Hi, I ordered one of these small TTL flashes for my K-1 as a replacement for the lack of built in flash. The item received was labeled MK 320-P but the box and instructions were for Panasonic/Olympus cameras and would only work on manual on my K-1 and K-3. No TTL and there was obviously no communication between camera and flash. emailed seller via ebay and there response was that my flash is the correct one for Pentax..
Looking at the Meiki flash contacts compared to my 360FGZ there is an obvious mismatch which would explain the no TTL result, see photo.

Has anyone else had a similar experience with this flash?
