Nikon has made available a firmware update for its SB-900 flashgun.
Version 5.02, which can be downloaded now, fixes two glitches.
Explains Nikon: ‘With uninterrupted shooting with the SB-900 set to i-TTL mode, images captured just before the flash ceased firing were sometimes slightly overexposed. This issue has now been resolved.’ It adds that it has also increased the flashgun’s metering precision as well as the number of times the flash fires.
Nikon continues: ‘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 now been modified so that TTL auto flash mode is restored once the SB-900 again recognises the camera as a CLS-compatible camera.’
Both the D3 and D300 cameras can be used to upgrade SB-900 firmware.
