Changes from “C” Firmware Version 2.00 to 2.01:
• Changed the default values for the following settings displayed when connecting wirelessly:
- Encryption keys
- The password displayed after the camera's default settings are restored
• Fixed the following issues:
- Green color casting occurred with some pictures taken.
- The date and time set in camera sometimes would not be correctly applied.
- Using [Picture review] to view an image in a “tall” (portrait) orientation and zooming in the image prevented the display from being scrolled to the intended direction with multi selector or sub-selector.
- After a firmware update, the eye sensor sometimes would not function and the viewfinder would not turn on.
- The “i” menu would sometimes remain in the viewfinder when it was looked through after the shutter-release button was pressed halfway to exit the “i” menu viewed in the monitor.
IPTC Presets
Performing this update from a “C” firmware version 1.01 or earlier will delete IPTC presets in the camera. This is an intended consequence of improvements to IPTC presets. Users who intend to continue using existing presets will need to copy them to a memory card using [IPTC] > [Load/save] > [Primary slot]/[Secondary slot] > [Copy to card] in the [SETUP MENU] before performing the update. The saved presets can be loaded from the memory card using [IPTC] > [Load/save] > [Primary slot]/[Secondary slot] > [Copy to camera] once the update is complete.
Note that IPTC presets cannot be loaded if menu settings were saved to a memory card using [Save/load menu settings] > [Save menu settings] in a camera with a “C” firmware version 1.01 or earlier and loaded to the camera using [Save/load menu settings] > [Load menu settings] after performing this update. Be sure to copy and load the IPTC presets individually via the method described above.
