I try it on my K-r. K-r is able to set shutter speed highter than 1/180.
However, it works find when I use TAV mode in K-5.
Is any one has the same problem?
I think my K5+58AF-2 do HSS in Tv mode, I will check this later today to make sure...

YES!! Major overexpose problems. I always use fixed flash exposure compensation -1EV both buildin and external flash. Mostly this do correct the problem especially with buildin flash exposures are ok when putting also exposure compensation -0.3 or -0.7 Ev. But with 58AF exposures can not be trusted in PTTL at all cos it can suddenly overexposure many EV...sometimes I even need to use -5Ev without any reason. And also if I did take pic with -0.7 Ev exposure compensation and i did check histogram and changed exposure compensation to -0.3 cos little too dark then pic can be burnout totally. So its always needed to check every pic and adjust correction and hope for the best. Sometimes putting 58AF power off and on again helps also...sometimes not...
I think K5 have something to correct with its flash programming...and why flash exposure compensation range is limited to -+2Ev...and why not have manual flash power output for buildin flash.
One new thing that really is irritating with using flash also is when use wireless flash mode (in program mode M and then pttl flash) then SR is off...why why why pentax u do this to me...looks like it is needed to buy lens with OS anyway...this makes me wonder why i use pentax and not Nikon
