I have the Sony DSC-S50 and it has 2 features which are nice for shots of moving planes. First, it has a fast focus mode and secondly, it has a freeze settings mode which is activated like many SLR's. Depressing the button half way freezes the focus and exposure. Then when you press that last little bit you have an instant photo. I would assume others must function along these lines?? The down side of the S50 is that is has no optical finder. One quickly learns to just sight over the top of the case; crude but it works. The next better model (S-70) has an optical finder.
