I do all sorts of photography, but lately I've been shooting sports events, specifically soccer. For some reason, the last two weeks (two weekend tournaments) my D300 has been having some shutter lag/delay when I hold down my shutter button in high speed shooting. I've actually missed a few shots. What is weird about it, is that this is new. I've had my camera for about a year now and never had this problem. I thought maybe the battery was low so I charged it full and the same problem occurred. Hmmm???
