Speedlite flashes for Pentax cameras
A speedlite flash for your Pentax camera must be compatible with Pentax P-TTL metering for automatic exposure control. To get this you don’t have to buy a speedlite from Pentax. Alternatives include flashes from Yongnuo, Godox, Pixel, Shanny or Meike etc. Apart from the TTL enabled speedlite flashes there are also manual flashes (without TTL metering) which are less expensive but lack some features.
