Yep. I would say try it for your self. I have read that the shake reduction is worth 1 to 2 stops...What does this mean exactly...On my fast lenses it is faster with the shake reduction off. No doubt about it. Shake reduction in low light, really slows up the auto focus. I have also heard this to be true of image stabilized lenses for both canon and nikon so It is not a pentax problem..I think it is simple physics..Before it fires it must stabilize.
I also read that when using flash, to turn of the shake reduction...I have down this and the camera responds very quickly and the pics are sharp.
These 4 shots were taken at the zoo last week with no shake reduction. My little K100D super was kicking but. No way would I have got this sequence with shake reduction on. I may have gotten three pics, but not four...These were also shot at ISO 800
