K-30 and Sigma DG ST 610


I purchased a DG ST 610 for both myself and my partner and we are both getting weird and unpredictable results in P-TTL. Does this flash not work in p-ttl on the K-30 ? It's very frustrating ! If it doesn't work I will return them to Adorama and get something that does...I'm no strobe master but I've never had these issues not even with my yn-565ex on my just works reliably so I'm starting to suspect something is really wrong.
Thank you in advance.

Sigma doesn't list any flash support for the newer Penax cameras (k5II,30,50,500,or K3).

I use Metz AF48-1 with my K30 and have no problems with it. I did have to update the firmware though. Sigma doesn't allow user firmware updates IMO that's a major disadvantage to the Metz flash system.

Thank you both very much! I suspected that was the problem as I noticed when I was about 6 - 8 feet from the subject would get what I expected when I noticed the strange behavior and started using the FEC because it was really in manual mode ,and not sending ttl just full power . I have flashes with more control in manual than this one and I wanted a p-ttl flash so back it goes, hopefully there will be something I can get on a Black Friday special with p-ttl.
