Reading between the camera lines, there is good news in that the telephoto lens is 48 megapixels, which means its 4x optical equivalent of about a 100mm lens is as good as the main camera. It's less than the 16 pro max, which has 5x, but at 12mp. But on the plus side, at the same megapixel resolution you can zoom the telephoto out to 8x 200mm and get the same resolution as the 16 pro max at 5x (using the middle 12 megapixels). But those pixels will be smaller. Overall, an improvement but not as massive as advertised imo.
The camera will still have 'jumpy' resolution. The main camera has 48 megapixels, but handles all zooming out to 4x. If you zoom out to 2x, you're using the middle 12mp and 'wasting' 12. Zoom out to 3x and you're using 5.3mp, and just before 4x you're only getting 3mp. Then at 4x it will jump back up to 48mp!
So if you want to zoom out to say 3.5x and you're going to want to use the image on a big screen, you're much better off to use 4x.
That said, I believe there's some 'clever' software miracles happening in there, where it can blend images from the various cameras to get better resolution in the central image.
