New firmware has been released for the Nikon D7000, version 1.03. Be sure to update your camera, as it will fix several minor bugs including some settings and displays that have mysteriously changed on their own previously.
Update information on the Nikon site here:
The Nikon D5100 firmware has also been updated for the first time, v 1.01, with fixes including:
- An error recognizing some memory cards has been addressed.
- When Selective color from the retouch menu is performed on a picture taken with the image quality set to NEF (RAW)+JPEG and an image size of M or S, the edges of the image may not have changed color. This issue has been resolved.
- When Metering was set to Matrix metering, the exposure mode set to M (Manual), and the HDR exposure differential set to Auto, the exposure differential was fixed at a value equivalent to 2 EV. This has been changed to enable automatic adjustment of exposure differential so that it is appropriate for the scene.
