There are hardly any modern-day P&S cameras with manual controls. That sort of goes against the idea of a point and shoot.

The Rollei AFM 35/Fuji Klasse has aperture priority or program autoexposure. Same goes for the Contax TVS.

And generally, a point and shoot isn't made to be serviced -- just replaced. And most point and shoots have very slow lenses.

Perhaps, what you want is a compact 35mm camera from the 1970s or earlier. The Rollei 35 has all-manual exposure but is scale focus (guess).

The Olympus 35 RC has trap-needle autoexposure or full manual exposure.
