Abstract
Digital cameras, optical lens modules for such digital cameras and methods for assembling lens elements in such lens modules. In various embodiments, the digital cameras comprise an optical lens module including N≥3 lens elements Li, each lens element comprising a respective front surface S2i-1 and a respective rear surface S2i. In various embodiments the first lens element toward the object side, L1 and its respective front surfaces S1 have optical and/or mechanical properties, such as a clear aperture, a clear height and a mechanical height that are larger than respective properties of following lens elements and surfaces. This is done to achieve a camera with large aperture stop, given a lens and/or camera height.
