The Open Camera Controller uses your camera’s remote shutter release cable port. It has been tested with the Canon 30D, 40D, 50D, 5D, & 5D Mark II, Sigma DSLR’s, the Casio EX-FX1, and the Olympus E-P1 also work with a few quirks and limitations.
If you haven’t bought a Promote Control because you own a Sigma or Olympus (those cameas are not supported with the Promote Control), don’t despair… help has arrived. Surf on over to HDR Labs to check out the Open Camera Control
