The Sunpak RD2000 is an ultra compact & portable hotshoe flashgun with full E-TTL-II metering capability when used with Canon DSLR's. The head can be tilted through 90 degrees vertically for bounce flash functionality while the hotshoe rotates away into the body when not in use. A built in wide angle diffuser gives coverage to 24mm (in 35mm focal lengths). Powered by two AA batteries the flash recycles to full power in approx 5 seconds.
