The DM680EX TTL Flash for Canon from Digitalmate is a dedicated flash for use with Canon DSLR or point-and-shoot cameras. The SB680EX features a guide number of 278′ at ISO 100 and an adjustable tilt head with six positions: -7 to 90°. The -7° downward tilt allows you to fully illuminate your subject when shooting close-up. You can also twist it to the left up to 90° and to the right up to 180°. It covers a 24-180mm range (in 35mm full frame format) and extends to 18-180mm with the diffuser panel in place. In auto mode the zoom range is stepless, it does not set at 24mm, 35mm, etc, but matches the exact focal length of the zoom lens for optimal lighting. The flash supports rear curtain synchronization for shooting at slower shutter speeds. The DM680EX is equipped with wireless (optical) manual slave function.
The DM680EX has an auto-focus assist for low-light photography, and an automatic power-saving function that turns the flash off when it’s inactive. It is powered by four AA batteries (not included), with a flash duration between 1/800 and 1/20,000 of a second. A convenient HV port allows you to connect the flash to an external power source for extended usage and faster recycling. The included stand allows you to set the flash up on a flat surface or to attach it to a tripod head, light stand, or clamp that has a standard 1/4″-20 mount.
