Wetpixel member and contributor David Haas has submitted a review of the Ikelite 300D housing based on his experience shooting macro and wide angle in the Galapagos Islands. According to Dave:
The week of October 11-18, 2004 found me aboard the vessel Deep Blue in the Galapagos Islands . Ikelite had sent me a SLR-DC housing for the Canon Digital Rebel with their new eTTL circuit board to test. As of this writing the PC board has a new revision enabling it to work with Ikelite's DS125 and DS50 strobes plus most brand TTL strobes.
