Multiple routes to cut shutter lag

Question: I use a digital camera, which I generally like. But shutter lag irritates me. Is this something I just have to accept?

Answer: Shutter lag is the pause between the time the button is pushed and the picture is taken. It is a problem with point-and-shoot digital cameras. Digital SLRs have little shutter lag. More recent point-and- shoots are improving. Part of the problem is autofocus, especially in poor light. Using manual controls, if possible, will help. Also, when possible, press the shutter button halfway to compose the picture. When ready, finish pressing. And you may be able to speed things up by using sports mode. Finally, high- speed memory cards are helpful, if your camera can use them.
