Tyler Stalman Field Review Finding

At f/1.4 with a 24mm equivalent lens at 1.5m, subject separation is extreme with dramatic background blur and high light gathering.

"The mechanical aperture on iPhone 18 Pro eliminates the fake lidar boundary errors on hair and glasses, delivering authentic optical falloff." — Tyler Stalman
