I just got my very own K-5 yesterday, and was able to double-check a suspicion I had. My Metz 48 AF-1 is having issues with both of the K-5's that I was able to get my hands on. The flash is not operating in P-TTL mode when mounted on my K-5. Normally, when the flash is set to TTL, the LCD display should shift from TTL to P-TTL once I half-press the shutter to meter. However, on the K-5, the flash sticks to TTL. What's odd is that the flash does seem to be communicating with the camera, as the flash's head is changing as I adjust the zoom on the lens. But without the full P-TTL, my flash will overexpose when on the hotshoe.
Wireless P-TTL does work though.
Can any other 48 AF-1 owners confirm the lack of the "P" when in TTL mode?
Sounds like Metz and/or Pentax needs to update their firmware.
