1. A lens system for a compact digital camera, comprising:
an image sensor having a sensor diagonal (SD); and
a lens with a field of view (FOV)>60 deg and having a f number (f/#), a lens thickness (TLens), a back focal length (BFL), an effective focal length (EFL) and N≥6 lens elements L1-LN arranged along a lens optical axis (OA) starting with L1 from an object side toward an image side, each lens element Li having a respective focal length fi with a magnitude |fi|, the lens having a pop-out total track length (TTL): wherein TTL<20 mm in a pop-out state and a collapsed total track length (c-TTL) in a collapsed state, wherein the lens system is configured to switch from a pop-out state to a collapsed state by collapsing BFL to a collapsed BFL, wherein SD≥12 mm, wherein BFL>0.15×TTL, and wherein a ratio c-TTL/SD<0.65.
