hey guys, i've been using my k100d for about two weeks and it's a great camera. But, i haven't been noticing if the k100d's most advanced feature is working or not; the SR system. Today i spent an hour testing it, (maybe i will post test shots later for you to see). After all, i'm really starting to doubt whether it is even there! haha. how do i know if it is working? how much shake does it reduce? any advice on how i should go about testing it? I will post test shots from any advice.
