that is a 'sensitivity' race, actually... Shutter speed, ISO, and Aperture in photography are related in much the same way as Voltage, Current, and Resistance. To change any of those three (in your case shutter speed) you have to compensate in one or both of the others. Lens aperture is limited mainly by form-factor (can't have a large aperture in a tiny zoom lens) and is therefore rather constant across Point-and-Shoot cameras. but Sensitivity can be improved by having higher-quality sensors and supporting circuitry. My first P&S camera had a maximum ISO of 400 and was very noisy at that level. my first DSLR did 1600 (4x as sensitive) and the current bleeding edge is 128000 (8x more sensitive again). Even in inexpensive point and shoot maximum ISO seems to be around 1600 (or more).

  He mentioned "blur" specifically which is a function of shutter speed, not shutter lag, the latter being the time between the press of the butten and the photo being taken. This too has improved over the years. The largest source of lag is the time needed to focus. Most, if not all cameras will focus with a half-press of the shutter release and will take the photo when you press down fully. This helps in some, but not all cases.

    I had both problems--blur, and a noticeable lag between pressing the button and taking the picture. As a layman, I am confused on the focus issue. Can't it just keep the image it is showing me on the display at the second I press the shutter? Doesn't it keep things in focus continually? When I went to buy a new camera, I couldn't find a single inexpensive digital camera that advertised itself as solving these problems. While I certainly don't even know enough to know what I'm looking for, it seems like a marketing lapse that no inexpensive cameras sell on speed as a feature.

      I would imagine that the currently displayed image is rather lax in focus, and that you can't get a great focus unless you can sweep over a range, too far to too short.
