I wish I had 4 grand to spend on a NICE digi, but I am stuck with my cameras for now. One thing that helps is to use manual settings as much as possible. Especially the focus, shutter speed (or set on sports), then as said above push halfway down on the shutter until the optimal picture time.
Or do like me and shoot 28 pictures in a couple of seconds
My camera may be old school but it is still the fastest digi on the market.
