1. A camera, comprising:
a lens comprising N lens elements L1-LN arranged along a lens optical axis starting with L1 on an object side and ending with LN on an image side, wherein N≥5, wherein the lens elements are divided into two or more lens groups, and wherein two adjacent lens groups are separated by a respective air-gap d1 along the lens optical axis;
an image sensor separated from lens element LN by an air-gap d2 along the lens optical axis; and
an actuator operative to control the air-gaps d1 and d2 to switch the camera between M≥1 operative pop-out states and a collapsed state, wherein in each operative pop-out state m∈{1, 2, . . . M} the lens has a respective effective focal length EFLm and a total track length TTLm, wherein in the collapsed state the lens has a collapsed total track length c-TTL, wherein a minimal effective focal length EFLmin of the M effective focal lengths EFLm is equal to or greater than 6 mm, wherein a maximal effective focal length EFLmax of the M effective focal lengths EFLm is equal to or smaller than 27 mm, wherein the camera has a f number (f/#)<4, and wherein c-TTL<0.8·EFLmin.
