At DEMA 2004 here in Houston, Mark Rupert from Inon America took a few minutes to explain the functions of their new D-2000 Strobe. This is an optically-triggered only strobe, meaning there is no place to connect an electronic sync cord. It is specifically targetted at the underwater consumer camera photographer using a Canon, Olympus, or Nikon OEM housing, and wanting automatic flash exposure control. Inon Japan leant Wetpixel some equipment to review and test, as there is a lot of interest in the D-2000 and many questions about how well it works.
