How can I use the PowerShot Pro70 with studio lights?
We have discovered that if you put a standard hotshoe to PC adapter on the Pro70, AND select an aperture from the menu, the shutter speed of 1/90 is automatically chosen. We have also had some users who have even had success with their existing infra-red flash triggers on the Pro70! Please note that even with the Speedlite 380EX and 220EX units, in aperture mode the camera does not control the flash output, you only get full flash output.
