So, it is still an ISO 10330 complaince, for the *voltage* part. However, the maximum toleratable discharge current is still unknown!
ISO 10330:
Photography - Synchronizers, ignition circuits and connectors for cameras and photoflash units - Electrical characteristics and test methods - ISO 10330:2002 Originally posted by roscot ... K10D and K100D/110D. There has been a few threads here and on other forums lately concerning safe trigger voltages for the K10D and the K100/110D. People have been guessing, but there have been no hard facts.
So, today I called Pentax Imaging USA, to find an answer.
Thanks to Tim at Pentax, the answer is 25volts. That's 5 less than the ist *Dx series cameras. Any flash with a trigger voltage of less than 25 volts should be safe to use.
I hope this information proves useful.
