The camera is very well built, but odd. A knob on the top left focuses by moving the focal plane. A little clunky to use, but it does take good shots.
That feature must surely make it possible to produce lenses for less as no focusing mechanism is required for each lens. One would, I imagine, quickly grow accustomed to that feature. The beautiful Vitessa L has a similar feature. I think it simplifies focusing and aids in steadying the camera as both hands can be kept on the camera's body which, except for long, heavy lenses is preferable.
Manual cameras? Surely only the old-old cameras were truly manual. You know, those that the photographer took the lens cap off, counted to five and put it back on again. Then he, or she, removed the film plate and replaced it with another (in the darkroom of course). Everything else is automation of some sort.
