Technique is a factor as well. Hold your arms against your body and hold very still when you push the button, and then if possible also brace yourself against something solid, or better yet, brace the camera against something solid. In other words, keep the camera as still as possible when taking a picture, especially in low-light situations and/or use the flash. (In automatic mode) the cameras adjust their exposure times according to the amount of light.
