Nikon PS-4 Rail System
This unit can accommodate mounted slides and unmounted film. It has “arms” to support film strips, which makes it an excellent choice for scanning film strips and rolls. It also has the wider slot for mounted slides which allows for a the scanning of thicker custom mounted slides.
These units are modified in a couple ways: I removed the diffusion glass so that it can produce even, full frame illumination against a light table or other diffuse light source. Additionally, I’ve filed out the corners of the negative stage so that you get a nice black border on negative scans. And finally, I’ve cut some slots in the film support arms to better support strip film as shown in this photo.
Here’s a sample image showing the black border effect. This is not added in Photoshop - it’s actually part of the scan. Note that each device will produce a slightly different black border.
This version is suitable for use with a full frame camera and 60mm lens (or shorter), or an APS-C camera with a 40mm lens (or shorter).
If you wish to use a longer macro lens, purchase the extended rail upgrade ($25).
