I've tried my metz 52 af-1 with my pentax k-5 in wireless P-TTL using the camera flash in controller mode.
the results are ok with:
Pentax SMC-A 50 f 1.7
Tokina 80-400 f 4-5.6
got significative overexposure with Pentax SMC DA 18-135mm f/3.5-5.6 ED AL (IF) DC WR, worst with white surfaces, from 1 to 2 EV.
It seems that the problem is reduced setting the flash zoom manually to 105 mm.
I'll do more test and post the results. I still have to try with my sigma 50 f 2.8 macro.
