Test shows how much the iPhone 18 Pro's wider f/1.48 aperture changes bokeh

9to5Mac compared photos from the iPhone 18 Pro's main camera at f/1.48 and f/1.8 to gauge the difference in optical background blur. The effect is visible on nearby subjects but nearly imperceptible on distant ones.

• iPhone 18 Pro shoots at a maximum aperture of f/1.48 versus f/1.78 on the iPhone 17 Pro
• The gap between f/1.48 and f/1.8 is under one stop and shows mainly on close backgrounds
• All test shots were taken at the same distance and focal length for a fair comparison
• The blur in the test is optical, without Portrait mode or LiDAR processing
