Variable magnification slide copy camera

A copy camera operative in at least two different magnification modes for selectively varying the size of an object projected onto a film unit, said copy camera comprising:

• a support member;
• a projection lens, having a given focal length, mounted at a fixed location on said support member;
• means for supporting a film unit alternatively at either of first and second film planes spaced at different predetermined fixed image distances from said lens for exposure to an image provided thereby;
• means for supporting an object alternatively at either of first and second object planes spaced at different predetermined fixed object distances from said lens, said different image and object distances being selected so that in one magnification mode an image of an object located at said first object plane is focused by said lens at said first film plane and is of a size predetermined by a first magnification factor and in another magnification mode an image of an object located at said second object plane is focused at said second film plane and is of a size predetermined by a second magnification factor that is different than said first magnification factor;
• and
• exposure control means operable for controlling transmission of image forming light rays from an object at either of said first and second object planes to a corresponding one of said first and second film planes to effect exposure of a film unit thereat.
