    Anyone here owns this flash and had it upgraded or "rechipped" as we read from other forum?? it seem like this flash does overexpose most of the time, and i had tough time controlling it.. its unlike when I was using the Ds....

    Not a Pentax user but I have a Canon mount one. Mine has very inconsistent power output as well. Worse of all, after only slightly more than year the thing died on me and cost $80 to repair. Do yourself a favour and get another flash as suggested by sbc.
