A type of camera lens construction. Floating element lenses move certain groups at close focussing distances, thereby permitting the lens to focus sharply at a closer distance than it would otherwise. The lens design also helps minimize certain forms of aberration at close focus distances. Nikons name for this is close range correction (CRC). Hasselblad lenses with this feature are marked as FLE for Floating Lens Element.
cf. close focus distance, close range correction, element, group.
