A lens apparatus can be easily set even in cases where the lens body and demands are distant from each other upon shooting without a decrease in the reliability. A lens body 20 mounted on a camera body 10 is provided with command signal converting unit, time-series position signal converting unit, wireless communication unit, communication condition monitoring unit and communication process switch unit. A signal converting unit 90 to which a zoom demand 70 and a focus demand 80 are connected is provided with time-series command signal converting unit, position signal converting unit and wireless communication unit. The lens body 20 and the signal converting unit 90 are configured to wirelessly communicate with each other to eliminate the use of connection cables thereby improving operationality while enabling highly reliable wireless communication.
