This camera module also employs a folded-optic design, often known as a periscope lens, to reduce total size. As a consequence, the lens has a 4-9x zoom range with real optical zoom in between.
