Nikon debuted a new clip-on type electronic flash, the successor to the current model SB 900- the SB910.
The SB910 features improved operability with a new menu button and a guide on the monitor. Distribution of light can be selected from standard light distribution, center-priority light distribution or even light distribution. Guide number of the flash is 43 (ISO100) for 35mm lens on FX format (full 35mm size).
The head turns 90 degrees upward, 7 degrees downward and 180 degrees each, left and right. Four AA-type batteries power the flash unit.
