To provide a shift-tilt lens having a large image circle by composing this lens of a first lens group composed of four lenses and having a positive refractive power as a whole and a second lens group composed of three lenses, having a positive refractive power as a whole and interposing a diaphragm.

A first lens group GR1, composed of a lens L1 having a positive refractive power, a convex meniscus lens L2 and convex meniscus lenses L3, L4 and having a positive refractive power as a whole, is provided while all convex surfaces of these lenses confront the object side. A second lens group GR2, interposing a diaphragm R9 between the first and second groups, composed of a lens L5, whose concave surface confronts the object side, being joined to a lens L6 and having a negative refractive power and lenses L6, L7, whose convex surfaces confront the side of image plane, having positive refractive powers, is provided. By this constitution, a large image circle is obtained compared with a lens having a similar focal distance in an interchangeable lens system.
