A lens assembly in a camera includes a first meniscus lens (10) and a second meniscus lens (11) respectively having a first radius of curvature (A,A') and a second radius of curvature (B,B') larger than that of the first radius of curvature A,A'), a concave lens (12) having a first radius of curvature (C) and a second radius of curvature (C') smaller than the first radius of curvature (C), and a convex lens (13) having two opposite sides with a radius of curvature so that after a distance between the lens to the object is determined, a clear image is presented.
