To provide an interchangeable lens capable of performing favorable optical correction even when being mounted in an inverted state, and an imaging device using the same.
Electric contacts 102 and 104 are provided at an interchangeable lens 100. The interchangeable lens 100 is configured in such a manner that it can be mounted in an inverted state in which the electric contact 104 is facing an imaging device 200 as well as in a normal state in which the electric contact 102 is facing the imaging device 200. Also, in a lens characteristic information storage unit 114 of the interchangeable lens 100, both lens characteristic information for the normal state and lens characteristic information for the inverted state are stored. A lens control unit 116 transmits the lens characteristic information for the normal state to the imaging device 200 when the interchangeable lens 100 is mounted in the normal state, and transmits the lens characteristic information for the inverted state to the imaging device 200 when the interchangeable lens 100 is mounted in the inverted state.
