Nikon’s newly released flagship flash unit, the SB-910 AF Speedlight, is the successor to the SB-900 and features a wealth of new updates for additional convenience and control over your lighting setup.
The SB-910 has an improved graphic user interface and dedicated menu button for clear and efficient modification of settings as well as backlit buttons for use in low light. Its guide number of 111.5’ / 43m at ISO 100 provides sufficient illumination and supports Nikon’s iTTL metering for on camera or wireless flash control. Additionally, this flash unit can serve as a wireless commander for up to three separate groups of flashes, with an unlimited number of flashes per group. An improved thermal protection system keeps the flash working more consistently, utilizing thermal cut-out to slow recycle times instead of completely turning the flash off. The SC-29 TTL Off-Camera Shoe Cord provides full TTL convenience while allowing you to hand-hold the flash. The flash cord also incorporates an AF illuminator to greater facilitate low-light focusing. The SB-910 is powered by four AA batteries or for shortened recycle times you can utilize the SD-9 Battery Pack, which uses between four and eight AA batteries.
