Stumbled across one of these FotodioX Pro Canon EOS Large Format 4 x 5 Adapter 4X5-EOS-P B&H and found it interesting. This one was for Canon, but they make them for all brands. Supposedly allows you to mount your DSLR to a 4x5 back. By moving the plate up/down/side to side, you can capture individual shots which you then stitch together post. Anyone used one of these, and comments on how well they work???
