The first menu-driven camera I ever confronted was a film camera, a used F6 that I picked up. The Nikon manual is pretty much useless in telling you what the menu functions are, and how to set up a camera to do things your way. It was easier learning to program an Excel spreadsheet. Fortunately, there is a big market in publications that fill in a lot of the blanks (I like Thom Hogan's books, electric and otherwise). When I picked up a user D7000, the transition wasn't too difficult,
My primary digital camera, a Monochrom, has a relatively modest menu system, and a lot of the menu items (once you learn what they do, and the Leica manual isn't overly helpful in that regard) can be safely ignored. The user profile feature is good for people (like me) who are too cheap to have their "old" Leica lenses given the 6-bit coding treatment. Instead of hunting through the lens profile menu when switching lenses, I just set up user profiles for each lens, and select that instead.
