PURPOSE: An iris device, a camera, and an electronic device are provided to reducing a space for a filter converting device and to reduce driving force required for a conversion of an optical filter. CONSTITUTION: An iris device comprises an iris member, a first rotating member, a second rotating member, a rotation transmitting member, two optical filters(26,27), a filter supporting member(28), a base member, and a filter converting member. The iris member forms an iris opening passing through incident lights. The second rotating member rotates according to a rotation angle and a rotation direction of the first rotating member and comprises an operation pin at a position spaced from a magnetism rotation central axis. The rotation transmitting member transmits torque to the second rotating member from the first rotating member and rotates the second rotating member at an angle larger than the first rotating member by the transmission of the torque. The filter supporting member supports two-dimensionally the two optical filters side by side and comprises a long hole interlocking with the operation pin. The base member supports the filter supporting member so that the filter supporting member freely moves to a first axial direction. The filter converting member converts an arrangement state of the optical filter with respect to an incident optical passage. |
