K-r has lots of problems in its automatics. Is this again one issue?
Do I really have to use Tv mode or fully manual mode to get reasonable shutter speeds?
It is not the K-r (neither the model nor your specific camera). I also have the Metz 44 AF-1 but "only" the K200D and it behaves the same way in P and Av mode as you describe (that is, with modern autofocus lenses - I'll come back to that).
But, there is nothing "wrong" in this as far as I am concerned. Both our cameras allow for "Trailing curtain sync" and "slow-speed sync" which is a desirable feature (see your manual on the use of exsternal flashes and the Metz manual on these features) and so does the Metz 44 AF-1. So yes, if you are shooting moving objects you should use Tv and set the standard syncronization speed (1/180 s on the K200D) for "normal" flash photography and lower for the TC-sync and S-s sync).
For me (who learned to photograph in 1960) there is nothing unusual in having to set the sync. speed manually. In these days we had the fantastic sync speeds of 1/30 s for bulbs and 1/60 s for electronic flashes !!! And, of course, we had to set these speeds manually.
But now comes the curious part: If I use one of my old 1980'ies Tamron Adaptall KA-lenses rather than a modern autofucus lens
THEN the camera automatically chooses 1/180 s as sync speed in P and Av mode. And no matter what aperure I set in Av, the camera chooses the same speed and regulates the power accordingly. (We are talking TTL-operation of the flash, obviously). Don't ask me why and how this difference comes about. It just does.........
