Just tried Metz 44 AF-1 on K-1 and could only use M mode, the flash would not fire in TTL mode. Works fine on K-5.
I've fired a report to Metz and will add any response I get from them here.
Originally posted by pid I think it has to do with the fact that the new flash sync time is 1/200s and not anymore 1/180s
I've tried setting sync speed to 180 in the config ('C' Page 1, '7 Flash sync speed', option 2), but still no go for pTTL.
Response from Metz:
Thank you very much for your e-mail enquiry of 30 April 2016.
We regret the trouble that you have with your flash unit 44 AF-1 respectively with your new digital camera Pentax K-1.
Unfortunately, this new digital camera Pentax K-1 is not yet available for us for testing purposes. For that reason this type of camera is also not yet mentioned on our homepage.
Since last Friday we heard also from a few other customers that there are problems with the new Pentax K-1 in P-TTL flash control mode.
So we guess that this type of camera works different to the former Pentax digital cameras (K-5, K-5 II, K-3, K-3 II, K-30, K-50 and so on) and this will lead to some trouble.
Our development department will try to get a new Pentax K-1 in order to fix the problems as soon as possible. However, we fear this will take some time.
Regrettably, at the moment we can’t supply you a fast solution for that problem.
However, we will inform you immediately by e-mail when there will be any news concerning this problem.
We regret to have no other information for you at the moment and remain
With kind regards
Wolfgang Becker

I can confirm the problem does not exist in crop mode. Information passed on to Metz. Thanks Tjompen1968!
