Title
(JA) カメラシステム、カメラ、交換レンズ、及び、カメラシステムの互換性判定方法
Abstract
(JA)

簡単かつ迅速にカメラと交換レンズとの間の互換性を判定できるカメラシステム、カメラ、交換レンズ、及び、カメラシステムの互換性判定方法を提供する。カメラ(10)に備えられた第11の端子(CC11)及び交換レンズ(100)に備えられた第11の端子(LC11)をオープンドレイン出力が可能な端子で構成する。カメラ側の第11の端子(CC11)は、カメラ(10)が、特定の機能に対応している場合、第1極性に設定され、対応していない場合、第2極性に設定される。交換レンズ側の第11の端子(LC11)は、交換レンズ(100)が、特定の機能に対応している場合、第1極性に設定され、対応していない場合、第2極性に設定される。互いに接続されたカメラ側の第11の端子(CC11)及び交換レンズ側の第11の端子(LC11)は、互いが第1極性の場合にのみ第1極性となる。したがって、カメラ側の第11の端子(CC11)の極性及び交換レンズ側の第11の端子(LC11)の極性を検出すれば、カメラ(10)及び交換レンズ(100)の双方で互換性の有無を判定できる。
