Slim pop-out tele camera lenses

A lens system for a compact digital camera, the lens system configured to switch from a pop-out state associated with a total track length (TTL) to a collapsed state associated with a collapsed total track length (c-TTL) that fulfills c-TTL<TTL and vice versa by collapsing a back focal length BFL to a collapsed BFL (c-BFL)<BFL and vice versa, the lens system comprising:

• an image sensor;
• and
• a lens with N≥6 lens elements L1-LN arranged from an object side towards an image side along a lens optical axis (OA) starting with a first lens element L1 and having an effective focal length (EFL), the first lens element L1 having a clear aperture diameter DAL1≥7 mm,
• wherein the lens has a 35 mm equivalent focal length (35 mm EqFL) in the range of 30 mm<35 mm EqFL<100 mm and a f number (f/ #)≤2, wherein TTL<15 mm, and wherein 0.9×EFL<TTL<1.1×EFL.
