SB-910 Speedlight

The Nikon SB-910 AF Speedlight is a powerful on-camera flash unit featuring a guide number of 111.5' at ISO 100 and 35mm, with full compatibility with Nikon's i-TTL system for both FX- and DX-format cameras. The flash head offers complete bounce and swivel functionality, tilting from -7° to 90° and rotating 180° in either direction, while an auto zoom head adjusts coverage from 17-200mm on FX-format cameras and 12-200mm on DX-format cameras, with a built-in wide-angle diffusion panel extending coverage down to 12mm or 8mm respectively.

The SB-910 operates as both a standalone flash and a Commander unit for wireless TTL control of up to three off-camera flash groups across four channels. It provides multiple synchronization modes including slow sync, Auto FP high-speed sync, first and second curtain sync, and stroboscopic repeating flash from 1-100 Hz. The unit runs on four AA batteries with recycle times between 2.3 and 4.5 seconds depending on battery type, and includes accessories such as a bounce card, diffusion dome, color correction filters, stand, and carrying case.
