1. A mobile device, comprising:
a first camera having a first field-of-view (FOV1) and a first image sensor; and
a second camera having a second field-of-view (FOV2), an optical lens module including N lens elements L1-LN, a first reflecting element, and a second image sensor,
wherein FOV2<FOV1,
wherein the N lens elements are arranged along an optical axis such that lens element LN is a last lens element facing the second image sensor,
wherein the first image sensor is configured to receive a first light from a first direction through a first optical path between an object and the first image sensor,
wherein the second image sensor is configured to receive a second light from the first direction through a second optical path between the object and the second image sensor,
wherein the first reflecting element is disposed in the second optical path between the optical lens module and the second image sensor,
wherein the second camera has a F-number≤3,
wherein each lens element is denoted Li where 1≤i≤N, wherein each lens element comprises a respective front surface S2i-1 and a respective rear surface S2i, the lens element surfaces marked Sk where 1≤k≤2N, and
wherein each lens element surface has a clear aperture value CA(Sk), and
wherein a clear aperture value CA(S1) of surface S1 is greater than a clear aperture value of each of surfaces S2 to S2N.
