Only HSS works!

I use Pentax and Pentax Flashes. Today I discovered that I dont get enough light when fireing at spedds below HSS, that is for example 1/160 s. Then the images are very dark, even though the flash fires! Why?

Regards Jens


  • Have you turned on the HSS feature on the flash. It's HS on the Pentax flash.
