You're missing a key part of the name. Are you asking about the Sigma EF-500 DG ST, or Sigma EF-500 DG Super? These are two different models, with significantly different performance capabilities.

Sorry Dan...I know there are two types...did not realize I had left the Super out (makes a big difference). It is the super version. Thanks for pointing out my mistake. Alexander

I have owned an EF-530 Super for the past five years. IME, it is a capable and reliable flash. I don't think there's much of a difference in the two, just a slight difference in power (guide number 50 vs. 53). The only caveat I would mention about the older EF-500 is that it may need a firmware update to work on a current Pentax body. Sigma provides the updates for free.
