I learned that earlier thanks to another poster advising me. The photo were taken in 1X. I then cropped the photo manually on each.
You may have had 1x selected in the camera app, but the
metadata of your photo is showing it used the 0.5x ultra wide lens (because of the f/1.8 aperture). Since it was low light, the camera app likely chose to use the 0.5x ultra wide lens and digitally zoomed in 2x for the 1x shot.
If you have 1x selected in the stock camera app, it does not guarantee you'll be using the 1x wide lens. It will decide whether to use the 1x wide lens, or the 0.5x ultra wide lens zoomed in 2x based on lighting conditions and what it thinks will take the better picture.
The same goes for 3x. If you have 3x selected in the stock camera app, it will decide whether to use 3x telephoto lens, the 1x wide lens zoomed in 3x, or the 0.5x ultra wide lens zoomed in 6x.
The stock camera app does not give you control over what lens to use, whereas 3rd party camera apps like Halide do.
