As far as I can see, there isn’t a definitive resource listing the current and past P-TTL flashguns that are fully or partially compatible with the K-1. I think such a list would be valuable for members and those externally seeking information on this topic.
According to the user’s manual, on page 111, the manual only mentions the Pentax AF series flashes as being compatible with the K-1. It would be great to have a list of third party flashguns with their functionality listed for people to discern which flashguns would be suitable on the K-1.
Please add your experience with the range of P-TTL flashes available, past and present, no matter the brand: Metz, Sigma and the like.
Here is the working list thus far:
1. Sigma EF-500 DG Super. Works without pre-flash, dialling Flash Exposure Compensation down to -2.0 EV.
2. Metz mecablitz with the latest firmware:
Metz 44 AF-1 / 48 AF-1 / 50 AF-1 / 52 AF-1 / 58 AF-1 / 58 AF-2 / 64 AF-1. All work without AF beam, HSS and master/controller in wireless flash features.
3.
Godox Mini Camera Flash TT350P
4. Yongnuo YN-585EX. Works without AF assist beam and HSS.
