Abstract:
A wide angle photographic lens assembly comprises, in order from an object side to an image side, a first lens element with negative refractive power having a convex object-side surface and a concave image-side surface, a second lens element with positive refractive power having a concave object-side surface and a convex image-side surface, a third lens element, a fourth lens element with positive refractive power, a fifth lens element with negative refractive power, and a sixth lens element with positive refractive power. By adjusting the conditions among the above-mentioned lens elements, the wide angle photographic lens assembly can provide a wide-field of view and correct the aberration in order to obtain superior imaging quality.
