As described in The NY Times, getting an accurate description of a cameras shutter lag (the time between pressing the button to when the image is actually saved) is nearly impossible. Since there is no standardized measure of shutter lag, comparing one manufacturer to the next can not really be done. So is there an easy way to minimize shutter lag?
