Nikon released its SB-600 Speedlight Flash in 2003. This flash is designed for use with digital SLR cameras and mounts on most Nikon DSLRs. The SB-600 originally retailed for $249, but is available for $219 (as of December, 2010).
Battery Issues
Most of the known issues with the SB-600 Speedlight are a result of low battery power, which can be responsible for the flash not powering on, the ready light not activating or a noise emanating from the flash head.
Zoom-Head Problems
Nikon lists troubleshooting steps for a couple of different problems with the zoom head in the SB-600 Speedlight manual. Most notably, a "- -" error message will flash on the zoom head position indicator, which indicates that an adjustment error has occurred. To resolve this issue, turn off the flash pack and the camera, remove the flash from the hot shoe, then reattach it and turn the camera and flash back on.
Reviews
In addition to the minor issues that Nikon identifies in its user guide, reviewers have pinpointed some shortcomings of the SB-600 speedlight. The product is reviewed positively overall, but some of the listed drawbacks include a confusing manual, less-than-average battery life and that flash doesn't have external connections for a battery and cannot be mounted separate from the camera. Some users have also complained that the flash isn't fast enough to work with high-speed lenses.
