Heretofore multi-image photographic printers capable of making packages of different sized prints up to 11x14 inches, have had to incorporate a separate and complete set of objective lens arrays for each negative size to be printed. This discloses a multi-image printer which provides a large number of different sized negative apertures using only one or two sets of primary objective lens arrays in conjunction with multiple secondary optical components, these primary objectives and secondary components are each designed with a residual of aberrations of opposite nature, so that in combination these act to mutually correct each other.
