12 page PDF sales document from Franke und Heidecke 2008
This is a useful introduction to the X-Act 2 technical camera, the lens contol S, and all the available parts from the lenses and bellows, to the film back carriers, etc. When I was getting started with the X-Act 2 this document was really helpful in identifying what i needed. You can get sliding back adapters for digital backs including the AFi and Credo series and several others. Also available are rear adapter plates to fit DSLR cameras.
