Abstract
Folded digital cameras comprising a lens including a plurality of N lens elements marked Li where 1≤i≤N and an optical path folding element (OPFE), wherein a first lens element L1 faces an object side and a last lens element LN faces an image side, wherein at least one of the plurality of lens elements is located at an object side of the OPFE and has an associated first optical axis, wherein at least one other of the plurality of lens elements is located at an image side of the OPFE and has an associated second optical axis, wherein the lens has an effective focal length (EFL) and a f-number (f/#), and an image sensor having a sensor diagonal (SD), wherein the EFL can be varied continuously between a minimal EFLMIN and a maximum EFLMAX by independent movement of lens elements and of the OPFE along the second optical lens axis, and wherein EFLMAX/EFLMIN>1.5.
