I use it in some wildlife situations.

There are eagles where I live. They eat the dead salmon in the rivers. I scope out a popular dead fish that is getting some attention. Then I set up my camera on a tripod. I set the focus to that an area of about 3 feel is in good focus. Then I turn it to manual focus. That way it does not change. Then I step back and use the remote anytime there is action I like in that 3 foot area.

I do a similar thing with flowers visited by hummingbirds. An area of about a foot is in focus. Step back and use the remote to clid when a bird is at the right angle inside that little area.

I am not using the rings on the lens to focus. I am just setting it to manual so it does not change.

Or, if I am taking a photo of a stationary thing, I will use manual to get the focal point on my subject. When the subject is moving, I need the above method.
