  • Publication number: 20180348599
    Abstract: An image capturing apparatus on which an accessory including a first mount is mountable includes a second mount. The second mount is configured to allow bayonet coupling to the first mount of the accessory. The second mount includes a plurality of terminals disposed in a circumferential direction, and a terminal holder configured to hold the plurality of terminals. Each of the plurality of terminals is electrically connectable to a terminal of the accessory. The terminal holder has a height level difference in a center-axis direction of the second mount. The plurality of terminals include a first terminal configured to be used to detect mounting of the accessory on the image capturing apparatus. The first terminal is disposed further in a mount direction of the accessory than the other terminals among the plurality of terminals on a first stage of the terminal holder.

  • Publication number: 20180352140
    Abstract: In a camera body, a VBAT terminal and PGND terminal are both disposed adjacent to a TYPE terminal. In a case where the voltage of the TYPE terminal is a voltage of a first voltage range that does not include the VBAT voltage and does not include the voltage of the PGND terminal, a camera control unit distinguishes the mounted lens apparatus to be a first lens apparatus. In a case where the voltage of the TYPE terminal is a voltage of a second voltage range that is a voltage range different from the first voltage range, does not include the VBAT voltage and does not include the voltage of the PGND terminal, the camera control unit distinguishes the mounted lens apparatus to be a second lens apparatus.

  • Publication number: 20180348604
    Abstract: An image capturing apparatus on which, and from which, an accessory is mountable and dismountable includes a plurality of terminals disposed in a circumferential direction of a mount, and a terminal holder. The terminal holder has a height level difference for holding the terminals at different positions in a center-axis direction of the mount. The terminals include a first terminal configured to be used to supply power for driving an internal component of the accessory, and a second terminal configured to indicate a ground level corresponding to the first terminal. The second terminal is disposed nearer in a mount direction of the accessory than the other terminals on a predetermined stage of the terminal holder, and is connected to a corresponding one of a plurality of terminals of the accessory first among the terminals when the accessory is mounted on the image capturing apparatus.

  • Publication number: 20180352122
    Abstract: A camera body includes a DCL terminal, a DLC terminal, and a LCLK terminal, that perform communication with a lens apparatus by a first voltage, or a second voltage that differs from the first voltage. The camera body also includes a DLC2 terminal that is only used when communication using the DCL terminal, DLC terminal, and LCLK terminal is performed by the first voltage. The DLC2 terminal is disposed adjacent to the LCLK terminal.

  • Publication number: 20180348608
    Abstract: There are provided a plurality of terminals disposed in a circumferential direction of a second mount of an image capturing apparatus. The plurality of terminals correspond to a plurality of terminals disposed in a circumferential direction of a first mount of an accessory. The plurality of terminals of the image capturing apparatus include a first terminal used to supply power for driving an internal component of the accessory, and a second terminal used to supply power for controlling communication with the accessory. The first and second terminals are disposed further in a mount direction of the accessory than the other terminals of the image capturing apparatus on a predetermined stage of the terminal holder. An inter-terminal pitch between the first and second terminals is wider than at least one pitch among inter-terminal pitches of the other terminals.

  • Publication number: 20180348605
    Abstract: There is provided an image capturing apparatus on which, and from which, an accessory is mountable and dismountable by relative rotation in a circumferential direction. The image capturing apparatus includes a plurality of terminals disposed in a circumferential direction of a mount and configured to be used in electrical connection, and a terminal holder. Each of the plurality of terminals is electrically connected to a corresponding terminal of the accessory. A first terminal of the terminals used in communication at a first voltage level and a second terminal of the terminals used in communication at a second voltage level lower than the first voltage level are disposed on the same stage of the terminal holder. The second terminal is a terminal connected to ground via a first resistor. The first terminal is disposed adjacent to the second terminal.

  • Patent number: 9001264
    Abstract: The present invention relates to a camera and an interchangeable lens capable of further improving the operational performance while supporting an old-type interchangeable lens using a communication method in the related art. The camera to which the interchangeable lens is detachably attached and which is capable of switching between a first communication mode and a second communication mode as a communication method between the camera and the lens includes a first terminal and a second terminal used to communicate with the lens. In the first communication mode, the camera outputs a clock signal through the first terminal and receives information about the lens through the second terminal on the basis of the clock signal. In the second communication mode, the camera receives information about the lens through the first terminal and the second terminal without outputting a clock signal through the first terminal.

  • Patent number: 8447180
    Abstract: An imaging apparatus includes an image sensor, a display unit configured to display an image acquired from the image sensor, and a control unit configured to perform a live view display of an image of an object on the display unit for a user to observe the object and to perform photographing after a self-timer setting time elapses from when a photographing start operation is performed, wherein the control unit compares, when performing the live view display, time required for charging a flash and the self-timer setting time, and if the self-timer setting time is longer than the time required for charging the flash, the control unit does not cause a charging operation of the flash to be performed before starting to count the self-timer setting time and causes the charging operation of the flash to be performed after starting to count the self-timer setting time.
