Claim 4:
5. 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 di along the lens optical axis;
an image sensor separated from lens element LN by an air-gap d2 along the lens optical axis, the image sensor having a sensor diagonal SD between 7 and 20 mm; 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 and to focus the camera on an object at an object-lens distance u of less than 30 cm, wherein in each operative pop-out state m∈{1,2, . . . } the lens has a respective effective focal length EFLm and a total track length TTLm, wherein in the collapsed state the lens has a total track length c-TTL, wherein a minimal EFLmin of the M effective focal lengths EFLm is equal to or greater than 7 mm, and wherein c-TTL<0.65·EFLmin,
wherein the actuator comprises a guiding and positioning mechanism based on a kinematic coupling mechanism.
