Thanks, I did not know about the possible high voltages and wondered about the synchronisation as digital cameras use a preflash to set the exposure. I see there is an external flash socket on the E20p but I have never tried it out. I suppose you set the film speed to 100 iso and then use a flashmeter to calculate the exposure. I suppose you keep the pop-up camera flash popped down. Since I've not used digital flash yet with this camera, I will try it out before the job on Tuesday. MUST THINK CLEARLY.
