<p>A photographic lens disposed between an object and an image formation surface, a diaphragm being provided between the photographic lens and the image formation surface, the photographic lens being a positive meniscus lens provided with the convex surface on the object side, the photographic lens projecting an image of the object on the image formation surface. A curved lens surface at least on the image formation surface side is formed in accordance with a function by which an aspheric deformation amount in a position on the lens surface is negatively increased the further the position is from the optical axis of the meniscus lens. <IMAGE></p> |
