Here's something to try, and it's how I got used to my Pentax when I first got it (hadn't shot with a SLR in 20 years before that).
If your camera is on Program Automatic, look and see what the readout is showing for shutter speed, then go to Shutter Priority (manual selected shutter speed) and try a close shutter speed that's a little slower or faster, depending on the effect you want. Faster to stop the blades, slower to give more blur.
Watching what the camera does while in automatic mode can give you an idea of what you might like to try in manual mode for shutter speed or aperature.
