#Pentax #K01 #Firmware update solves #Sigma #Ring-flash issue

As reported in March (sorry - just German) the collaboration between Pentax K01 and Sigma Ring-flash EM-140DG did not work - the flash fired always full power and didn't care about the TTL-settings. This fault is gone after the latest update to Firmware 1.04 that was released last week by Pentax.
