Iphone 15 pro Zooms In On leveling

I just got an iPhone 15 pro and when I have it on the tripod and try to level it a little it zooms in automatically. Don't have the problem in my truck on a different computer. Does anyone have this problem?

How else would you rotate a rectangle, and still keep it inside its original footprint, which in this case is the camera sensor? If you're already zoomed in digitally (which is actually cropped), then it's possible to rotate it without zooming any more. But if you're all the way out, then it has to.

I am in a studio, and I have a leveling adjustment on my tripod head, when I move to adjust the level of the output, it zooms in. like I'm zooming in by turning the adjustment. If I disconnect the phone and am shooting video on the phone it doesn't zoom in when I level by hand. See the video attached Look at the top of the screen and it zooms in, with no leveling adjusted.

Yep! That's exactly as I would expect. If you exactly fill the sensor, and then rotate the image, then the corners would not have physical pixels anymore to record them. So to avoid having black corners where there's literally no data, it zooms in just enough to put the physical edge of the sensor on the edge of the screen again.

If you start with it already zoomed-in, then I would bet it doesn't do that, until you rotate enough that it has to. Or, the software could be made simpler by always adding that amount of zoom regardless.

I don't know which way Apple went with *that* choice, but that's what it's doing. It's fitting a rotated rectangle entirely inside the original one, which requires it to be smaller. Then that smaller rectangle is expanded back to fill the screen, which results in a zoom-in.

Re-reading the question, what are you actually asking?

My first take on it, and what I answered, is, "How to keep the full-frame as it rotates?", which is impossible without a circular sensor, which I'm pretty sure you don't have.

Are you actually asking, "How to not rotate the image as the camera tilts?" That's probably a question for Apple, because it's happening in the phone.
