I have a Nikon DSLR that I use when I need a fast shutter and an older Canon Powershot for taking pictures of things that don't move very fast. There are two aspects to shutter speed, how short the exposure is and how quickly the shutter snaps after you push the button. That last one is what usually gets you on a compact camera. You push the button, the camera clicks and whirrs a couple of times setting exposure, focus, etc., and then the shutter trips just in time to get a great picture of smoke on the pad. The DSLR takes the picture when you press the button. Now if only I could tune up my reflexes.
