The camera system inside the Galaxy Z Fold 4 features a 50MP main sensor with 23 percent brighter pixels (than the Galaxy Z Fold 3) and a 10MP telephoto unit with a longer 3x zoom range and 30x Space Zoom, up from 10x digital zoom on the current telephoto module. The 12MP ultra-wide camera is the same as the one used throughout the S22 family, and on the previous version of the foldable as well.
When it comes to the Galaxy S22 Ultra, we all know how powerful that camera system really is - from the main module with 108MP sensor to the insane Space Zoom. In the table below you can take a quick glance at the camera systems in both models.
