As you know, Pentax flashes are rare and expensive. I have a Yongnuo flash for my Nikon DSLR and it's great and reasonably priced. I bought this for my Pentax K5 and I am very satisfied. TTL is very accurate and has many manual power settings. Very high-quality workmanship, without cheap materials, non-slip. Worth a try.
