Most compact digital cameras have very short shutter lag when shooting under normal conditions. The problem is that they all take longer when shooting indoors, under low-light conditions because they are searching for focus. DSLR's focus very quickly indoors, but they are quite expensive, but compact cameras vary. I have 2 compact Canons which focus quickly indoors, and I've read that Sony and Casio also are quick focusing cameras indoors. However, Nikon's compact cameras seem to have focusing problems in low light.
I want to get a digital camera that can take shots of my two children (2yrs and 3yrs,9mths). My two kids move like lightning so I need something that can keep up. It also has to be less than $300.00.
