Focus Trap as a Camera Feature

A relatively unknown but very interesting feature
I came across something interesting yesterday. Some cameras have a feature called a trap—the focus trap.
I had never heard of it before. It’s probably not for everyone, but definitely useful if you want to capture wildlife.
I found it fascinating.
Here’s the article: FOCUS TRAP

It's really a great setup. You focus the camera, go grab a coffee, and when the bird shows up, the camera takes the shot. The big advantage is that the bird isn’t distracted by us, and the focus trap is definitely faster than a person.
But I’ve never tried it before. I’m going to dig out an old camera now and give it a shot.

@Andreas Palmen Then the coffee should be enjoyed nearby. Otherwise, you'll come back to find the trap triggered but the camera gone... 😜

I've tried this a few times but eventually gave up. The camera does trigger as described when the object is within the focus area, but depending on the object's speed and the camera's shutter delay, the object can already be out of focus by the time the sensor actually captures the image. This method only works with subjects that are suitable for it—and there are fewer of those than you might think. It's better to switch to manual focus, set the focus precisely where you expect the object to be, and then, when the object arrives, switch to continuous shooting and trigger the shutter manually. This way, your chances of getting a good shot are much higher.
