I believe this problem began before the 14.5 betas. I’m using iOS 14.4.2 on my iPhone 12 Pro Max. I selected 2.5x lens with either stock Camera app or ProCam 8 and took photos of the same object indoors with incandescent lighting. ProCam used f/2.2 lens but Camera used f/1.6 lens.
Lens selection - yes. however it was for low light situations (using f1.6 zoom instead of f2.2). What has been happening is the lens selection is now going for the f1.6 zoom in moderate light instead of f2.2 also. On top of that many of us are seeing less fine detail than we used to in previous builds. A softening of the picture.
Yep - ProCam, ProCamera, and Halide all have no issue with selecting the correct lens for 2.5x. 👍
