But now the 16 Pro came out with very neat features ( action button, camera control button, 5x lenses, etc) and now I am looking at replacing my Canon DSLR with the iPhone 16 Pro for both 4K videos and photos.
Phone cameras have indeed gotten very good, but don’t expect it to look as good as what you were getting with the Canon. iPhones do a lot of heavy lifting in software, but they are still quite constrained by the hardware. Using an app like Halide helps.
