The Sunpak RD2000 Digital Shoe Mount Flash is a compact and ultra-low profile flash, which fully supports TTL flash operation with digital SLR cameras. This version is dedicated to the Canon digital SLR camera line, and fully supports Canon's E-TTL II flash operating system.
The flash is only powered by two AA batteries, which keeps it compact and lightweight. At the same time, it provides up to 200 flashes at full power. Following a low profile design, this flash barely extends 2" above the camera. It can also be used fully vertical, for ceiling bounced shots. Its light output can be adjusted with a range of +/-1 EV in 0.5 increments (5 settings).
When you are done shooting the shoe can be rotated into the body making it very convenient to carry around. The RD2000 is a handy flash that complements the compact design of digital SLR cameras.
Note:This flash is compatible with the 5D II. Some older units may require a firmware update. Contact Sunpak for free servicing.
