a page about the camera and the manuals for it are available as pdf's here.
I also use 5x7, 4x5, and 2x3 reducing backs when necessary.

when I want to use a 4x5 with out the size of the 8x10, I use this. it's particularly useful for polaroids.
for medium format I like the ease of a twin lens reflex.
in 35mm this camera has never failed me.
for my scanning needs, I use a howtek drum scanner.
