A lens system includes an operating unit for operating a lens apparatus, an operation-side communication unit performing bidirectional communication to/from the operating unit via a transmission line, and a lens-side communication unit performing bidirectional communication to/from the lens apparatus via a transmission line. The operation-side and lens-side communication units perform wireless communication to/from each other. The operation-side communication unit includes a command selecting unit selecting a command to be transmitted to the lens-side communication unit from commands input from the operating unit, and an answer interpolating unit generating an interpolated answer by interpolating answers with respect to commands that are not selected. The lens-side communication unit includes an answer selecting unit selecting an answer to be transmitted to the operation-side communication unit from answers input from the lens apparatus, and a command interpolating unit generating a command by interpolating commands received from the operation-side communication unit.
