ABSTRACT OF THE DISCLOSURE An apparatus for viewing an original and for projecting an image thereof onto a moving imaging surface and a reproducing machine employing the apparatus. The apparatus includes a lens arranged along an optical path. The projected image magnification may be changed by translating the lens in a plane of motion between first and second positions. Apparatus are provided for tilting the lens with respect to the plan of motion to a different extent at the first position than at the second position to thereby reduce the occurrence of vignetting in the optical system.
