SUMMARY
A review of the iPhone 18 Pro's new variable aperture lens found that its widest setting (f/1.48) performed better than anticipated, with no visible diffraction at f/4. Despite predictions, the ultra-wide, telephoto, and front cameras appear unchanged from the previous model, and the main camera may also use the same sensor. While the aperture range offers depth of field control, especially at minimum focusing distance, outdoor shots in ordinary light show minimal difference compared to the iPhone 17 Pro. For videography, the aperture can help achieve natural motion blur but may still require neutral density filters in bright daylight.
