Among Nikon's largest on-camera flash units, the SB-910 AF Speedlight brings with it excellent power, a plethora of features, and a Commander mode for wireless TTL control. The flash is compatible with the i-TTL system for automatic metering with both FX- and DX-format cameras and is a part of the Nikon Creative Lighting System for complete control over your lighting setup. Also, it features a guide number of 111.5' at ISO 100 and 35mm for illuminating your subjects. Additionally, the auto zoom head has a coverage range of 17-200mm with FX-format cameras which can be extended down to 12mm with the use of the built-in wide-angle diffusion panel.
Complete bounce and swivel functionality is available for working in a variety of shooting situations. This allows users to tilt down to -7° and up to 90° as well as rotate left or right 180° for complete 360° coverage. Also, the SB-910 has three different illumination patterns, standard, even, and center-weighted, which help shape the light output for your specific needs. For wireless master TTL functionality, the speedlight utilizes a Commander Mode. In this mode users can access Advanced Wireless Lighting settings for controlling multiple off-camera flashes that can be set up in 3 groups (A, B, C) and one of 4 channels.
Many other abilities are packed into this unit, including a stroboscopic repeating flash mode that can be set from 1-100 Hz. The SB-910 also has slow, Auto FP high-speed, first, and second curtain sync modes for achieving the desired creative look in your image. There are even red-eye reduction and red-eye reduction slow sync settings available. The flash itself is mounted to the camera or stand with a locking hot shoe and is powered by 4 AA batteries. Depending on the type of battery used and the power setting, users can expect a recycle time of 2.3-4.5 seconds. The SB-910 can also work as the master unit in SU-4 type wireless multiple flash-unit photography.
