I recently purchased an ES-1 Nikon Slide Copying Adapter to digitize 35mm slides. The ES-1 is intended for a Nikon 55mm f/2.8 macro lens. Therefore, I plan to purchase a used Nikon Micro-Nikkor 55mm f/2.8 lens with 52mm filter threads. The ES-1 will attach directly to the lens. In order to achieve a 1:1 focus ratio, it is recommended that a PK-13 extension tube be fitted between the camera body & the lens. Assumingly, this combination will provide a 1:1 focus ratio without cropping the 35mm slide.
Since I am venturing into virgin territory, I would appreciate any input from those of you who are familiar with the ES-1.
Thank you kindly,
