Featuring an LED video light and a compact design, the SB-500 AF Speedlight from Nikon provides users with a portable unit for use specifically with Nikon's i-TTL metering system. The flash has good power with a guide number of 79' at ISO 100 and while no direct manual adjustments are available the output can be tuned via the camera's flash exposure compensation settings. The unit offers wide coverage for a 24mm lens with FX-format full-frame cameras and the 100 lux LED light has quarter, half or full power output levels, which is beneficial for both video and close up still photography.
