ABSTRACT:
There is provided a behind stop wide angle lens system which comprises a positive lens L.sub.1 formed by joining a negative meniscus lens L.sub.11 whose convex surface faces an object and a positive meniscus lens L.sub.12 whose convex surface similarly faces the object, a biconcave negative lens L.sub.2, a biconvex positive lens L.sub.3 and an aperture stop S, disposed in this order from the side of the object. The behind stop wide angle camera achieves a wider angle of view and has an excellent imaging performance in spite of a simple structure and a compact size thereof.
