Originally posted by comprock Auto detection for Pentax Metz flashes probably doesn't work, but the profile for the Metz 52 AF-1 should be there and is set it manually.
I'm afraid while the Metz 52 AF-1 is supported for Canon/Nikon, there is no dedicated profile for the Pentax-dedicated version (yet?).
So it appears that if the model cooperates at all, it will have to do so with a generic "Pentax" profile.
Note that
another user currently has trouble with a Metz 52 AF-1 on a V6II and a K-1. You may want to observe how this case unfolds before you expect the Metz 52 AF-1 to fully work with the V6II. That user so far has only tried other Metz for Pentax profiles, so all could still be well and as a matter of fact should be according to the Cactus employee.
