Product description

Manufacturer description: The newest addition to the Sigma line of flashes is the most powerful one yet, now offering a Guide number of 61 which translates into 61/m (200/ft) and designed to work with the latest TTL auto exposure systems of all the most popular digital and film SLR cameras. It features TTL automatic flash exposure control for easy operation. The auto zoom 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 the angle of 17mm. For bounce flash, the flashgun head can be tilted up and to the right by 90 degrees, or to the left 180 degrees. It can also be tilted down by 7 degrees allowing ease of use for close-up photography. In addition to automatic mode, the flashgun also features a manual flash mode, making it possible to set the flash power to full or 1/16. When the flashgun is fully charged, a confirmation “ready” light will be emitted and the flash exposure level can be checked through the camera’s viewfinder. Also includes Auto Power-Off function to help save battery power.
