Nikon SB-910 Flash - Nikon's top-of-the-line SB-910 flash recharges faster than the Nikon SB-900, automatically detects zoom from 17mm to 200mm, and has multiple lighting patterns. The Nikon SB-910 i-TTL flash includes Nikon's Creative Lighting System and is compatible with Nikon FX and DX format SLR cameras. The flash has 3 lighting patterns: center weighted, flat and standard. When shooting in center-weighted mode, the lighting is concentrated in the center of the frame, this mode is useful when using a telephoto lens. Flat Mode provides uniform light diffusion throughout the frame and is ideal for group shots. Standard mode provides a standard balance of power and light distribution. 17-200mm auto zoom range provides coverage up to 14mm lenses when using the built-in diffuser or Speedlight dome. In addition, Nikon SB-910 flash now automatically detects camera sensor format (FX or DX). Flash can be recharged in 2.3 seconds in 2.3 seconds with LR6 NiMH batteries (at full power). If a filter is attached to the flash, the flash will automatically adjust the color temperature settings. Of course, the flash, like other Nikon flashes, can be manually adjusted.
