Occasionally, once or twice a year, you should check Nikon's site to see if your camera has a firmware update.
My camera shipped with firmware version 1.00 and has now been upgraded to
D5100 firmware: A: 1.0.1 / B:1.01 released 2011.11.10
(There are A and B and L firmware versions. This upgrade updates the A and B.)
From Nikon's site: These issues were resolved:
- An error where the card may not have been recognized when some memory cards were used 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
There may be other changes to insignificant to document and it is always advisable to apply the latest.
Applying a firmware update to the camera is easy. Roughly, download the firmware to a computer, expand the compressed zip file and copy the resulting ".bin" to the root of an SD Memory card. Insert the card into the camera and open the camera's Firmware Version menu. Follow Nikon's instructions and power-cautions carefully. Full details can be found at this link.
