Sunpak's DF3000C Digital Flash provides plenty of affordable lighting power for your Canon camera along with E-TTL / E-TTL II metering. The DF3000C has a guide number of 92' at 100 ISO and a 85mm setting, and recycles in 0.5 to 7 seconds (depending on power setting and the condition of your batteries). It has TTL compatibility (except wireless TTL) and other professional features like auto focus assist for low light situations, a four-position manual zoom head, and a bounce head with a 90° range. The head also swivels 300°. An auto power off keeps your batteries in good shape. The DF3000C is powered by easily-found 4x alkaline or Ni-MH AA batteries (not included).
