1. A dual-aperture camera, comprising:
an integrated camera that comprises a Wide camera unit having a Wide lens unit with a field of view FOVW and having a total track length TTLW and an effective focal length EFLW, and a Telephoto camera unit comprising a Telephoto lens unit with a Telephoto field of view FOVT, a total track length TTLT and an effective focal length EFLT,
wherein the TTLT includes a glass window,
wherein a ratio TTLW/EFLW is greater than 1,
wherein a ratio TTLT/EFLT is smaller than 1,
wherein the Telephoto lens unit has an optical axis, an optical diameter smaller than 5 mm and a F# smaller than 3.2 and includes, in order from an object plane to an image plane along the optical axis, a first lens element having positive optical power and two last lens elements, wherein one of the two last lens elements has an Abbe number greater than 50, and wherein the other of the two last lens elements has an Abbe number smaller than 30.
