200mm lens at 1/2 second exposure? Let's do the math and see what we were expecting of the SR......

1/200 (rule of thumb exposure)
1/100 (one stop)
1/50 (two stops)
1/25 (three stops)
1/15 (four stops)
1/8 (five stops)
1/4 (six stops)
1/2) (SEVEN stops)

So the second shot was taken at a shutter speed seven stops below what it is recommended one shoot on a camera with no shake reduction, image stabilization, or tripod....and you say "nothing too slow".

You can expect a 2-3 stop advantage from SR, and can sometimes get 4 or a tad bit more.

Shake reduction was one of the reasons to select K10D. Harsh conditions when hiking or in mountains (like Simon said), freezing cold, no stable place to stand or to put a tripod (or monopod) etc.

I think the half second or more is too much for the system.

Maybe a little bit too fast in judgement

I know my K100D Super has shake reduction, but does it do anything at all??

i think it does jack all. i've pretty steady hands and my elbows are pressed right up against my body, even when i lean against a wall photos can still come out shaky

what the hell is the Shake Reduction function even doing? is my camera broken or something?

heres a few samples, the first taken in indoors low light at 50mm, and second outdoor nighttime at 200mm. maybe .5s shutter time nothing too long

how much does the Shake Reduction actually reduce camera shake?

i'm getting a tripod soon, but when going on a trip you just can't bring a tripod along

Well, as quoted by other, since your first picture is taken @139mm (equivalent 24x36) you could expect being able to go down from the 1/125s to 1/15s (around 3 stops) with SR. Your chosen speed of 1/8s is one stop under that and is at the very limit of the SR specs, hence the slight blur.

The second one is a good one: with a 65mm lens, you should be able to go from 1/60s to 1/8s or so but 1.5s is almost 4 stops below.... a tripod is your best friend here

SR really works wonders, here's a shot from the galery I took last saturday using the DA 12-24 @1/4s and it is tack sharp but I don't expect getting away with sub 1 second shots, even with a wide angle.
