iPhone Duo zoom test: missing telephoto lens shows at 4x

Tom's Guide compared the iPhone Duo's zoom against the iPhone 18 Pro Max and Galaxy Z Fold 8. At 2x the difference is minimal, but from 4x the Duo trails both, and its zoom tops out at 10x versus 40x on the 18 Pro Max.

• At 2x the Duo's 'optical quality' shots are nearly indistinguishable from the 18 Pro Max
• From 4x the Duo trails both the 18 Pro Max and Z Fold 8 in sharpness and detail
• The Duo's zoom maxes out at 10x; the iPhone 18 Pro Max reaches 40x
• At 8x and 10x lettering in Duo shots blurs and merges together
