    That's it. I want focus trapping badly. Just wanted to get that off my chest.

    I want it now!

    That would be an awesome 4.0 firmware.

    I would think it would be easy for Olympus to accomplish, all they do is to set the Release Priority so that the shutter will not fire if the lens is not in focus. Which is what the intent of Release Priority was supposed to provide us the option of!

    What is focus trapping?

    The camera takes a picture only when what's in the focusing box is in focus (without shifting the lens elements and refocusing).

    Thanks. I thought that was the same as release priority.

    Roughly the same, the only real difference is the camera won't try to refocus and rather waits for the subject to move.

    I see. So the lens is pre focussed, or manual focussed on a specific point. And when the subject passes that point the focus trap just triggers the shutter.
    Thanks.
    Is this for wildlife? Or sport? Or kids wild parties?

    It can be used for wildlife (stationary ambush camera) however one of the main uses I've seen is adapted manual focus lenses, you hold the shutter down and twirl the focus ring - As soon as it kicks into focus it takes a picture.

    My intent would be wildlife and sports...to setup the camera on tripos, focused on the point of interest, like just off of a perch, waiting for the bird to fly though. In the backyard, snapping the small, darting birds in flight is very challenging. But I know,where the feeders and afforded perches are, so it seems a strategically selected focus point would be a great way to put a camera n a tripod, go get my coffee and check back in a few.

    For sports, less interesting, but I could also see that perfect spot to,grab that "shot at the net" and wait for it. More interested for wildlife though.

    That is NOT the sort of automation I am interested in!

    The camera will automatically take a picture when an object appears in the focus point and depth. Imagine the scenario where you setup a hummingbird feeder and set the focus point a foot away, at the same depth. The camera will wait until an object flies into the specific area, focus and take the picture. No feeder in view, nice BIF shot.

    One way to get pictures that take a lot of time and good fortune to get typically. I've been trying to get a hummingbird in flight all season. They come and go so fast!
