1. A folded lens assembly for a folded camera, consisting of: N=5 lens elements that include, in order for an object side to an image side, a first lens element L1 with a first lens element surface clear aperture CA(S1), a second lens element L2 with a second lens element surface clear aperture CA(S3), and a fifth lens element with negative refractive power, wherein CA(S1)/CA(S3)>1.2, and wherein the lens assembly has a ratio between an image sensor diagonal length SDL and a clear aperture of a last lens element surface CA(S2N), SDL/CA(S2N)>1.5, wherein the first lens element has positive refractive power and the second lens element has negative refractive power, and wherein the N lens elements further include a third lens element with positive refractive power and a fourth lens element with negative refractive power.
