iPhone 15 Pro Max’s Tetraprism Camera

The tetraprism camera on the iPhone 15 Pro Max packs a large lens into a compact phone.

The tetraprism is similar to a periscope lens, however it is formed by folding a prism into waves rather than spinning a long tube of lenses.

For years, periscope lens rumors have swirled about the iPhone, but now that it's arrived, it's even more intriguing than expected.

Apple is employing the periscope concept, but without the 90-degree twist. Instead, four links have been inserted into an internal prism.

For many people, especially those who shoot a lot of pictures, this single-camera boost may be enough to justify purchasing a new phone.
