Sigma EF-500 DG Super

Check availablity: eBay.

This flash gives slightly more bang for the buck than the manufacturer's own flash with roughly the same power output. However, the build is less solid, some users report erratic exposure control, and the user interface is less intuitive.

Note that there also exists a version designated “500 Super” (i.e. no “DG” as part of its model designation). This version is not compatible with digital cameras.

Models that have “DG” as part of the model designation is compatible with Canon DSLRs manufactured before 2008, but is not compatible with the Canon EOS 50D and later models. See this notice to customers using Sigma's EO-ETTL II type flashguns for details.

Sigma is a family owned manufacturer of photographic equipment founded in 1961 in Japan. The company's main business is to manufacture third party lenses. However they also produce third party flash units and, since 2002, their own line of DSLR and compact cameras. Sigma's digital cameras use a special sensor, developed by Foveon, that records full color information for every pixel. In late 2008 Sigma acquired Foveon.
