The shots I need to get require me to zoom in a lot on my BMPCC while using a stabilizer. Most of them are tracking shots. Im finding it hard to keep it smooth and precise. One shot has me tracking a guy walking, and then he stumbles upon an object which comes up in the foreground, but the foreground object usually comes in so suddenly that it's hard for me to get a nice clean shot. How do you get nice long lens shots while tracking?
