Great overview, thanks!
Originally posted by beholder3 The list focusses on Pentax dedicated flash equipment obviously.
I don't see how it does as you include a lot of flash equipment that is not Pentax-dedicated (e.g., from Yongnuo and Godox).
I encourage you to include the
Cactus RF60 in your list. It works with Pentax cameras just as well as Yongnuo or Godox equipment but has the unique advantage of supporting manual HSS.
Through a couple of optical triggering techniques (requiring one HSS-capable flash) or with a
workaround (not requiring any P-TTL equipment at all), it is thus possible to do off-camera HSS photography with a Pentax without breaking the bank.
BTW, the Cactus V6 supports "HSS" just as well as "SuperSync". Both are not supported as native P-TTL subfunctions but one can achieve the same effect (with some manual settings). In the same vein, the Cactus V6 also supports achieving the effect of second-curtain sync. Again, not as a native P-TTL subfunction, but through the option of using manual delay settings.
