Leitz Correfot Brochure

Very rare brochure of the Leitz Correfot, 3 languages (German/English/French) version, in mint condition, Leitz was the first brand in the world to develop an auto-focus prototype in 1976, adapted to the Leicaflex SL2 and presented to the Photokina. A secondary mirror deviated a part of the rays to a mobile pattern (mechanic system!) for an electronic evaluation of the MAP. Correfot means "maximal 'correlation' between two elementary light rays passing by the extreme edges of the ward of the lens and stemming of the same point of the subject, the Correfot never went into production.
