Thanks boriscleto, I did catch that.
But there is no reason to be worried about P-TTL if you will use the flash only with a P-30T. If one would like to save money then an inexpensive 5$ Ebay Vivitar flash will work just fine, maybe even better, on the P-30T.
I felt, and perhaps should not have, that it would be useful to know how to ensure the flash can be used between both digital and film cameras.
However, feel free to ignore the information if it is not needed.
