Back to the problem - any progress?

I'm stumped.

I've read somewhere that there was some problem with flash exposure with K5. Do you have any other Pentax DSLR body to try the Metz 54MZ-4i with?

Stabbing in the dark here.. From the manual for the adapter..

Due to system-related reasons, the secondary
reflector of the 54 MZ... must not be activated in
the flash mode P-TTL

Yes? No?

I tested my PENTAX K-x with my Metz 54MZ-4i. It worked just fine.

Last week I visited PENTAX Services Center in Japan, and I have done some testing.
I tested my K-5 with PENTAX AF540FGZ in the Services Center, and it worked OK.
I also tested K-5 in the Services Center with my Metz 54MZ-4i in P-TTL mode. All the pictures I took were over exposure which was the same result of using my K-5.
After that, I tested K-r in the Services center with my Metz 54MZ-4i in P-TTL mode. It worked just fine.

I asked Metz Support whether or not they have tested 54MZ-4i with K-5 firmware version 1.02.
They said that they had confirmed the results of 54MZ-4i and PENTAX AF540FGZ with K-5 were identical. They have tested the K-5 firmware 1.01 and 1.02.

It seems that my 54MZ-4i is working OK except K-5. Also my K-5 is working OK with PENTAX AF540FGZ. It means that both my 54MZ-4i and my K-5 are working correctly.
So I have no idea what is wrong with 54MZ-4i and K-5 combination.

I always tested with deactivating the secondary reflector.

It was worth asking even if for elimination purposes.
