Abstract
A camera system comprising a camera body and an interchangeable lens assembly adapted to be coupled to the camera body. The interchangeable lens assembly has no manipulatable aperture adjusting ring, but has an aperture mechanism and a read-only memory both built therein.

The camera body communicates with and power the lens assembly through a set of terminals connectable with associated terminals provided in the lens assembly. The terminals in each of the camera body and lens assembly are arranged in a generally arcuate row with the data transmitting terminal located at one extremity of the arcuate row on the leading side with respect to the direction of turn of the lens assembly which is effected when the lens assembly is to be completely coupled to the camera body.
