The world's oldest and most expensive camera

A Daguerréotype camera - one of the first commercially produced cameras - is set to go on sale with an estimated price of £600,000.That will make the wooden sliding-box 1839 camera, the oldest and most expensive in the world.It was built by Alphonse Giroux, the brother-in-law of Louis-Jacques-Mandé Daguerre and is even signed by Daguerre himself, the inventor of the first practicable photographic process. The rare camera has been in private ownership in northern Germany for generations and the present owner’s father gave it to him in the 1970s as a present when he became an optician. It features a black velvet interior and ground-glass screen… no there is no autofocus or face.
