With the probable(*) exception of pinhole cameras, movements are pretty much the main reason for moving beyond roll film. While I have used 5x4 as a hand-held without movements, that is not really where the benefits of large format accrue. I built a very basic 8x10 monorail to see if I wanted to take on that format. Since I already had a lens and could develop the film, all I needed was an investment in a couple of film holders to play. The charitable description would be 'crude yet functional'! It originally started as a pinhole box

* There are some cases where an offset pinhole is useful, but it is probably easier to build a box that way than make it adjustable.
