Sigma EF-610 DG Super Electronic Flash for Canon SLR Cameras

The autozoom function automatically sets the optimum illumination angle in accordance with the lens focal length in a range from 24mm to 105mm. When the built-in Wide Panel is used, the flash can cover an angle of 17mm. For bounce flash, the flashgun head can be tilted up by 90 degrees, to the left by 180 degrees, or to the right by 90 degrees. It can also be tilted down by 7 degrees allowing ease of use for close-up photography. The Auto Power-Off function automatically shuts off the LCD panel to help save battery power. When the flashgun is fully charged, a confirmation ready light will be emitted.
