I have messed something up probably.  I am new at all this.  I love to take photos of coastal birds and I used to be able to put my camera on auto and CH and when I kept my finger depressed on the shooting button it would take multiple images.  I can't seem to get it to do that any more and when I press the button there is a lag time for just taking one image...help.  I do not know manual settings yet, but I used to do real well in auto.  Thanks.
