My camera’s 20x optical zoom is invaluable for revealing the appearance of a given subject. It works best if I am 90 cm or a metre away. But, some subjects, like the small and tiny moths I filmed on the garage today, can benefit from bringing the camera as close as possible to them. One of its features is the button which allows a zoom at a pre-set slow or fast speed, but which can also be pressed to give very gradual increments of proximity. I was able to get much better close ups of the moths this way than by being on full zoom.
