Originally posted by GerryL The Tumax made flashes by the way kinda lose their P-TTL when bounced (when flash head is angled, automatic flash setting place it on "manual") since the flash goes to full manual power (compensating for the bounce).
But...that kinda blows the whole purpose of having a P-TTL auto-exposure flash, so then you may as well set it manually by the guide number, if you have to get the right exposure by trial and error with EV compensation ! Also makes "candid" shots a lost cause.
I have a couple of old auto flashes (Pentax AF200T and AF330FTZ, and Vivitar auto thyristor 3700) that I could try out, but am a bit leery of the trigger voltage issues... I don't want to fry my K10D ! So, has anyone tried any of those flashes, either in auto or manual mode, and are they safe ?
Thanks to all responders !
