Very exciting news for Canon shooters: We just heard from Blake at Aquatica that they have made a breakthrough and will be offering their Canon 300D digital Rebel housing with TTL strobe control. Aquatica’s electrical engineers have “cracked the E-TTL code” for the Canon 300D and will install special circuitry between the camera’s hotshoe and the housing bulkhead that will enable the camera to communicate with underwater strobes for automatic, TTL strobe control.
One of Aquatica’s beta testers is trying out the 300D housing with TTL right now in Bonaire and should have a report in the coming weeks. We don’t know yet which strobes will be TTL compatible with the setup, but we hope to find out soon - so check back here for more information as it becomes available.
