This is my setup for copying film/slides, and to also digitize them. Pentax DSLR, or any other brand DSLR or SLR. Bellows with slide attachment holder and marco lens. I can also reverse the lens for a flat field effect if I need to crop more than 1:1. I also have a Plustek 7600 film scanner, and this Pentax setup matches or beats the Plustek, plus it is much faster.
