Optical lens assembly, photographic unit, and electronics.

Abstract

The photographic optical lens assembly comprises seven lens elements in order from object side to image side: the first lens element, the second lens element, the third lens element, the fourth lens element, the fifth lens element, the sixth lens element, and the seventh lens element. The first lens element has positive refractive power and its object-side surface is convex in its inverting region. The second lens element has negative refractive power. The third lens element has a convex object-side surface in its inverting region. The sixth lens element has a convex object-side surface in its inverting region and a concave image-side surface in its inverting region. The sixth lens element has at least one inflection point. The seventh lens element has negative refractive power and its object-side surface is concave in its inverting region. Furthermore, the invention relates to a photographic apparatus comprising this lens assembly and an electronic device containing this photographic apparatus.
