Yes, Pentax crippled the hot shoe or restricted the same, in example to 1/180s speed on K-3 or K-5II only, where other manufacturers goes higher and also the firing signal for the hot shoe central pin is disabled as long as you pass max speed of 1/180s. Even Olympus PL-1 allows you to goes higher than this, and with flash on the 1/1 power which extends the duration of the flash pulse, speak faster available time leads you to faster sync speeds.
