The first lens element is a meniscus lens having a weak refractive power and concave toward the object side, the second lens element is a lens having a positive refractive power and the third lens element is a lens having a negative refractive power. A stop or an assumed stop is disposed close to the object side end of the lens system or on the object side of the same formula .nu..sub.3 .ltoreq.40 is satisfied wherein .nu..sub.3 represents the Abbe's number of the third lens element.
