1. A dual-aperture camera, comprising:
a Wide camera having a Wide lens with a field of view FOVW and having a total track length TTLW and an effective focal length EFLW, and a Telephoto camera comprising a Telephoto lens 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 has an optical axis 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, wherein the other of the two last lens elements has an Abbe number smaller than 30, and wherein a height H of the dual-aperture camera measured along the optical axis is in the range of 4 mm-12 mm.
