Abstract

A camera body and an interchangeable lens removably mounted thereon are equipped with an automatic focusing arrangement. The interchangeable lens includes a signal means for generating a relation signal representing the relationship between the driving directions of a driven section and a focus adjusting section. The camera body includes a focus condition detecting circuit for generating a focusing signal indicating the direction for focusing, a driving section for driving the driven section and change-over means for reversing the relationship, between a direction indicated by the focusing signal and a driving direction of the driving section in response to the relation signal from the signal means.
