A supply chain report suggests that the iPhone 16 Pro could use molded glass lenses to reduce camera bump thickness and weight while increasing magnification distance.
Molded lenses also provide greater magnification for their given size, so Apple could choose to keep the 28 mm and 120 mm focal lengths while using much thinner lenses. This would especially help with space saving on the smaller iPhone 16 Pro, which will already be overstuffed with the tetraprism crystal for the longer Telephoto lens.
Due to the complexity of developing molded lenses, manufacturers are already preparing for the iPhone 16 Pro lineup. Apple dominates supply chain orders, but other manufacturers may also attempt to implement molded lenses as part of a greater trend.
