I've got a pentax af220T flash, and set on camera to try to using it.

And it works! But I am afraid if it will harm for my rd1.

Any ideas guys?

Cheers

Kris
 
It's only the trigger voltage thats an issue. Some early flash guns have trigger voltages over 600 volts. Most modern digtal cameras will only cope with about 25 volts (some 250). Any more will 'fry' the the camera circuits :bang:, but the flash gun should be OK :D

This flash use 4 AA batteries, it might be fine. Thanks man.
 
Don't make the assumption that a flash powered by small AA batteries are not capable of high trigger voltages.

You can measure the trigger-voltage yourself between the big contact in the middle and the (or one of the) outer contacts that connect to the case of the hotshoe.
A simple multimeter in AC-mode works for this. Remember that the flash has to be "on" and fully loaded.
