My issue with the Cambo as a field camera it that it is hard to make compact. The usual approach is to disconnect the bellows and swing both standards 90 degrees. This makes the entire package large but flat. Problem is I don't really have any bags that accomodate a camera like that. If that works for you, though, its a pretty nice, and rigid camera that sells for very cheap. it will also probably have issues with lenses shorter than 75mm because the standards can get close enough to focus infinity. That can be worked around by swinging the rear standard 180 degrees but then I believe the film holder needs to be inserted from the top because the rise/fall rails are in the way.
(FYI, I have no experience with the Cambo 4x5, but I do own a Cambo 2x3 that has the above issues, and most of the parts are the same. Not going wider than 75mm on a 2x3 camera is more of an issue.)
