Downloads : Firmware Update

Thank you for using GR IIIx digital camera.
RICOH IMAGING COMPANY, LTD. wishes to announce the release of Firmware Update Software Version 1.60 for GR IIIx.
Firmware in this document is the software that runs inside digital cameras.

Changes to V1.60

<Added the following enhanced features>

• A new exposure mode [GF-2 Flash Mode] has been added, which automatically adjusts the camera's exposure settings when the external flash GF-2 is attached and used for flash photography.
  After updating to firmware version 1.60 or later, the [GF-2 Flash Mode] will be added to the camera's menu.
  
  

  When the [GF-2 Flash Mode] is enabled in the settings menu, the camera automatically switches to [GF-2 Flash Mode] when the mode dial is set to P, Av, Tv, or M.
  

  When [GF-2 Flash Mode] is selected, the exposure mode indicator in the lower-left corner of the LCD screen will display [GF-2].
  

  [GF-2 Flash Mode] automatically calculates the appropriate exposure value before shooting, based on the subject distance measured by autofocus or the distance set manually via manual focus, and adjusts the exposure accordingly to ensure proper exposure during flash photography.
  When the ISO sensitivity is set to a fixed value, the camera's ability to automatically adjust the exposure is limited, which may result in unintended overexposed or underexposed images.
  * When attaching the external flash GF-2 to the camera, make sure that both the camera and the GF-2 are turned off. Remove the hot shoe cover, then insert the GF-2 straight into the hot shoe mount all the way to the back.
  **If the external flash GF-2 is properly attached, the flash mode icon () will not be displayed on the camera's rear LCD screen. If the icon () is displayed, please note that the GF-2 is not fully inserted into the innermost part of the hot shoe.
  * Please note that the external flash GF-2 does not have a locking mechanism to prevent it from coming loose.
  * When removing the external flash GF-2 from the camera, make sure that both the camera and the GF-2 are turned off before detaching it.
  *[GF-2 Flash Mode] is an exposure mode that is only available when shooting still images. It cannot be selected during video recording.
  *[GF-2 Flash Mode] is an exposure mode that is only available when the external flash GF-2 is attached.
  When using the PENTAX AF540FGZ, AF540FGZ II, AF360FGZ, AF360FGZ II, AF201FG, or AF180FG, P-TTL auto flash is available for shooting.
  *In [GF-2 Flash Mode] the camera waits for the flash to complete charging before each shot. As a result, the shooting interval during continuous or bracket shooting will be longer than usual, approximately two seconds between shots.
  *[GF-2 Flash Mode] remains enabled after the camera is powered off and will be active when it is turned on again.
  *The camera cannot detect whether the external flash GF-2 is turned off or not attached. Therefore, if the flash does not fire while 'GF-2 Flash Mode' is enabled, the camera will still automatically adjust the exposure settings assuming the flash will fire, which may result in incorrect exposure. Please be aware of this.

• [GF-2 Flash Mode] can be assigned to the ADJ mode or Fn button from the custom settings menu.
  *From the Custom Settings menu – [2] Button Customization – ADJ Mode Settings, you can assign [GF-2 Flash Mode] to one of the settings from 1 to 5.
  *From the Custom Settings menu – [2] Button Customization – Fn Button Settings, you can assign [GF-2 Flash Mode'] to the Fn button.
  *[GF-2 Flash Mode] cannot be used in combination with Snap Distance Priority mode.
