The Nikon Slide Copying Attachment ES-1 is a simple slide duplicator attachment for use with the 55mm f3.5 Micro-Nikkor lens and PK-13 extension tube (sold separately). If youve got the right lens, this is about as simple a slide-duper setup as you can get: it just threads right in and holds the slide in place, with a diffuser panel to even out the light. For slides only, not negatives. Includes original box.
