Just as a reply; I don't want to hijack the thread.

It's not because I prefer Metz (but my first flash was a 45CT1 loooooong ago). I do think that they, in general, offer better value for money.
What I'm saying is that there are issues with the K5 and pTTL; you can search the web. So don't blame the Metz straight away
I experience inconsistent exposure with the combination of K5 and AF540 when bouncing in pTTL. I'm now starting to switch to A-mode but unfortunately loose the AF assist of the flash in that case. Usually not an issue as the K5 has its own one, but the one of the AF540 is more powerful which is sometimes necessary.
I haven't used the AF540 for a while on the K10D and K100D, but seem to remember that I did not have the issues; but I also did not use flash as much.

There was no pTTL in the film era; there was TTL
