Patent ID: 6927927

Claim:
A two-lens-element taking lens system for forming an image on a solid-state image sensor, comprising, from an object side: an aperture stop; a positive lens element; and a meniscus lens element convex to an image side, wherein the following conditions are fulfilled: 0.4 <D/f <1.9 −9<( R 3 + R 4 )/ R 3 − R 4 )<−2 and where f represents a focal length of the taking lens system as a whole; D represents an axial thickness from an object-side surface of the positive lens element to an image-side surface of the meniscus lens element; R 3 represents the radius of curvature of the object-side surface of the meniscus lens element; and R 4 represents the radius of curvature of the image-side surface of the meniscus lens elment.
