Whats the best technique for using the zoom lens?
If your lens can be manually zoomed, do so whenever possible. That saves time and battery power. Where possible, zoom between shots rather than during them, and try to edit zoom shots out of your final tape. When planning to zoom in on a subject, zoom in before you shoot, set and lock focus on that subject, then zoom out to the start position. This will ensure that the important subject is in focus throughout the shot.
