Thanks for the confirmation. I starting this thread because I had a bit of a panic when I first started using the flash that perhaps I had damaged the K-5 contacts when using an old Minolta flash with the camera. I found the Minolta flash unreliable until I insulated two of the pins from making contact in the hot shoe.
Just to add more data, what version of firmware do you have in the camera and flash. I'm running either 1.12 or 1.13 on the K-5, and V2 for the flash. Both have scope for updating, although I'm not expecting any fixes.
