Abstract
Apparatus for delivering distance information of a camera includes counter means which counts a relative distance corresponding to a movement of a taking lens. The counter means is reset when the taking lens reaches a reference position located at infinity. Using stored data (absolute distance factors) which is specific to a taking lens and the count in the counter means, an absolute distance is derived.
