Shake Reduction

Hey all, new Pentax user, new DSLR owner... (k10d)

I was persuaded to by Pentax becuase of the shake reduction (I wanted to take pics of my various friends in bands with stage lighting).

My question: How do I know this is actually working? It almost seems so subtle that I can't really tell at all. Or maybe it isn't working... I read through a number of posts and it seems that some say that theirs was non-functioning. I bought this used from ebay, but it was hardly used at all.

Anyway... is there a sure fire test? Magic Lantern offered no insight..

Thanks all!

Just so you know SR will not prevent motion blur caused by your subject moving. It will buy you a couple more stops of performance in lower light and compensate for camera shake. On my K100D when I am about to take a picture and SR engages I see in the viewfinder an icon that matches the SR switch icon in the lower right hand corner. That tells me SR has engaged.

1) Take the lens off and shoot a picture at a 1 second exposure while looking into the camera. You can see the sensor moving around.
2) Take a picture at 1/8 second or so (presuming a normal focal length lens) with shake reduction turned off, and then take the same picture again with the shake reduction turned on. Compare the results.
This is also a good way of seeing what the limits are for shake reduction for you, as this is rather variable.

Don't forget to wait for the SR icon to light up in the viewfinder before pressing the shutter release all the way. It doesn't fire up instantly.
