Originally posted by Delahaye303 brilliant, shutter speed was the culprit. I was shooting on 200, which didn't seem excessive to me. Dropped down to 125 and they're now working. I've ordered a sync cable, do you think that will allow me to shoot at faster shutter speeds?
Yeah,sadly Pentax cripples their cameras by shutting off the flash completely if you exceed the sync-speed (1/180s) and you cannot fire any flash unless it is a PTTL-HighSpeedSync (HSS) compatible flash.
Most brands allow the photographer to use flash above the sync speed -- and it has its uses.
But Pentax thinks you'll just poke your eye out with that, kid.
