<p><P>PROBLEM TO BE SOLVED: To provide a conversion adapter apparatus, by which it is possible to attach an interchangeable lens to a camera body having a different flange back, and which improves the layout of a communication contact point on a camera side and a communication contact on a lens side, and the layout of an electrical conduction member that performs electrical conduction of the communication contact points. <P>SOLUTION: A conversion adapter 30, which connects a camera body 10 and an interchangeable lens 20, includes: a camera body side attaching part 31 provided so as to be mounted on the camera body 10; and a lens side attaching part 33 provided so as to be mounted on the interchangeable lens 20. The conversion adapter 30 includes: a camera body side communication contact-point group 32 in contact with the communication contact-point group of the camera body 10; a lens side communication contact-point group 34 in contact with the communication contact-point group of the interchangeable lens 20; and the conducting member 301 which electrically connects the camera body side communication contact-point group 32 and the lens side communication contact-point group 34. A position of the camera body side communication contact-point group 32 around a camera optical axis and a position of the lens side communication contact-point group 34 around the camera optical axis are different from each other. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
