Abstract: A retro-focus type wide angle lens has in succession from an object side a first negative meniscus lens having a convex surface facing the object side, a second positive lens, a third biconvex lens, a fourth negative doublet consisting of a biconvex lens and a biconcave lens, a fifth positive lens, and a sixth positive lens. Although this retro-focus type wide angle lens is formed of six lens groups and seven lens components, its field angle or angle of view is about 66.degree., its aperture ratio is 1:1.6, its total length is very short, the aperture of its first divergent lens group is very small and its various aberrations are satisfactorily compensated for.
