<p><P>PROBLEM TO BE SOLVED: To provide a lens system which is excellent in responsiveness even when any one of an analog demand and a digital demand is used as the commanding apparatus and performs radio communication between a lens apparatus and the commanding apparatus. <P>SOLUTION: The lens system includes: a lens apparatus including a member whose position or state varies continuously; and a commanding apparatus outputting a command signal to the member, wherein the lens apparatus includes a first communication unit performing radio communication through a master/slave communication system and a first set unit setting the first communication unit to a slave mode when the lens apparatus is initialized, and is configured to send to the commanding apparatus an answer on the member whose position or state varies continuously. The commanding apparatus includes: a second communication unit performing radio communication through the master/slave system and communicates with the first communication unit; and a second set unit setting the second communication unit to a master mode when the commanding apparatus is initialized. The lens apparatus includes a reduction unit deleting a part of a response signal sent from the first to second communication unit. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
