Shake Reduction Problem

Hi all,

So I recently got my Pentax K-5 and love pretty much everything about it. However, what I do not love is what seems to be persistent inconsistency with my SR. I have a Sigma 17-70mm f/2.8-4, and while I frequently get some very sharp shots with relatively slow shutter speeds (though anything slower than the 1/focal length rule is almost never acceptable), oftentimes, with the Sigma's OS turned OFF, of course, I will find even at 17mm and 1/50sec the image will come out blurry! Is it possible that something in the lens is screwy, as in the elements are moving about even with the OS turned off, that my hands are unbelievably shaky (and I'm 19y.o., while my hands are not the steadiest I don't see how I could be unaware of them being quite that shaky), or (dare I say it) that my k-5's SR is just plain faulty due to some sort of calibration error? Has anyone else experienced a problem like this?

Thanks in advance.

If you shoot before the hand icon appears in the VF, you risk getting blurry shots. Do you think that was the case?

I sometime wish if there was a setting which forces one to wait till SR is stabilized (much like AF)

The SR confirmation icon (hand icon) takes about 1-2 s to come on once you half-press the shutter button. Usually I found myslef waitng first for the AF focus confirmation icon ,(green hexagon) and then I check that the SR confirmation is on.

I suggest that you try again and pay attention to the SR confirmation icon.

Hope that the comment may help.

The slowness of the SR working has caused me a few blurry shots in the past when I've been out shooting impulse peopel shots. the mechanism isn't quick enough to keep up. Best to leave it switched off unless light is low.
