Nikon has released updated firmware for its SB-900 Speedlight flash strobe on its support website.
The Nikon SB-900 was introduced in July 2008, and Nikon states that version 5.02 of firmware includes two changes as follows: "With uninterrupted shooting with the SB-900 set to i-TTL mode, images captured just before the flash ceased firing were sometimes overexposed. This issue has been resolved. By resolving this issue, metering precision has been further increased and the number of times the flash fires has also been increased. When the SB-900, set to TTL auto flash mode, is used with a camera supporting the Nikon Creative Lighting System (CLS), flash mode automatically changes to A mode according to camera communication status. That flash mode was previously maintained, but it has been modified so that TTL auto flash mode is restored once the SB-900 again recognizes the camera as a CLS-compatible camera."
The current firmware version of an SB-900 flash can be confirmed by turning the strobe on, and holding down the "OK" button for one second, then selecting the "VER."option in the custom settings menu. The update is available to both Windows and Mac OS customers, and can be applied using the D3, D300, D700 and D90 digital SLRs.
