This attachment adapts the Polaroid Macro 5 SLR camera to photograph subjects at 5 times their original size without physical contact.
The attachment is a snap-on frame that clips to the front of the camera. The attachment redirects the ranging lights of the camera, causing them to converge at the point of optimal focus for a 5X photograph.
The attachment is useful in medical applications, such as ophthalmic, and in law enforcement for documenting fingerprints and handwriting.
